The meaning of HC180B

HC180B is a specific grade of bake-hardening steel that is commonly used in the automotive industry. The “HC” in the grade name stands for “high-strength, cold-rolled” steel. The “180” in the grade name refers to the minimum yield strength of the steel, which is 180 megapascals (MPa). The “B” at the end of the grade name indicates that the steel has been bake-hardened, which means that it has been processed to increase its strength through age hardening.

What is Bake Hardening Steel?

Bake-hardened steel is a type of steel that is specifically designed for use in automotive outer coverings. It is made by retaining a certain amount of solid solution carbon and nitrogen atoms in the steel during production. Additionally, strengthening elements such as phosphorus and manganese are added to further increase its strength.

After the steel is processed and formed into its final shape, it is baked at a certain temperature. This process is known as age hardening, and it serves to increase the yield strength of the steel. Age hardening occurs because the retained carbon and nitrogen atoms form clusters within the steel during the baking process, which in turn strengthens the steel.

The organization of bake-hardened steel is primarily ferrite. Ferrite is a type of iron crystal structure that is known for its softness and ductility. By adding strengthening elements and utilizing age hardening, however, the strength of the ferrite can be greatly increased, making it suitable for use in automotive outer coverings.
