Product Inquiry

Product Introduction:

Automotive wheel steel is one of the most important parts in automobiles, with complex deformation during the manufacturing, which not only need to satisfy technology requirements, but also meet the process requirements of mass production. Therefore, the requirement on automotive wheel steel is stringent. LY Steel guarantees product microstructure and property with high strength, formability, good fatigue performance and welding performance through clean steel metallurgy, TMCP technology and Ca treatment patent technology.

Delivery standard refers to Q/OHAC810 Sheet and Strip for Automotive Wheel Structure

Mechanical Property:

Steel grades	Tensile strength, MPa	Yield strength, MPa	Elongation		Cold bending
Steel grades	Tensile strength, MPa	Yield strength, MPa	A_80mm(%), h＜3.0mm	A%,h≥3.0mm	180°, b=35mm
LG330CL/RCL330	330–430	≥225	≥27	≥33	d=0.5a
LG380CL/RCL380	380–480	≥235	≥23	≥28	d=0.5a
LG420CL/RCL420	420–520	≥275	≥23	≥28	d= 1a
LG490CL/RCL490	490–610	≥325	≥20	≥24	d=a
LG510CL/RCL510	510–630	≥355	≥20	≥24	d= 1.5a
LG540CL/RCL540	530–650	≥355	≥18	≥22	d= 1.5a
LG590CL/RCL590	590 to 710	≥420	≥17	≥20	d=2.0a
LG650CL	650 to 770	≥500	≥15	≥ 18	d=2.0a
Remark:1.a is thickness of the sample, b is width of the cold bending sample, d is bending diameter.2）The direction of the tensile sample is transverse, i.e.P10 sample in GB/T 228. The direction of the cold bending sample is transverse, i.e. GB/T 232 flap type test.
