Description:
317L is an austenitic stainless steel with a 3% molybdenum addition. Alloy 317L exhibits
an austenitic microstructure, free of chromium carbide precipitations at grain boundaries. The grade contains some
residual ferrite (after solution annealing (1100 - 1150°C / 2012 - 2102°F)) and water quenching.
The high molybdenum content gives this steel a higher resistance to corrosion in sulfuric media than standard grades
(316 / 316L).
It is with properties as: high ductility, weldability and improved corrosion resistance.
The main application are refining, chemical industries, pulp and paper industry
