1.4034 - x46cr13 stainless steel from stock

What is 1.4034 (X46Cr13)

1.4034 can be hardened. Due to its higher carbon content it is higher hardened than the 1.4031. This material is resistant to moderately aggressive media. Optimal corrosion resistance in hardened condition with polished or ground surface. The chemical composition and properties are similar to material 1.2083.

1.4034 is also known under the classification AISI 420.

Properties of the material 1.4034 (X46Cr13)

Properties

Weldability	bad
Machinability	medium 5 (1 = poor - 10 = good)
Polishing	yes
Malleability	well
Corrosion class	1 (0 = weak - 5 = good)
Magnetisability	available

Forging: by Forging a slow heating to over 800°C takes place. Thereafter a rapid heating between 1050°C to 1150°C. The forging process takes place in the temperature range between 1100°C and 800°C. Slow cooling is made in the oven or in dry ashes.

Welding: the 1.4034 is less suitable for welding. If welding needs to be done, appropriate precautions must be taken.

Corrosion resistance: the 1.4034 is not resistant to intergranular corrosion. In aggressive, non-chloride media, however, a corrosion resistance is given. The best corrosion resistance is available when tempered and with a polished surface.

Sawn blank

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.
