What is the difference between mild steel and medium carbon steel, and what is the difference betwee

Mild steel c% is to; Medium carbon steel c% is to; High carbon steel c% for.

Carbon in carbon steel is mainly in the form of Fe3C (i.e., cementite), and the amount of carbon content leads to the content and size of cementite. Fe has good plasticity but is soft; The cementite has poor plasticity but is hard. The carbon content is brittle and hard, but the plasticity is poor; It contains less carbon, has strong plastic toughness but low hardness.

This is the main difference between low-carbon steel and high-carbon steel, and it is also the reason for the other differences.

High-carbon steel has high hardness and low toughness; Mild steel has low hardness and high toughness.

No. 45 steel belongs to medium carbon steel, low carbon steel has strong plasticity and low strength, and is mostly used in structural bearing; Medium carbon steel is plastic, with moderate strength, and is used for mechanical transmission, gears, etc. High carbon steel has high strength and hardness, and is used for cutting tools, tool steel. There are many kinds of pattern steel processes, just by hand, there are many kinds of principles, but the basic principles of mechanical forging and manual should be the same.

The difference between low carbon and high carbon is that one is high hardness and low toughness, and the other is low hardness and high toughness. Good toughness is easy to bend and not easy to break.

I can't see it, I can't see it, and no matter how proficient I am, I can't see it without relying on instruments.

Say that the high carbon steel has low toughness to give me the wall, and the low carbon steel is also embarrassed to improve the toughness, are you tough, cutting a piece of wood can cut you down, can this be called toughness.

The differences between high-carbon steel and low-carbon steel are as follows:1. Toughness difference: the annealing structure of low carbon steel is ferrite and a small amount of pearlite, which has low strength and hardness, and good plasticity and toughness.

Therefore, its cold formability is good, and it can be cold formed by crimping, bending, stamping and other methods. After proper heat treatment or cold drawing hardening, high-carbon steel has high strength and hardness, high elastic limit and fatigue limit, and the cutting performance is acceptable, but the welding performance and cold plastic deformation ability are poor.

2. Application differences: low carbon steel has good weldability. Steel with carbon content from low carbon is easy to accept various processing such as forging, welding and cutting, and is commonly used in the manufacture of chains, rivets, bolts, shafts, etc.

High-carbon steel is mainly used to make springs and wear-resistant parts. Carbon tool steel is a high-carbon steel that basically does not add alloying elements, and it is also a steel grade with low cost, good cold and hot workability and a wide range of use in tool steel.

3. Different carbon content: low carbon steel is carbon steel with lower carbon content, which has lower strength and hardness, and better plasticity and toughness; High-carbon steel is often called tool steel, with carbon content from to, with high strength and hardness, high elastic limit and fatigue limit, and acceptable cutting performance, but poor welding performance and cold plastic deformation ability.

The differences are as follows:

Mild steel is carbon steel with lower carbon content, which is also known as mild steel because of its low strength, low hardness and softness.

Medium carbon steel is carbon steel with a carbon content. It includes most of the high-quality carbon structural steel and a part of the ordinary carbon structural steel. This type of steel is mostly used to make various mechanical parts, and some are used to make engineering structural parts.

High carbon steel, commonly known as tool steel, has a carbon content from to high, and 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 carbon content.

Custody and storage. 1. Choose a suitable site and warehouse.

2. The site or warehouse where the steel is stored should be selected in a clean and well-drained place, away from factories and mines that produce harmful gases or dust. Remove weeds and all debris on the site to keep the steel clean.

3. It is not allowed to be stacked together with acid, alkali, salt, cement and other materials that are corrosive to steel in the warehouse. Different varieties of steel should be stacked separately to prevent confusion and prevent contact corrosion.

4. Large section steel, rails, steel plates, large-diameter steel pipes, forgings, etc. can be stacked in the open air.

5. Small and medium-sized steels, wire rods, steel bars, medium-caliber steel pipes, steel wires and wire ropes, etc., can be stored in well-ventilated sheds, but they must be padded on and underneath.

6. Some small steels, thin steel plates, steel strips, silicon steel sheets, small-diameter or thin-walled steel pipes, various cold-rolled and cold-drawn steels and high-quality, corrosive metal products can be stored in storage.

7. The warehouse should be selected according to the geographical conditions, and the ordinary closed warehouse is generally adopted, that is, the warehouse with a roof with walls, tight doors and windows, and a ventilation device.

8. The warehouse requires ventilation on sunny days, and moisture-proof on rainy days, and always maintains a suitable storage environment.

High-carbon steel is often referred to as tool steel.

The carbon content ranges from to, and 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 carbon content.

to the manufacture of steel.

Mild steel (mild

steel) is a carbon steel with a lower carbon content, which is also known as mild steel because of its low strength, low hardness and softness. It includes most of the ordinary carbon structural steel and some high-quality carbon structural steel, most of which are used for engineering structural parts without heat treatment, and some are used for mechanical parts that require wear resistance after carburizing and other heat treatments.

Further information: Carbon steel is an iron-carbon alloy with a carbon content. It is also called carbon steel. Generally, it also contains small amounts of silicon, manganese, sulfur and phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the plasticity is lower.

The carbon content of low carbon steel (AISI1005 1026) is, the manganese content is, the phosphorus content does not exceed, and the sulfur content does not exceed.

The carbon content of medium carbon steel (AISI1029 1053) is, the manganese content is, the phosphorus content does not exceed, and the sulfur content does not exceed.

The carbon content of high-carbon steel (AISI1055 1095) is, the manganese content is, the phosphorus content does not exceed, and the sulfur content does not exceed.

The difference between low-carbon, medium-carbon, and high-carbon steel is how much carbon is there. Low-carbon steel is a carbon steel with low carbon content, medium carbon steel with a carbon content of stupid, and high-carbon steel is also called tool steel, with a carbon content of.

Carbon steel is an iron-carbon alloy with carbon content, also known as carbon steel, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength.

Carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus, and the greater the hardness, the lower the plasticity of the carbon sail round bar, and the plasticity and ductility of low carbon steel are very good.

Carbon steel can be divided into three types according to its use: carbon structural steel, carbon tool steel, and free-cutting structural steel, of which carbon structural steel is divided into two types: engineering construction steel and machine manufacturing structural steel.
