The composition of Stainless Steel 330 Bolts primarily includes chromium (19–23%), nickel (34–37%), and iron, with added copper and manganese to boost mechanical strength and oxidation resistance. This high-alloy makeup ensures excellent tensile and yield strength, along with remarkable creep and thermal resistance, making these bolts ideal for continuous high-temperature applications. On a mechanical level, 330 bolts exhibit good ductility, toughness, and stability, even under thermal cycling, pressure, and corrosive conditions.
Stainless Steel 321H Square Pipes offer excellent resistance to intergranular corrosion, especially in high-temperature applications. They typically come in sizes ranging from 20 mm to 200 mm on each side, providing robust structural support and versatility for various industries.
Known for its resistance to oxidation and corrosion, SS 321H Seamless Pipes are manufactured without welds or joints, offering uniformity and strength. They are available in 6 mm to 300 mm diameter and are suitable for high-pressure and high-temperature environments.
Featuring good resistance to corrosion and elevated temperatures, Stainless Steel 321H ERW (Electric Resistance Welded) Pipes are produced using electric resistance welding techniques. They are available from 15 mm to 150 mm, ideal for pipelines and structural applications.
SS 321H LSAW (Longitudinal Submerged Arc Welded) Pipes resist high-temperature oxidation and corrosion. These pipes are 60 mm to 1000 mm in diameter and are commonly used in oil and gas transmission and large-diameter piping systems.
