Teerasil Fittings and Plates is a leading Bangkok, Thailand-based manufacturer and supplier of high-performance piping products, such as **Stainless Steel 348H pipe fittings**. Engineered to withstand high-temperature and high-pressure use, 348H fittings provide superior resistance to oxidation and intergranular corrosion. The grade is a niobium-stabilized, high-carbon austenitic stainless steel intended for long-term exposure at elevated temperatures. Teerasil produces these fittings under international specifications such as ASTM A403 to provide consistent quality, accurate dimensions, and performance. These fittings are best suited for severe applications in power generation, chemical processing, petrochemical, and refinery services.

Stainless Steel 348H pipe fittings are produced from an austenitic stainless steel composition containing 17–20% chromium, 9–13% nickel, and a higher content of carbon (0.04–0.10%) than standard 348 with niobium (columbium) stabilization. This mixture increases the material’s thermal resistance and creep strength and avoids carbide precipitation on welding. The fittings also possess a tensile strength of around 515 MPa and a yield strength of 205 MPa. They resist corrosion and remain structurally stable at service temperatures of around 870°C and can be used in continuous high-heat environments.
