What steel is the sharpest for knives? What steel makes knives sharpest ranked

Carbon tool steels and high-speed tool steels.

So, what kind of steel makes knives the sharpest? What are the features?

First, the grains of steel should be fine and dense. Because the grains are small and dense, it is possible to sharpen particularly thin blades.

Second, the hardness of the steel should be high. Because steel that is too soft is easy to curl, the formation of burrs greatly affects the sharpness. Like the commonly used razor blades, the cutting edge is generally coated with ultra-hard ceramic, and its sharpness is undoubtedly high.

Third, steel should have strong toughness. The high-toughness material is good for cushioning pressure, making the cutting edge less prone to curling, which can improve sharpness.

Fourth, the pattern. Several different steels are folded and forged to improve the fine density of the grains, as well as their hardness and toughness. What's more, the pattern is also formed.

The sharpest known in history is the Damascus knife, this Damascus steel.

It is folded and forged, which can easily cut paper and break hair in the air, which shows that the pattern also has a certain impact on sharpness.

The knife, one of the eighteen weapons, one of the nine short and nine long, and the first of the nine short (knife). The knife is a short weapon with a long blade on one side. At the same time, it generally refers to tools that can be used for cutting, cutting, cutting, chopping, and stabbing, and is also called a meal utensil together with a dagger.

In fact, the waterjet is a kind of machine that uses high-pressure water flow to cut, when the water pressure is increased to 100-600 megapascals, it can form a high-speed jet of 800 1000 meters per second, and the ultra-high energy contained in the jet can cut some soft materials.

Several types of steel are suitable for knives.

Carbon Tool Steel:

From T7 to T13, a A on the back indicates high quality. can be used to make knives, and the main materials for knives 70 years ago were these things. These things have relatively high requirements for the process, because they are brittle, poor hardenability, rusty, easy to anneal, and cannot be cut at high speed.

However, today's razors, files, clippers, scissors and other cheaper tools are still mostly made of these materials.

High-speed tool steel:

The common ones are W18GR4V, W9GR4V2, W6MO5GR4V2, W9MO3GR4V

These raw materials are heated to 1200 1275 in a salt bath furnace or chamber furnace and then oil-cooled, tempered at a temperature of 540 570, and the hardness HRC is not less than 63.

High-speed steel is widely used in the industrial field, and it is also the main material for people who do not have heat treatment capabilities. When I was younger, I used to sharpen my knives with millimeter-thick high-speed hacksaw blades, but now there are fewer millimeter-thick saw blades, and most of them are millimeter-thick. I can still see this saw blade sold at the thrift stall on Chaotiangong Street (10 yuan a piece), but you usually have to use a bit of brains to install the handle, I used to use epoxy resin, but now there is an electric spark to punch holes, which is easier.

This material has a carbon content of 1% or more, so the carbon content is not indicated in the first place. Several common domestic high-speed steel grades are as follows:

The hardness can be quenched to HRC=66, there are two domestic tool materials, W7Mo4Cr4V2Co5 and W2Mo9Cr4VCo8, which have good red hardness and no friction softening problem.

However, the domestic material with the best comprehensive performance of the tool is still 9CR18MOV (corresponding to 440B in the United States, SUS440B in Japan, X90GRMOV18 in Germany and France.

In fact, it is not bad to use 9cr18mo when you can't find 9cr18mov, the material corresponds to the Japanese SUS440C, the American 440C and S4404. The cheaper scalpel blade is made of 9Cr17 material, which is sharp and hard, but the corrosion resistance is not as good as the above material (the grain boundary rust problem of the material is not solved).

There are also commonly used common alloy steels such as 8mnsi that are more hardenable than ordinary carbon steels, and can be used to make woodworking chisels, saw blades, and blades.

CR06 is wear-resistant, has high hardness, but is not highly hardenable (usually supplied as a strip), brittle, and easy to break. It is used to make razors, sharp cutting knives for surgery, scrapers, gravers, files, etc.

