Product Description

 

Product Description

1. 316 Stainless Steel
Composition: Contains chromium, nickel, and molybdenum.
Properties: Known for its excellent corrosion resistance, especially against chlorides and other aggressive environments.
Uses: 316 stainless steel pipes are extensively used in marine environments, chemical processing, and other industries where higher resistance to corrosion is required.
2. 304 Stainless Steel
Composition: Comprised of chromium and nickel.
Properties: Balances corrosion resistance with strength and is highly formable and weldable.
Uses: 304 stainless steel pipes are common in food processing, pharmaceuticals, and any applications requiring corrosion resistance and cleanliness.
3. 309 Stainless Steel
Composition: Higher chromium and nickel content than 304.
Properties: Excellent resistance to oxidation and can withstand high temperatures without corroding.
Uses: Ideal for high-temperature applications such as heat exchangers, furnace parts, and firebox sheets.
4. 347 Stainless Steel
Composition: Similar to 304 but includes columbium (niobium) for stabilization.
Properties: Excellent resistance to intergranular corrosion and maintains good mechanical properties at high temperatures.
Uses: Used in high-temperature applications like aircraft exhaust stacks, manifolds, and chemical production equipment where intermittent heating and cooling cycles are expected.
Industrial welded pipes made from these stainless steel grades are crucial in environments that require durability, resistance to corrosion, and stability under high temperatures. They are vital components in a wide range of industrial applications, ensuring the safe and efficient transport of liquids, gases, and chemicals under various conditions.
