The Stainless Steel 347 Collars are crafted from a stabilized austenitic stainless steel alloy that includes chromium (17–20%), nickel (9–13%), and columbium (niobium). This unique composition boosts their resistance to intergranular corrosion and stress rupture at high temperatures. These collars boast impressive mechanical properties, with a tensile strength of around 75,000 psi (515 MPa) and a yield strength of about 30,000 psi (205 MPa), along with good elongation. Remarkably, these characteristics hold up even under high-temperature conditions. The niobium content helps stabilize the alloy during welding and thermal cycling, making Stainless Steel 347 collars a better choice than unstabilized stainless steels like 304 or 321 in heat-affected zones.
