34CrNiMo6 is a quenching and tempering steel with high strength, high toughness and good hardenability. Used for large axles, machine components, tools and high strength fasteners.
The steel can be induction hardened and it is weldable under certain conditions. Through hardenability to appr. 100 mm diameter bar with oil quenching.
356D - Standard steel variant
356Q - IQ (isotropic quality) variant.
6499 - low sulphur variant of 34CrNiMo6 Suitable for fasteners according to ISO 989 Grade 10.9 up to 90 mm bar diameter
6498 - A variant of the old swedish standard SS 2541
6502 - M-steel variant of 34CrNiMo6
SB9205 - A variant of 34CrNiMo6
The basis for the concept is that non-metallic inclusions are modified and controlled with calcium treatment in a way to minimize tool wear and to maximize chip control in machining operations.
Our M-Steel treatment can be applied to any steel grade.
