Stainless Steel which is also known as inox steel offers some of the great and unmatched properties to the fabricated products. The alloy is an iron alloy having a little amount of chromium present (10.5%) and considerable amount of molybdenum. Stainless Steel can be used in the fabrication of various types of valves due to its high strength and great fabricability. This versatile material offers other resistive properties to the products. The grade is widely utilized in the manufacturing of the Needle and gauge valves.
About Stainless Steel 321:
Alloy 321 which is also known as UNS S32100 is known to be the most stabilized SS version that has some of the great advantages over any other grade. It has excellent resistance to intergranular corrosion, great resistance to high temperature and pitting resistance to chromium carbide precipitation at high temperature of approx 1500 Degree F. This titanium stabilized Austenitic SS has outstanding general corrosion and higher creep rupture properties than any other alloy grade. The grade offers good toughness to the products even in the low temperature environment.
About Stainless Steel 321H:
The Alloy 321H which is UNS S32109 has the higher carbon content in it that offers some of the excellent resistive properties. The grade was developed in order to enhance the creep resistance property, and high temperature approx 1000degree F. The carbon content in the grade helps in offering the best dual certifications. The hardening process involves the heat treatment which includes the cold working process.
