DIN 34crnimo6 steel round bar 1.6582 steel bar
Features
34CrNiMo6 Steel is an important alloy engineering steel grade as per BS EN 10083-3:2006. 34CrNiMo6 steel has high strength, high toughness and good harden-ability.
34CrNiMo6 is applied in industries such as aviation, automotive, automotive, and national defense. 34CrNiMo6 can undergo heat treatment such as normalizing, tempering, and quenching. It is used to manufacture chains, screws, gears, arms, rollers, and various other mechanical parts.
