Stainless Steel 347 Fasteners play a crucial role in different types of applications, thanks to the unique properties of the 347 material. SS 347/347H is a columbium stabilized austenitic stainless steel grade that boasts excellent corrosion resistance properties. This grade demonstrates remarkable resistance to intergranular corrosion in carbide precipitation at high-temperature ranges, making it ideal for use in demanding environments.

Universe Metal & Alloy stands as a leading manufacturer and supplier of a wide range of Stainless Steel 347 Fasteners, Bolts and nuts in various dimensions, grades, and specifications. Whether it's standard or custom-made dimensions, our fasteners are precision-engineered to meet the highest quality standards. We ensure that each fastener is dimensionally accurate and compliant with both national and international quality standards.

Our SS 347/347H Fasteners are manufacturers and designed using high-quality alloy to ensure higher durability and ductility. The addition of a higher carbon amount in 347H enhances the sturdiness of the fasteners, making them suitable for use in critical applications. These fasteners exhibit outstanding strength and high performance, even in extreme conditions, with higher stress rupture and creep rupture strength up to 1500 degrees Fahrenheit temperature.

In addition to their exceptional mechanical properties, our Stainless Steel 347 Fasteners are easily formable and weldable, offering versatility in various fabrication processes. They can be hardened only by the cold working process, further enhancing their durability and longevity. With high tensile strength, excellent corrosion resistance, sturdiness, superior surface finish, and longer service life, our SS 347/347H Fasteners offer unparalleled performance in demanding applications.
