Stainless Steel 317/317L Round Bar
What is Stainless Steel 317/317L Round Bar
SS 317 is a higher strength steel grade which is constructed to represent a higher strength equivalent to the 316 grades. Otherwise, SS 317 Round Bars have chemical composition of chromium, molybdenum, and nickel as the primary composition that makes the material more resistant to corrosive media better than regular grades like 316. Due to the high percentage of ferrous into SS 317 grade bars, it is more durable than any other kind of grades more specifically like grade 304. SS 317 and 317L are almost equivalent grades with the only difference of carbon composition.
SS 317 round bars come into existence with low carbon version steel grade, better known for offering excellent resistance to corrosion and high strength properties. The industries that employ SS 317 and 317L are most often as textile industries, chemical industries, paper and pulp industries, etc.

Sumit Impex has been manufacturing and supplying high quality stainless steel 317/317L Round Bars. We provide all kinds of customized round bars according to different shapes, sizes, and dimensions of the customers. The SS forms of SS 317/317L which are offered by us are Round, square, rectangular, hydraulic, etc.
In terms of weldability, SS 317 performs very well. The hot working and cold working practices are performed by SS 317 and 317L. Although, SS 317 can be work hardened through cold workings that also helps out to increase the strength of the material and hence shows good versatility. During heat treating, temperature should be maintained up to 1700 Degree F. Dropping the temperature from the following range may cause some complications within the material grade.
