Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel pipe fittings for industrial and high-temperature applications. Their Stainless Steel 348H Pipe Fittings are specifically engineered for environments requiring excellent creep strength, oxidation resistance, and corrosion protection at elevated temperatures. With high nickel and chromium content and controlled carbon levels, these fittings ensure long-term mechanical stability and durability. Manufactured under strict quality control, Walid Stainless delivers pipe fittings with precise dimensions, smooth finishes, and consistent performance. Customers rely on Stainless Steel 348H Pipe Fittings for secure, durable, and reliable connections in power plants, chemical industries, and high-temperature piping systems.
Stainless Steel 348H Pipe Fittings are made from an austenitic stainless steel alloy containing approximately 19–21% chromium, 32–35% nickel, and controlled carbon content to enhance high-temperature strength. This composition provides excellent resistance to oxidation, thermal fatigue, and stress corrosion cracking at temperatures up to 1100°C. The fittings typically exhibit tensile strength between 520–650 MPa and hardness around 160–190 HB. Their austenitic structure ensures superior toughness, dimensional stability, and mechanical reliability under continuous high-temperature and corrosive conditions.
