The Stainless Steel 348/348H Forged Fittings are primarily made up of chromium (17–20%), nickel (8–12%), and columbium (niobium) to enhance stabilization. The ‘H’ variant features a higher carbon content, which boosts its high-temperature strength. These fittings boast impressive mechanical properties, including a tensile strength of around 515 MPa, a yield strength of about 205 MPa, and an elongation of 35%. They also provide outstanding resistance to intergranular corrosion and stress cracking. With their high creep and rupture strength, Stainless Steel 348/348H is perfectly suited for elevated temperature service in demanding environments, ensuring a long service life and maintaining structural integrity.
