1.4835 – heat-resistant steel
Flexible process 1.4835 for prototyping and production parts using 3D printing
1.4835 is an austenitic stainless steel for use as a high temperature material. It is 1.4828 stainless steel with increased nitrogen content and added rare earth metals. The material has good mechanical properties and very good scaling resistance in dry air if used up to 1100 °C. The temperature’s range from 600 to 900 °C should be avoided, though, because intergranular attack can occur, which has a negative impact on the notch impact strength.
Due to the relatively high N and C content, durability is poor in reducing or oxidising atmospheres. This applies in particular to gases containing sulphur.
In the solution annealed state, the material is not magnetic. Low magnetism, however, can be caused by the formation of deformation martensite or by welding. Typical applications for 1.4835 are the manufacturing of industrial furnaces, heat treatment plants in the metalworking industry, accessories for hardening shops, the cement industry, apparatus engineering and chains.
