These Stainless Steel 310/310S Seamless Pipes are manufactured from an austenitic alloy featuring approximately 24–26 % chromium and 19–22 % nickel. The main difference between the two grades is carbon content: 310 allows up to ~0.25 % C, while 310S limits carbon to ~0.08 % to reduce carbide precipitation and improve weldability. gneesteels.com+1 Typical mechanical values include a minimum tensile strength of ~515 MPa and yield strength of ~205 MPa, with elongation of 40 % or more. Kalpataru Piping Solutions+1 This material maintains its structural integrity in high‑temperature service and thermal cycling.
