Ni-Resist
austentic cast iron
We produce Ni-Resist in the following grades:
- EN-GJSA-XNiCr20-2 (5.3500)
- EN-GJSA-XNiCrNb20-2 (5.3502)
- EN-GJSA-XNiSiCr35-5-2 (5.3505)
Ni-Resist is used for many products
- Ship propulsion systems
- Pump inserts
- Pump housing
- Pump wheels
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.
