International identifiers
AISI 630, AFNOR Z7CNU15-05, ASTM 17-4PH, UNS S17400, AFNOR Z7CNU17-04, JIS SUS630, GB 05Cr17Ni4Cu4Nb

1.4542 is a stainless steel that exhibits good corrosion resistance, high yield strength and high wear resistance. It is analytically similar to 1.4548 and 17-4PH.

When stored at conditions H1150 and H1025, 1.4542 can also be worked at low temperatures! 1.4542 features excellent notch impact strength at minus temperatures.

1.4542 steel is suitable for use in maritime environments due to its combination of good mechanical properties and corrosion resistance.

1.4542 provides an excellent solution if stronger corrosion resistance and mechanical properties are required than those provided by martensitic steels.

This stainless steel is susceptible to crevice corrosion in stagnant seawater.

1.4542 is popularly known as AISI 630​​​​​.

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.
