Maria Pipes and Tubes, Kuala Lumpur, Malaysia is a trusted manufacturer and supplier of **Stainless Steel 316H Welded Pipes**, providing high-quality piping solutions for heightened temperature and high-pressure conditions. Stainless Steel 316H is an elevated-carbon form of 316, designed particularly to offer enhanced strength and creep resistance at temperatures above 500°C. Our welded pipes are made from high-grade materials and state-of-the-art welding processes to provide strength, precision dimensioning, and long-term performance. Operating in sectors including power generation, petrochemicals, and oil and gas, Maria Pipes and Tubes provides consistent solutions that adhere to international standards.
**Stainless Steel 316H Welded Pipes** consist of 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and higher carbon content (0.04–0.10%) for reinforcing high-temperature strength. These pipes provide a tensile strength of around 515 MPa, yield strength of 205 MPa, and elongation of 35%. Welded form enables cost-effective production at higher diameters while retaining outstanding corrosion resistance and mechanical properties. 316H also provides good resistance to pitting and crevice corrosion, particularly in chloride environments and acidic mediums.
