B410LA steel is low carbon steel added with a little alloy elements such as niobium and/or titanium, which will be allowed to form carbide and nitride with carbon and nitrogen and separate these carbide and nitride out of ferritic matrix to increase steel strength. With excellent formability and relatively high strength, it is mainly used for manufacturing structural parts of automobiles such as chairs and cross beams.
B410LA steel product sizes:
Nominal thickness: 0.45mm~2.0mm, nominal width: 800mm~1850mm

Features
|
Relatively high-grade finishing surface
|
FB(O3)
|
It is allowed for the existence of a few surface defects which will not affect forming and coating & plating adhesiveness such as minor scratch, impression, pit, roll mark and oxidation tint.
|
High-grade finishing surface
|
FC(O4)
|
One side of relatively good quality is free any remarkable defect visible and the other side must reach FB requirements at leasts.
