Alloy 321/321H Fasteners is a austenitic Stainless Steel, Titanium-Stabilized. It gives outstanding resistance to general corrosion and high resistance to intergranular corrosion when subjected to chloride carbide precipitation in the temperature range of 427-816°C. The alloy has oxidation resistance up to 816°C and has high creep and stress rupture properties with the addition of good low-temperature toughness. This means that alloy 321H is a higher carbon version, providing improved creep resistance and higher strength at high temperatures above 537°C.
Sankalp Alloys Overseas will manufacture excellent SS 321 / 321H Fasteners from 100% pure quality alloy sourced from reliable mills only. The manufacturing process is done under the proper guidance of a professional expert team; there is also a quality control team that keeps vigil to maintain the quality of the product. In addition to following the industry-set norms, adoption of the latest technology and use of modern tools shall be adopted for superior production.
