(S)A283 Grade A, (S)A283 Grade B carbon steel plate

Source:Yusheng steel

Carbon steel plate A283 Grade A and A283 Grade B under steel specification ASTM A283/A283 M,they are equal to carbon steel plate SA283 Grade A and SA283 Grade B in steel standard ASME SA 283/SA 283M.Considering the different carbon contains,there are a little difference in yield strength between A283 Grade A and A283 Grade B.For structural steel A283 Grade A,the minimum yield strength is 165 Mpa,tensile between 310 and 415.And for carbon steel sheet A283 Grade B,the yield strength shall be above 185 Mpa,tensile strength within 345 to 450 Mpa.

 

These common carbon structural steel plate A283 Grade A and A283 Grade B are mainly used to built steel tanks in oil plants and companies.Now YUSHENG STEEL can offer steel grade A283 Grade A and A283 Grade B thickness reach up to 600 mm,it is top in China,even in the whole world and also can keep the better steel properity at the same time.
