The Stainless Steel 422 Stud Bolts are made from a martensitic stainless steel alloy that contains about 11–13% chromium, along with added molybdenum and vanadium to boost strength and creep resistance. This unique composition ensures good oxidation and corrosion resistance even at high temperatures. Their mechanical properties include impressive tensile and yield strength, excellent hardness post-heat treatment, good fatigue resistance, and stability under thermal stress. These stud bolts maintain their mechanical integrity and load-bearing capacity in high-pressure and high-temperature settings.
