Stainless Steel 347 Hollow Bar is an austenitic stainless steel that’s stabilized with columbium (niobium), which boosts its resistance to intergranular corrosion. Its typical chemical makeup consists of 17–19% chromium, 9–13% nickel, along with trace amounts of columbium and tantalum. This material boasts impressive mechanical properties, featuring a tensile strength of about 515 MPa, yield strength of 205 MPa, and an elongation of 40%. It retains its mechanical integrity even at high temperatures, making it a great choice for applications that involve heat. Additionally, this stainless steel grade offers good resistance to creep and stress-rupture, particularly in oxidizing conditions.
