When it comes to manufacturing of Valves, the manufacturer prefer using Stainless Steel and their grades as these offer some of the great characteristics to the fabricated valves. Stainless steel is also known as inox steel which is a alloy of iron that contains small amount of chromium, and molybdenum in it which offers ultimate resistance to corrosion and great strength to the valves. The industries prefer using SS 317 and 317L grade as they are best suited for the fabrication of different types of valves as they can withstand in high temperature and pressure situations.
About Stainless Steel 317-
SS 317 is known to be the modified version of the SS 316. The grade offers high strength and excellent fabricability to the formed valves. The grade offers ultimate resistance to corrosion and excellent general corrosive resistance in high temperature and pressure environment. The balanced chemical composition offers ultimate weldability and great durability to the fabricated valves. The chemical components includes Iron, chromium, molybdenum, nickel, manganese, silicon and other sulfur are some of the elements present that provides some of the great mechanical properties to the formed valves.
About Stainless Steel 317L-
SS 317L is a low carbon variant of 317 which has primarily molybdenum present in it. This austenitic SS offers improved resistance to corrosion, high pitting resistance to chloride ion solutions, and excellent crevice corrosion resistance at high temperature and pressure conditions. The resistive property of the grade increases as there is an increase in the molybdenum content. The 317L offers must greater resistance property to the grade as compared with other SS grades.
