Hi All, When I read ASME II Part A I see in SA182 have mentioned about 316L and also in SA403 mention about 316L, so what is diffirent between these Steel?
They are for different product forms. SA182 addresses forged fittings and SA403 addresses wrought (hot or cold formed) fittings. Wrought fittings may be seamless or welded, forged fittings are not seam welded.
