Stainless steel

1.4828 | X15CrNiSi-20-12

Heat-resistant steel

Austenitic steels such as stainless steel grade 1.4828 have only 30% of the thermal conductivity of unalloyed steels. Their melting point is lower than that of unalloyed steels, so austenitic steels must be welded with lower heat input than unalloyed steels. This grade is suitable for components that need to be scale-resistant up to about 1000 °C. The material 1.4828 can be weakly magnetisable in the quenched state. The magnetisability increases with increasing cold deformation.
