Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel fasteners. Their Stainless Steel 316H Nuts are designed for applications requiring high strength and excellent corrosion resistance at elevated temperatures. With slightly higher carbon content than 316L, these nuts provide improved creep resistance while maintaining toughness and corrosion protection. Manufactured under strict quality control, Walid Stainless ensures precise threading, smooth finishes, and reliable mechanical performance. Customers rely on Stainless Steel 316H Nuts for secure fastening, long-term durability, and dependable performance in chemical, marine, and high-temperature industrial environments.
Stainless Steel 316H Nuts are made from an austenitic stainless steel alloy containing approximately 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and slightly higher carbon content for enhanced high-temperature strength. This composition provides excellent resistance to oxidation, corrosion, and thermal fatigue. The nuts typically exhibit tensile strength between 515–650 MPa and hardness around 160–200 HB. Their austenitic structure ensures superior toughness, dimensional stability, and mechanical reliability under continuous high-temperature service, making them ideal for demanding industrial applications.
