ASTM WK83762

Revision of A774/A774M-14(2019) Standard Specification for As-Welded Wrought Austenitic Stainless Steel Fittings for General Corrosive Service at Low and Moderate Temperatures


Table 4 Mechanical Test Requirements for 304L and 316L material list max tensile at 95 ksi. Raw material specification A240 does not have an upper limit and we regularly receive material above 95 ksi. Also in this table, 304L has a max Brinell hardness of 183 and Rockwell hardness of 88. A240 raw material is 201 and 92 respectively. We do on occasion see hardness below A240 limits but above A774 limits. I wish to harmonize A774 limits of these two alloys with A240, A403, A778, A312.
