What’s A653 BHS steel ?

ASK:

What's A653 BHS steel ?

ANSWER:A653 BHS is a steel grade in American standard ASTM A653/A653M, A653 BHS is bake hardenable quality steel material, which has six grades: Grade 26(180), Grade 31(210), grade 35(240), grade 41(280), grade 44(300).ASTM A653/A653M specification covers steel sheet, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot-dip process in coils and cut lengths.

A653 BHS material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.

A653 BHS steel Coil/strip/sheet surface quality:
A (As coated surface), B (Improved surface),C (Best quality surface)

A653 BHS steel Coil/strip/sheet surface treatment:
Chemical treated or not chemical treated, Oiled or not oiled, Phosphatized or not Phosphatized.

A653 BHS steel Coil/strip/sheet coating mass:
Pure Zinc coating: G01(Z001), G30(Z90), G40(Z120), G60(Z180), G90(Z275), G100(Z305), G115(Z350), G140(Z450), G165(Z500), G185(Z550), G210(Z600), G235(Z700), G300(Z900), G360(Z1100)
Alloy Zinc+Fe: A01(ZF001), A25(ZF75), A40(ZF120), A60(ZF180)

A653 BHS steel yield strength :
Grade 26(180) should be not less than 180MPa

Grade 35(240) should be not less than 240MPa
Grade 41(280) should be not less than 280MPa
Grade 44(300) should be not less than 300MPa
A653 BHS steel tensile strength :
Grade 26(180) should be not less than 300MPa
Grade 31(210) should be not less than 320MPa
Grade 35(240) should be not less than 340MPa
Grade 41(280) should be not less than 370MPa
Grade 44(300) should be not less than 390MPa
A653 BHS steel Elongation in 50mm
Grade 26(180) should be not less than 30%
Grade 31(210) should be not less than 28%
Grade 35(240) should be not less than 24%
Grade 41(280) should be not less than 22%
Grade 44(300) should be not less than 20%

Bake hardening :
All the grades should be 4(25)-3(20)
