Regarding allowable stress

I need help. The client wants me to use a specific grade of stainless steel, 1Cr18Ni9Ti, but from what I’ve researched, this is a grade that has been phased out. I couldn’t find a replacement grade corresponding to this one. There is also no information on this grade in GB20801 and GB50316. Could someone help tell me which old standard specifies the allowable stress for this type of material?

You can find it by searching on Baidu; this is 321ss

1Cr18Ni9Ti is the chemical composition of 321; it is commonly known as 18-8. It is considered a discontinued material, and its replacement is S30408 (1Cr18Ni9)
