Marking of elbow material
Thread Content
On the drawings, some elbows are marked with the material specification A430.WP316L+G510. I know that it’s stainless steel, with grade 316L, but I’m not sure what all those additional specifications mean. Could someone explain it to me?
Is it related to the material and standards of stainless steel?
Ask the supplier. . . It seems to be of the urea grade
It is A403; WP stands for fitting, stainless steel； A234 WPB is a carbon steel pipe fitting
Learn*:victory:
The poster must have made a mistake; there are no A430s left. According to the pipe fittings, they should be of type A403, which are austenitic stainless steel fittings. WP316L is the grade designation; as for G510, I’m not sure what it means. Looking forward to an answer{:2_33:}
Stainless steel, high-pressure urea grade 316L+G510 is a special ultra-low carbon austenitic stainless steel. Its chemical composition is as follows: C 0.02, Si 0.36, Mn 1.58, Cr 17.23, Ni 13.57, Mo 2.51; C 0.06, P 0.016, S 0.0002, with the remainder being iron. Its tensile strength is greater than 550 MPa, its yield strength is greater than 300 MPa, and its elongation rate is 30%
