Automotive Beam Steel

Auto beam series has been mainly used in stringer and transverse beam of automotive, it is the ealiest developed product in Guocheng, presently over one million tons have been put into market, of which LG510L and LG610L is a product awarded national metallurgy product quality certificate gold prize and LG510L is awarded metallurgic industry quality excellent product prize.

Note:1)a is the thickness of sample;b is the width of bending sample; d is the diameter of bending core. (2)The direction of tensile test sample is transverse, i.e.P5 sample according to GB/T 228. The direction of bending sample is transverse, i.e the flap test according to GB/T 232. the impact powder is in longitudinal (i.e parallel to the rolling direction).3）when the yield is not abvious,use Rp0.2 instead ReL.4)For steel with yield strength≥600MPa, thickness higher than 8mm, the min yield strength can be reduced by 20MPa.