Hello dear, glad to answer for you. Knives made of carbon steel are the sharpest. Carbon steel in terms of strength and hardness, is undoubtedly the king of the knife industry, with it made of knives, not only cutting performance, good impact resistance, but also tough and durable, easy to polish (sharp edges).

Knives made of folding and forging are the sharpest. The sharpest known in history is the Damascus knife, this Damascus steel is folded and forged into a loss, which can easily cut paper and break hair in the air, which can be seen that the pattern also has a certain impact on sharpness.

Summary. Hello, glad to answer for you. What steel makes knives sharpest ranked1. Tool steel.

Tool steel is one of the most widely used knife steels, and is welcomed by many tool manufacturers because of its advantages of affordable and balanced performance.

Tool steels retain high hardness and good red hardness at high temperatures, as well as have high wear resistance and proper toughness. It is mostly used to make cutting tools, measuring tools, molds and wear-resistant tools.

2. Stainless steel.

Stainless steel, as the name suggests, is the addition of chromium elements to the basic carbon steel base to make it corrosion-resistant, so that the knife finish is greatly improved, and it is difficult to rust if properly maintained.

But it is also because of this that the fatal disadvantage of stainless steel knives is caused: insufficient strength and toughness. It does not have excellent cutting performance in any effective hardness range, and is even brittle due to its lack of toughness, and it is difficult to sharpen.

Carbon steel is undoubtedly the king of the knife industry in terms of strength and hardness, and the knives made of it not only have good cutting performance and impact resistance, but also are tough and durable, and easy to polish (sharp edges). It is often used to make fighting knives, survival knives, household machetes, etc.

However, it is also because of the low chromium content in carbon steel, so it is very easy to rust.

Hello, I'm glad to answer for you, it will take some time to sort out the answers, please be patient.

Hello, glad to answer for you. What is the trap of Bi Gang making knives the sharpest ranking. 1. Tool steelTool steel is one of the most widely used tool steels, and has been welcomed by many tool manufacturers because of its advantages of affordable and balanced performance.

Tool steels retain high hardness and good red hardness at high temperatures, as well as have high wear resistance and proper toughness. It is mostly used to make cutting tools, measuring tools, molds and wear-resistant tools. 2. Stainless steel stainless steel, as the name suggests, is to add chromium elements to the basic carbon steel to make it corrosion-resistant, so that the finish of the knife is greatly improved, and it is difficult to rust if it is properly maintained.

But it is also because of this that the fatal disadvantage of stainless steel knives is caused: insufficient strength and toughness. It does not have excellent cutting performance in any effective hardness range, and even lacks toughness, is very brittle, and is difficult to sharpen.

Third, everyone must have heard such a sentence of carbon steel: carbon steel is king. Carbon steel is undoubtedly the king of the knife industry in terms of strength and hardness, and the knives made of it not only have good cutting performance and impact resistance, but also are tough and durable, and easy to polish (sharp edges).

It is often used to make fighting knives, survival knives, household machetes, etc. However, it is also because of the low chromium content in carbon steel, so it is very easy to rust.

Knives made of carbon steel are the sharpest.

The internal structure of the carbon steel Zen curver wheel is very simple, and when properly treated, it will perform extremely tough, with extremely high strength and hardness, excellent cutting performance, and good impact resistance. Fighting knives, survival knives, including household machetes, the most favored steel is carbon steel, which is tough and durable, can be sharpened very sharply, and is easy to polish, if it is blunt, re-sharpen it on the big bluestone, it will be as sharp as ever.

Other steels suitable for kitchen knives:

Manganese steel, also known as manganese alloy steel, is a high-strength steel, mainly used to withstand impact, extrusion, material wear and other harsh working conditions.

Tungsten steel (cemented carbide) has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, especially its high hardness and wear resistance, even at a temperature of 500, it remains basically unchanged, and it still has a high hardness at 1000.

High-carbon steel is often called tool steel, with a carbon content from to, which can be quenched and tempered. Hammers, crowbars, etc., are made of steel with carbon content; Cutting tools such as drills, taps, reamers, etc., are made of steel with a carbon content. <>
