Nial Sheets and Plates is your go-to manufacturer and supplier of Stainless Steel 347 Angles right here in Houston, USA. They specialize in crafting high-quality structural components that are built to last, offering strength, durability, and resistance to corrosion, especially in high-temperature settings. Stainless Steel 347 is a stabilized austenitic stainless steel alloy, enhanced with columbium (niobium) to boost its resistance to intergranular corrosion after welding. Nial produces these 347 Angles in line with international standards, catering to various industries like aerospace, power generation, chemical processing, and food manufacturing. These angles are perfect for structural applications that require both mechanical strength and thermal stability.
When it comes to composition, Stainless Steel 347 Angles mainly consist of chromium (17–20%), nickel (9–13%), and columbium/tantalum for stabilization, along with small amounts of carbon, manganese, and silicon. This alloy boasts impressive mechanical properties, featuring a tensile strength ranging from 515 to 750 MPa and a yield strength of about 205 MPa, along with good elongation and toughness. It effectively resists intergranular corrosion, particularly after welding, and maintains its strength even in elevated temperatures, making it an excellent choice for stress-bearing structures that face heat and corrosive environments.
