A high heat resistance as well as a particularly high (or low) thermal coefficient of expansion belongs to the further extreme characteristics of Ni-resist. Ni-resist is erosion resistant, non-scaling and not magnetizable. The nickel quotient increases the tensile strength and the elongation of this material.
Ni-resist does not form a passive layer in contact with sea water or alkaline materials. Ni-resist can be machined better than cast steel and is usually more economical to produce. The structure of Ni-resist is austenitic, very strongly enriched with nickel (photo right). The high nickel content is decisive for the unusually high corrosion resistance of the material.
