Which is harder or stainless steel and is more suitable for making knives

Carbon steel knives are more suitable for cutting edges.

And it's sharper. The carbon content should be around the center, not too high and too low.

Carbon steel in heat treatment.

In a good case, it can be sharpened extremely sharp. And many stainless steels, such as 440C, cannot reach the sharpness of carbon steel no matter how they are grinded.

The reason is in the microstructure. Both carbon steel and stainless steel can reach a level of hardness, but hardness alone is not enough.

Some people mention self-sharpening, which is actually the property of small chipping that improves the cutting ability of carbon steel.

Stainless steel, on the other hand, can be bent rather than collapsed at a very thin microscopic edge position, although it can be treated with high hardness. Once the heat treatment reaches the point where the cutting edge of the microscopic upper edge collapses, the structural strength of the entire knife may become extremely poor and easy to break. The carbon steel knife is microscopicly disintegrated at the cutting edge, but the overall strength can be ensured.

To put it simply, stainless steel is hard and sticky, while carbon steel is hard and brittle with good elasticity.

There are many carbon steel models, sharpness is not absolute, 440C-440A in stainless steel is also a good material, these two are not black iron can be compared, first of all, iron is definitely not sharp, because pig iron is simply too hard and the toughness is insufficient, so the knife must be made of steel, as for you to take into account the hardness and sharpness If it is not a composite estimate, it is difficult to meet your requirements, you can check the knife of a compound forging, and the composite knife such as the three pieces can probably meet your requirements.

If it is fast, it must be that the scissors of high-carbon steel are fast, but they are easy to rust, and the scissors of stainless steel are not easy to rust.

Stainless steel is not easy to rust, if it is martensitic, the quenching edge can also be used, but it will rust after a long time. The strength and hardness of high-carbon steel can be faster, but no matter how bad it is, it is easy to rust, in fact, no matter what steel is used up, you can put some oil on it. Carbon steel knives are harder than stainless steel and are easier to be sharpened, and carbon steel scissors are easy to rust but durable enough to be unsightly.

Stainless steel scissors are not rusty and beautiful, but the hardness is not enough and it is easy to be blunt. Most stainless steel is suitable for short knives, and most carbon steel is suitable for long knives.

Hope mine is helpful to you.

Hello dear<>

We are happy to serve you, and the answers are <> below

Which is better for kitchen knives between high-carbon steel and 400 stainless steel, the answer is as follows; Carbon steel kitchen knives are good, 4oo stainless steel hardness is not enough and wonton mouth 1, different compositions, high-quality stainless steel knives contain more active metals in addition to iron, so they can prevent rust; High-carbon steel knives contain a lot of carbon and less reactive metal. 2. When the chromium content is greater than 12%, a layer of oxide film will be formed on the surface of stainless steel, commonly known as passivation film, with this layer of oxide film will not be easy to dissolve in some media, which plays a good isolation role and has strong corrosion resistance; 1. When the mass fraction of carbon of high-carbon steel is larger, the hardening and crack sensitivity tendency after welding is greater, so the weldability is extremely poor, and it cannot be used to manufacture welded sail structure. It is often used to manufacture components and parts that require more hardness or wear resistance, and its welding work is mainly weld repair.

2. Since the tensile strength of high-carbon steel is mostly above 675MPa, the commonly used electrode models are E7015 and E6015, and E5016 and E5015 electrodes can be selected when the component structure is not high. In addition, chromium-nickel austenitic steel electrodes can also be used for welding. 3. The carbon content of high-carbon steel is higher than that of the poor chain, and the weldability is relatively poor, so it should be preheated during welding, and it should be cooled slowly or 350 degrees of low-temperature tempering treatment after welding, and the specific length of heat treatment time is determined by the thickness of the workpiece.

If it cannot be preheated, it is necessary to use welding materials with good welding performance and crack resistance, but the welding speed must be reduced.

Carbon steel is better than stainless steel.

Generally speaking, carbon steel does not have special alloying elements added, while stainless steel adds a high alloy content in order to prevent rust. These two steels are used differently and cannot be compared. Carbon steel is generally stronger than stainless steel, but it rusts easily.

Stainless steel is characterized by a thin and dense chromium-rich oxide film on the surface of stainless steel, which makes stainless steel water pipes have good corrosion resistance in all water quality, including soft water, even when used underground. Stainless steel can work safely for a long time at temperatures of -270°C-400°C, and it will not be harmful at high or low temperatures. Carbon steel is an iron-carbon alloy with a carbon content of less than WC.

Also called carbon steel. It also contains small amounts of silicon, manganese, sulfur, and phosphorus.

Difference Between Carbon Steel and Stainless Steel:

1. Although there are iron elements in carbon steel and stainless steel, and iron is relatively easy to oxidize, the corrosion resistance of welding iron materials is relatively poor, but in addition to iron, chromium is also added to stainless steel, which can effectively increase the corrosion resistance of the material, so in contrast, the corrosion resistance of stainless steel is stronger.

2. Ductility is different, carbon steel and stainless steel have a certain degree of ductility, but because stainless steel contains a large amount of nickel elements, which can effectively improve the ductility of the product, the ductility of stainless steel will also be better than carbon steel. In addition, for ductility, it refers to the degree to which the material can be pressed, and the better the ductility, the thinner the material can be pressed. <>

Summary. Carbon steel is durable. When it comes to durability, both carbon steel and stainless steel are very durable.

However, the biggest difference is in abrasion and corrosion resistance. Due to its high chromium content, stainless steel does not rust but wears out quickly when used in wear equipment. Carbon steel is stronger and more durable and may not wear easily, but it can corrode and rust when exposed to moisture.

Steel (carbon steel) and stainless steel are both essential metal materials in most metal industries. To understand the various metalworking processes and parts, it is crucial to distinguish between the two.

I want to buy a small pair of scissors, do you recommend buying carbon steel or stainless steel.

The kitchen is best made of stainless steel, and cutting flowers and grass, cutting cloth can be a variety of options, using carbon steel is more profitable and durable, but easy to rust, so it is recommended to use scissors with anti-rust treatment.

<> front steel, also known as high-speed steel or white steel, has the characteristics of high hardness, high wear resistance and high heat resistance.

Carbon steel is just an alloy of iron and carbon, and its performance characteristics are that with the change of carbon content, the carbon content is high, the hardness increases, and the toughness decreases, and the carbon content is low, the hardness decreases, and the toughness increases.

Of course, it is better to use high-speed steel to make knives, which is both sharp and not too rusty, and the hardness is also very high.

High-speed steel, also known as wind steel or edge steel, means that it hardens even when cooled in air during quenching, and is sharp. It is a complex alloy steel containing carbide-forming elements such as tungsten, molybdenum, chromium, vanadium, etc.

Carbon steel is an iron-carbon alloy with a carbon content of 0.02 to 2 percent, also known as carbon steel.
