Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality stainless steel tubing for industrial and high-temperature applications. Their Stainless Steel 304H Tubing is specifically designed for elevated-temperature service, offering enhanced strength and creep resistance compared to standard 304. With slightly higher carbon content, it provides improved mechanical stability while retaining excellent corrosion resistance. Manufactured with precision and strict quality control, Walid Stainless ensures consistent dimensions, smooth finishes, and reliable performance. Customers rely on Stainless Steel 304H Tubing for long-term durability, safety, and dependable operation in heat-exposed industrial environments.
Stainless Steel 304H Tubing is an austenitic stainless steel alloy containing approximately 18–20% chromium, 8–10.5% nickel, and slightly higher carbon content than standard 304. This composition provides excellent resistance to oxidation and thermal fatigue, while the higher carbon content improves tensile and creep strength at elevated temperatures. The tubing typically exhibits tensile strength between 515–700 MPa and hardness around 160–190 HB. Its austenitic structure ensures excellent toughness, corrosion resistance, and dimensional stability under prolonged high-temperature service.
