Characteristics and scope of application:
It is the most commonly used alloy structural steel, tensile strength, yield strength and hardenability than 40 steel is high, but the weldability is limited, with the tendency for crack formation. For tempering parts is important, such as working under alternating load parts, medium speed and medium load can be used for surface hardening parts. Load and high wear resistance, and no great impact on the parts, such as gear, sleeve, shaft, crankshaft, pin.

We also have a high quality logistics team who We keep more than 10,000 tons SCR440 steel plates in stock each month.we can meet our customer's any quantity request.Based on these stock source,our advantage industry spread into steel process like:cutting (any size and any shape) drilling, welding,milling,machining and steel structure.

We also have a high quality logistics team who make sure the fast delivery time and shipment.
