317 Stainless Steel

Stainless steels are known as high-alloy steels. They consist about 4-30% of chromium. They are classified into martensitic, austenitic, and ferritic steels based on their crystalline structure.
Grade 317 stainless steel is a modified version of 316 stainless steel. It has high strength and corrosion resistance. The following datasheet gives more details about grade 317 stainless steel.


Grade 317 stainless steel is tougher than 304 stainless steel. It is recommended to use chip breakers. Hardenability of this alloy will be reduced if constant feeds and low speeds are used.


Grade 317 stainless steel can be welded using fusion and resistance methods. Oxyacetylene welding method is not preferred for this alloy. AWS E/ER317 or 317L filler metal can be used to obtain good result.

Hot Working

Grade 317 stainless steel can be hot worked using all common hot working procedures. It is heated at 1149-1260°C (2100-2300°F). It should not be heated below 927°C (1700°F). Post-work annealing can be done to retain the corrosion resistance property.

Cold Working

Stamping, shearing, drawing, and heading can be done successfully. Post-work annealing is performed in order to reduce internal stress.


Grade 317 stainless steel is annealed at 1010-1121°C (1850-2050°F) followed by cooling.


Grade 317 stainless steel does not react to heat treatment. It can be hardened by cold working.


Grade 317 stainless steel is used in the following applications:
Pulping paper
Chemical equipment
