1.4122 (X39CrMo17-1) directly from stock & cut to your required dimensions!

International identifiers
AFNOR Z38CD16-01, 3H17M

1.4122 - same or slightly better corrosion resistance than 1.4016. Excellent mechanical properties achievable with targeted heat treatment.

1.4122 better corrosion resistance than the 13% chromium steels, such as 1.4006, due to 17% chromium content. Resistant in media with low aggressiveness and low chlorine-ion concentration. Pitting susceptibility lower due to the molybdenum additive. Optimal corrosion resistance with polished surface.

Applications in mechanical engineering, apparatus engineering, plastics processing, fittings and pump manufacture.

Advantages of saw cut

The processing with the saw is a mechanical processing of the material, which results in a significantly lower unintended deformation and increased hardness for the existing structure, such as the thermal cutting. Thus, the machined workpiece has a homogeneous structure even at the edge, which does not change in the continuation of the material.

This circumstance allows immediate finishing of the workpiece with milling or drilling . So it is not necessary to anneal the material or make a similar operation beforehand.
