Our SS 321H Fasteners, featuring an alloy with carbon content ranging from 0.04% to 0.10%, offer remarkable oxidation resistance at temperatures up to 1500 degrees Fahrenheit (816 degrees Celsius). Notably, this alloy exhibits superior creep and stress properties compared to alloys 304 and 304L, along with excellent low-temperature tolerance.

The key distinction between these grades lies in their carbon composition. While SS 321 has a maximum carbon cap of 0.8%, SS 321H boasts a higher carbon content, ranging from 0.4% to 0.1%, granting it enhanced strength to withstand elevated temperatures and improved creep resistance. At Siddhgiri Tubes, we take pride in our role as a leading manufacturer and supplier of Stainless Steel 321 and 321H Fasteners. Our team of seasoned professionals ensures that only the finest raw materials are utilized, maintaining the exceptional quality of our fasteners.

Crafted from titanium-stabilized alloy, our Stainless Steel 321/321H Fasteners exhibit exceptional strength, scaling resistance, phase stability, and aqueous corrosion resistance. For applications necessitating resistance to intergranular corrosion post-welding, 304L fasteners may be preferred; however, if working temperatures surpass 932°F, the superior heat strength of 321 sheets makes them the ideal choice.
