spec sm490 b steel

This will not be as easy as it looks. After a quick review of several papers; Here is the reported chemical composition ranges, which depend on product form and thickness; SM 490A,B, C, YA, YB (not sure if these are strength grades) Carbon content range 0.18% max, and for thicker grades 0.22% max Mn 1.60% max Si 0.55% max P 0.035% max S 0.035% max Note; other alloy elements may be added as necessary (Ni, Cr and Cu) The reported strength levels in one of the technical papers depended on product form; Yield Strength 3500-4030 kgf/cm 2 Ultimate Tensile Strength 5400-5720 kgf/cm 2 I would suggest you get your hands on JIS G3106-1992 or newer edition, Rolled Steel for Welded Structure for additional information on this material.1Shockdesigner331; You are in luck today. After I posted the above, I decided to check one other source on steel plates in my database. My steel plate source book from JFE indicates the SM 490 (490 N/ mm 2 class of steel plate and SM490Y are equivalent to the following ASTM Standards; SM490 ASTM A 572 SM490Y ASTM A 573 The tensile information above and the JIS G3106 still should be reviewed.Thanks Metengr!
