Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for B600L steel for car safety parts various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several B600L steel for car safety parts after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

B600L steel for car safety parts, Wear resistant steel plate has good wear resistance:
The chemical composition of the alloy wear-resistant layer is 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%. The macro hardness is HRC56-62 and the hardness of chromium carbide is HV1400-1800. Because the carbides are distributed perpendicularly in the direction of wear, even when compared with cast alloys of the same composition and hardness, the wear resistance is more than doubled.
