Q: Can you tell me how the mechanical properties of C276 compare to the A4 stainless?
A: That would depend on the grade of A4 you are talking about but as a rough comparison Hastelloy C276 bolts per ASTM B564 would have a MIN Tensile of 100ksi and a MIN Yield of 41KSI. A4-70 has a min yield of 101 KSI and a yield of 65 KS.
