High Strength Bake Hardening Steel Sheets and Coils
Bake hardening steel (BH steel) refers to a type of automotive steel that uses a specific chemical composition and production process to dissolve a certain amount of carbon atoms in the steel plate. The yield strength of steel plates is relatively low in the delivery state. If you want to increase its yield strength, you can paint and bake it after stamping. BH steel not only improves the dent resistance of automotive exterior panels, but also has good formability. Therefore, people usually use it to manufacture exterior panels such as car doors and engine hoods.

Application
Featured with improved pitting resistance and forming performance, BH steel has becamemore and more popular in auto parts like outer door sheets, engine cover, ete.
Production Line
Product Maintenance
We guarantee that there will be no tensile strain marks when using steel plates and strips under room temperature storage conditions for 3 months from the date of production. In addition, due to baking hardening, steel is more prone to tensile strain marks. Therefore, to ensure smooth use of the product, we strongly recommend that users use it as soon as possible.
