1.4841 | X15CrNiSi25-21

Heat-resistant steel

Austenitic steels such as 1.4841 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. In order to avoid overheating or burn-through with thinner sheets, high welding speeds must be used. Grade 1.4841 is suitable for components that need to be scale resistant up to about 1150 °C.
