Stainless Steel 347 Fasteners
Vision Alloys is a leading SS 347 fastener manufacturer and a trusted stainless steel 347H nut bolt supplier in India. We provide a diverse selection of 347 stainless steel fasteners, such as nuts, bolts, washers, screws, and studs, all crafted for high-performance use. Our Stainless Steel 347H fasteners are recognized for their outstanding corrosion resistance, impressive high-temperature strength, and long-lasting durability. These fasteners meet international quality standards and are commonly used in the aerospace, power generation, and chemical processing industries.
Stable austenitic stainless steel alloys containing 17–20% chromium, 9–13% nickel, and columbium (niobium) make up the SS 347 and 347H fasteners. This helps them resist intergranular corrosion better. The 347H grade features a higher carbon content, which enhances its strength in high-temperature settings, reaching up to 1000°C. These 347 stainless steel bolts, nuts, and washers are perfect for resisting oxidation in tough industrial environments.
We manufacture 347 stainless steel nuts and bolts using premium raw materials, ensuring superior mechanical and corrosion-resistant properties. The alloy's ingredients—chromium, nickel, columbium, carbon, manganese, silicon, and phosphorus—make it very resistant to cracking, stress corrosion, crevice corrosion, and pitting. These fasteners are perfect for heat exchangers, furnace components, and refinery equipment.
