34CrNiMo6 W-Nr 1.6582 Stainless Steel Flat Bar JIS SNCM447 Steel Hollow Bar

34CrNiMo6 W-Nr 1.6582 Stainless Steel Flat Bar JIS SNCM447 Steel Hollow Bar

Product Information

DIN 1.6582/34CrNiMo6 is a heat treatable low alloy steel containing chromium, molybdenum and nickel as reinforcements. Known for its good strength, toughness, hardenability and ability to develop high strength by maintaining high fatigue strength under heat treatment conditions, but poor weldability, usually the steel should be quenched and tempered before use.
