What material is A8A in the American standards? Which domestic material does it correspond to? Thank you
I’ve heard of it for the first time; I’m not sure… Waiting for experts to answer
Haven’t heard of it. Could it be this grade: A8/T30108? Standard: ASTM A681-08. Chemical composition: Carbon C: 0.50–0.60; Manganese Mn: 0.20–0.50; Phosphorus P: ≤0.030; Sulfur S: ≤0.030; Silicon Si: 0.75–1.10; Chromium Cr: 4.75–5.50; Vanadium V: –; Tungsten W: 1.00–1.50; Molybdenum Mo: 1.15–1.65
Baidu couldn’t find it for you. Hehe!
