Description and uses:

production of steel strips

Austenitic stainless chrome-nickel steel, with the addition of molybdenum. Multi-use steel with excellent properties for springs, in relation to 12R11 it has got superior mechanical strength, better tempering properties, higher resistance to relaxation (at high temperatures) and improved corrosion resistance (addition of molybdenum).
