Stainless Steel 317 features

 

317 stainless steel is a type of austenitic stainless steel, which contains a low to moderate amount of carbon content. It also has an enhanced corrosion resistance compared to other types of stainless steel. This makes it particularly desirable for use in industrial and commercial applications, as it is able to withstand harsh environmental conditions with ease.

 

317 stainless steel is an alloy made up of iron, chromium, nickel and molybdenum. The chromium content provides the metal with its anti-corrosive properties, while the molybdenum further strengthens the alloy's ability to resist corrosion in certain environments. The nickel content adds further strength and corrosion resistance while ensuring that the metal remains ductile even at cryogenic temperatures.
