- Textile and pharma plants
Welding SS 317L
Good. Use ER317L filler (or a higher-alloy filler for severe service) to keep molybdenum levels in the weld.
Forming and machining
Forms and machines like 316L, with slightly higher strength.
SS 317L sizes we supply
Plates and sheets, with pipes and bars on order.
SS 317L price compared with 304
Above 316L because of its higher molybdenum and nickel, but well below 904L. For today's rate, send us your size and quantity.
Our advice
Specify 317L when 316L pits in chlorides or acids but 904L would be over-specified for the budget.
Values are typical ASTM A240 limits for flat products and are for guidance only. Always refer to the mill test certificate supplied with the material.
