There are many kinds of high strength cold-rolled steel plates, which are usually distinguished by mechanical properties such as tensile strength, tensile strength, elongation, etc. The addition of elements for Mn, Si, Nb, V, N has a greater impact. Because the strength of high strength cold rolled steel is much higher than that of ordinary carbon steel, for the same load, a smaller section can be used, and the overall weight can be reduced. It is mainly used to produce high strength products such as automotive structural parts.

Longcheng thin plate high strength alloy steel representative brand has 20 #, 35 #, 45 #, 50 #, 16Mn, Q345, SAPH series/SPFC series, etc., the execution standard has GB/T 13237-91 high quality carbon structure steel cold-rolled sheet steel and steel strip, GB/t1591-2008 low alloy high strength steel and other national standards.

The main terminal products are structural parts for vehicles, hardware products, agricultural and forestry tools, military products, etc.
