1.4878 (X8CrNiTi18-10)

1.4878 (X8CrNiTi18-10) directly from stock & cut to your required dimensions!

International term:

AISI 321H

Application field:

1.4878 is comparable to material 1.4541.
Exhibits good corrosion resistance in natural environmental media (water rural and industrial atmospheres).
The prerequisite is that chlorine and salt concentrations and concentration of nitric or organic acids are low.
Automotive industry, construction industry, chemical industry, food industry, aerospace, mechanical engineering.

In apparatus commonly used for parts with high mechanical stresses. For parts in furnace: annealing furnaces, muffle furnaces, hardening boxes

Scaling resistance of components up to 850 ° C. To oxidizing and reducing sulfurous gases the resistance is low!

Characteristics:

Weldability: very well

Machinability: 4 (1 = low - 10 = good)

Polishability: worse

Corrosion Class: 3 (0 = low - 5 = good)

Benefit of sawn cuts:

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.
