We serve our customers with good quality products made from the best quality of raw materials that are available in the market.

These Stainless steel 321/ 321H valves are titanium stabilized austenitic stainless steel products which provides great imperviousness to general corrosion. These valves have high stress and creep rupture properties and resists oxidation at high temperatures. SS 321/ 321H valves are well-known for their great mechanical properties. They are highly ductile and can be hardened through work hardening.

Along with good resistance to corrosion, these valves also have excellent workability and welding-ability. These valves are quite versatile and are used in multiple industries. It is manufactured using high quality of raw materials which means product quality and durability will be flawless. These valves are known to be working very well in many temperature ranges. SS 321/ 321H valves have high corrosion and oxidation resistance due to nickel, chromium and titanium elements present in it. These valves are widely used in storage tanks, heat exchangers, pharmaceutical industry, biochemical industry, piping systems, etc.
