Universe Metal & Alloy is a reputable name in the industry, recognized as manufacturers, suppliers, stockists, and exporters of Stainless Steel 321H Fasteners. Our extensive range of fasteners includes bolts, nuts, screws, dowel pins, threaded rods, and more, all meticulously crafted from premium-grade 321H material. These fasteners are engineered to meet the diverse needs of various applications, offering exceptional performance, durability, and reliability.

Stainless Steel 321H Fasteners play a crucial role in different types of applications, thanks to the unique properties of the 321H material. Unlike standard austenitic stainless steels, 321H stainless steel is a stabilized variant, offering improved resistance to sensitization and intergranular corrosion at higher temperatures. With a composition comprising 17% chromium, 9% nickel, and titanium for stabilization, along with carbon, iron, manganese, nitrogen, phosphorus, sulfur, and silicon, 321H stainless steel delivers superior mechanical and corrosion-resistant properties.

Universe Metal & Alloy stands as a leading manufacturers and suppliers of a wide range of Stainless Steel 321H Fasteners, Bolts and nuts in various dimensions, grades, and specifications. Whether it's high-temperature, high-pressure, or corrosive environments, our fasteners are engineered to withstand the toughest conditions. The SS 321H Hex Bolt, for instance, boasts a minimum tensile strength of 621MPa, a minimum yield strength of 276MPa, and a high hardness of 80 HBW, ensuring exceptional performance and longevity.

The AISI 321H Nut Bolt is particularly well-suited for use in high-temperature and high-pressure applications, thanks to its high melting point and superior mechanical properties. Additionally, the different types of UNS S32100 321H Stainless Steel Dowel Pins offer excellent temperature resistance, withstanding temperatures of up to 1399 degrees Celsius based on the composition mixture.

One of the key advantages of 321H stainless steel is its improved weldability compared to other stainless steel grades, such as 304, thanks to the addition of titanium. This makes the material ideal for welding procedures, ensuring reliable and durable joints in various applications. Moreover, the 321H Stainless Steel Threaded Rod can be used under elevated temperatures of up to 816 degrees Celsius, further highlighting its versatility and reliability.

Our range of Stainless Steel 321H Fasteners Exporters, including SS 321H Screw, exhibits high oxidation resistance and corrosion resistance, making them suitable for demanding environments where exposure to harsh chemicals and extreme temperatures is common.
