Industeel CLC 18.12.4 LN 3%Mo Austenitic Stainless Steel with Nitrogen Addition

 

Subcategory: Stainless Steel; T S30000 Series Stainless Steel; Metal; Austenitic

Key Words: EURONORM 1.4434 X2CrNiMoN18.12.4, AFNOR Z3 CND 19-14 Az, DIN W 1.4434, ASTM A240 TP 317LN, UNS S31753

Material Notes:
Description: CLC 18-12-4LN (317LN) is a Nitrogen alloyed austenitic stainless steel with a 3% Mo minimum addition (>4%). Alloys CLC 18-12-4LN (317LN) exhibit 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 chlorides environments than standard grades (CLC17-12-2L / 316L). Nitrogen additions improves structure stability, increases the yield strength and improves pitting and crevice corrosion resistance when compared to CLC 18-15-4L (317L). Its main properties are : high ductility and improved corrosion resistance. The main applications are chemical and petrochemical applications, pollution control equipments and chemical tankers.

Iron content calculated as remainder.
