SS 321 Stud bolts feature excellent mechanical properties including density 8.0 g/cm^3, melting point equals to 1454 degree celsius, tensile strength 75000 Mpa, Yield strength up to 205 Mpa, and 35% of elongation. SS 321 Stud bolts are available in SS 321 screws, SS 321 anchor bolts, SS 321 nuts, etc.
SS 321 Stud bolts can be mechanically hardened or fastened through clamping temporarily or permanently. They are so freely removed and can be fit easily without any troubles. SS 321 Stud bolts are applicable across high temperature environments, usually oil and gas industries. Alloy 321H stud bolts is a high carbon version alloy that may contain carbon up to 0.1% than Alloy 321. Alloy 321H is usually demanded by the chemical processing, welding equipment, like others. SS 321H double ended studs are low temperature durable alloy. SS 321h threaded rods are almost the same as SS 304, but stabilized by addition of titanium and nickel contents. Apart from SS 321 Stud bolts, Jfeidia also supplies different forms such as bolts, washers, screws, and nuts.
