309H

The chemical composition of 309H stainless steel round pipes is typically composed of iron (Fe) balance, chromium (Cr) 22–24%, nickel (Ni) 12–15%, molybdenum (Mo) 2–3%, manganese (Mn) 1%, silicon (Si) 0.75%, sulfur (S) 0.03%, phosphorus (P) 0.045%. It also contains traces of carbon, nitrogen, and other elements.

309H stainless steel round pipes are ideal for elevated temperature applications due to their high strength and excellent resistance to oxidation and corrosion. They are commonly used in boiler tubing, heat exchanger components, mechanical components such as valves and pumps, pressure piping, fuel lines, steam superheater tubes, and other applications. The properties of 309H stainless steel round pipes include high strength, excellent corrosion resistance at elevated temperatures, good deep drawing properties, and a smooth surface finish. It also exhibits good thermal conductivity and low thermal expansion.

FAQ's for Stainless Steel 309H Round Pipes

The Price Range For Stainless Steel 309H Round Pipes Products Is ₹250 To ₹350 Per Kilogram.

Yes, 309H stainless steel round pipes are relatively easy to fabricate when compared with austenitic or ferritic grades of stainless steels. It is weldable with conventional welding methods, although pre-heating may be required when welding thick sections. 

309H stainless steel round pipes can easily be polished to achieve a smooth, clean surface finish. It also has good deep drawing properties that allows it to form complex shapes and sizes without compromising its internal strength.
