Hot Rolled Automotive Steel

Hot Rolled automotive steel is mainly divided into automobile beam steel, automobile structural steel, automobile compartment steel automobile wheel steel, vehicle pipe structural steel, etc. After feedback from customers, Huaxiao’s products have a good cold working formability and can meet various processing requirements such as shearing, slitting and slitting, stamping, bending, roll welding, and so on.

As one of the few enterprises in China that can stably produce and supply extremely thin and wide specifications, we can stably supply the limit specifications of 1.2*1250mm,2.0*1610mm, and 3.0*1800mm with steel for car compartments, which is the first choice of lightweight materials for commercial vehicles.

Hot Rolled Automotive Steel Data Sheet

Main Automotive Steel Grades and Strength

Grade	Lower yield strength	Tensile strength	Elongation after fracture		Cold bending test	Low temperature impact test
	Rel MPa	Rm, MPa	A80%, h＜ 3.0mm	A%, h≥ 3.0mm	180°, b=35mm	Test temperature ℃	Impact-absorbing energy J
LG510L	≥355	510～ 650	≥20	≥24	d=0.5a，Qualified	–	–

LG700L	≥600	700～ 880	≥12	≥14	d=2a，Qualified	-20	≥34
LG750L	≥650	750～ 950	≥11	≥13	d=2a，Qualified	-20	≥34
LG800L	≥700	800～ 1000	≥10	≥12	d=2a，Qualified	-20	≥34
LG850LE	≥800	＞850	≥10	≥12	d=3a，Qualified	-40	≥27
LG980LE	≥900	≥980	–	≥12	d=4a，Qualified	-40	≥27
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 the tensile test sample is transverse, i.e.P5 sample according to GB/T 228. The direction of the bending sample is transverse, i.e the flapping test according to GB/T 232. the impact powder is longitudinal (i.e parallel to the rolling direction). 3）when the yield is not obvious, use Rp0.2 instead of ReL. 4)For steel with yield strength ≥600MPa, thickness higher than 8mm, the min yield strength can be reduced by 20MPa.

Common Structural Steel

Grade	Tensile strength, MPa	Elongation, %					180° Bending property
		L0=50mm					Longitudinal
		1.6mm	1.6-2.0	2.0-2.5	2.5-3.2	3.2	3.2	3.2
SPHC-PO	≥270	≥27	≥29	≥29	≥29	≥31	d=0a	d=1a
SPHD-PO	≥270	≥30	≥32	≥33	≥35	≥37	–	–
SPHE-PO	≥270	≥32	≥34	≥35	≥37	≥39	–	–
SPHF-PO	≥270	≥37	≥38	≥39	≥39	≥40	–	–
Note:the product should be used as soon as possible due to its aging effect.
a) Longitudinal sample should be used for tensile test, i.e P14 sample in GB/T 228.1;b)the property guarantee period is 6 months.
