Renowned for providing premium stainless steel products that are suited to the exacting requirements of various industries, Vinit Stainless is a leading manufacturer and supplier with headquarters in Chennai, India. Stainless Steel 348 Nuts, which are renowned for their remarkable mechanical strength, heat resistance, and corrosion resistance, are one of our specialty products. These precisely designed fasteners are perfect for vital applications in the nuclear, chemical, power generation, and aerospace industries because they are made to meet international quality standards. Vinit Stainless stands out as a dependable and long-lasting partner for stainless steel solutions in India and abroad thanks to its dedication to customer satisfaction, prompt delivery, and value-added service.
About 18% chromium, 10% nickel, and a stabilized addition of columbium (niobium) and tantalum make up Stainless Steel 348 Nuts. These elements improve resistance to intergranular corrosion and stop carbide precipitation. At high temperatures, this austenitic stainless steel shows outstanding creep resistance, oxidation resistance, and mechanical strength. The nuts are perfect for high-stress and hot conditions because they have a tensile strength of about 550 MPa and good elongation and yield strength. Long-term performance under challenging circumstances, weldability, and dimensional accuracy are guaranteed by their metallurgical stability.
