Carbon Steel in the Automotive Industry

1. Carbon steel for automobile industry

Carbon steel is one of the most important materials used in the automotive industry. It is widely used in the manufacture of bodywork, engines and other components. The main reasons for its widespread use are its good strength-to-weight ratio, high durability, and low cost.

In recent years, however, the use of carbon steel in cars has been declining due to the increasing use of lighter-weight materials such as aluminum and plastics. The trend is likely to continue as automakers seek to reduce vehicle weight to improve fuel efficiency and emissions levels.

What are the advantages of high -carbon steel?

1.High -carbon steel heat treatment can obtain high hardness (HRC60 1: 65) and better abrasion resistance.

2.High -carbon steel has better cutability.

3.The raw materials are easy to obtain, and the production cost is low.

What are the disadvantages of high -carbon steel?

1. It has poor thermal hardness. When the operating temperature of the tool is greater than 200 ° C, its hardness and abrasion resistance will decrease.

2. It has low quenchtability.

The difference between high -carbon steel and low -carbon steel is as follows:

1. Differences of toughness: Low -carbon steel annealing tissue is iron and small amount of pearl light. Its strength and hardness are low, and the plasticity and toughness are better. Therefore, its cold formability is good. High -carbon steel has a high strength and hardness, high elasticity and fatigue limit after proper heat treatment or cold pull -out hardening, 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 welding. Carbon content from 0.10%to 0.30%Low -carbon steel is easy to receive various processing such as forging, welding and cutting, and is often used for manufacturing chains, rivets, bolts, shafts, etc. High -carbon steel is mainly used to make spring and wear -resistant parts. Carbon tool steel is a high -carbon steel that basically does not add alloy elements. It is also a steel species with low cost, good hot and cold processing, and wide range of use of tool steel.
3. Different carbon content: Low -carbon steel is carbon steel with carbon content below 0.25%. Its strength and hardness are low, and plasticity and toughness are better. 1.70%, the strength and hardness of bribery, high elasticity and fatigue limit, cutting performance is acceptable, but the welding performance and cold plastic deformation ability are poor.

Our advantage

Product Inventory

Jiangsu Jinruiheng uses standard export transportation packaging, according to the size of the stainless steel plate binding steel belt. According to our shipping experience, a 20-foot container can hold 22 tons of stainless steel, and a 40-foot container can hold 25 tons of stainless steel. For larger orders, we ship by bulk carrier, which is cheaper. Packaging can also be customized according to customer needs.
