Detailed Product Description

S31726,317LMN,F48,EN 1.4565,

CLC 17-13-5LN (317LNM) is a Nitrogen alloyed austenitic stainless steel with a high Molybdenum addition (=4%). Alloy CLC 17-13-5LN (317LNM) exhibits austenitic microstructure free of deleterious carbide precipitations in grainboundaries. The grade contains some residual ferrite (=2%) after solution annealing (1100 - 1150°C / 2012 - 2102°F) and water quenching. Its low carbon content avoids the intergranular corrosion, even on welded pieces without an ulterior water quenching. The high Molybdenum content gives this steel a higher resistance to corrosion in chloride containing environments than standard grades (CLC17-12-2L / 316L). Nitrogen additions and a low silicon content have a stabilizing effect on austenitic structure reducing, therefore, precipitation of inter-metallic phases during welding. Nitrogen addition also increases the yield strength compared to CLC 18-15-4L (317L). Its main properties are : high ductility, easy weldability and high corrosion resistance.

The main applications are chemical and petrochemical applications, pollution control equipments and chemical tankers.
