Stainless Steel 321H Screw

321H Stainless Steel Screws have a chemical composition containing iron, chromium, nickel, and titanium. Chromium provides a strong corrosion resistance when combined with the alloy’s high nickel content, while titanium improves its strength at higher temperatures. Adding further molybdenum increases the corrosion resistance and stability of 321H stainless steel screws compared to other stainless steel. It is non-magnetic and allows easy welding and forming without losing any of its excellent properties.

SS 321H screws are used in various industries due to their robust properties, high-temperature strength, and corrosion resistance. Its high chromium content provides excellent corrosion protection under normal conditions and in highly-corrosive environments such as those with high chloride concentrations. Furthermore, the titanium alloying element allows for increased strength at elevated temperatures, making it ideal for thermal shock stability applications. Adding molybdenum further enhances these properties, while its low carbon content ensures minimal carbide precipitation during welding. This combination of attributes makes stainless steel 321H screws highly versatile and suitable for numerous applications where strength and corrosion protection are necessary.
