Based in Chennai, India, Vinit Stainless is a reputable producer and supplier of high-end stainless steel goods. We are well-known for our dedication to quality and offer a wide range of industrial solutions designed to satisfy exacting industry requirements. Stainless Steel 347 Stud Bolts are unique among our products because of their exceptional strength, resistance to corrosion, and long-term durability. These bolts are perfect for use in the chemical, petrochemical, oil and gas, and power generation industries because they are made to withstand high temperatures and stress. At Vinit Stainless, our main goal is to provide dependable products that are supported by excellent customer service and prompt delivery.
The composition of stainless steel 347 Stud Bolts is 9–12% nickel, 17–19% chromium, and trace amounts of tantalum and niobium. Particularly in applications involving high temperatures, these stabilizing components improve resistance to intergranular corrosion. High tensile strength, good ductility, strong weldability, and resistance to oxidation and thermal fatigue are just a few of the alloy’s exceptional mechanical qualities. Because of these characteristics, SS 347 bolts can withstand harsh conditions like pressure, heat cycling, and chemical exposure. Under harsh operating conditions, the material guarantees structural integrity and long-term performance.
