Ni Resist4 Tonnes
Austenitic Cast Irons
These are Irons alloyed with high percentages of Nickel and Chromium. Basically they are the iron equivalents of Stainless steel in their properties, but alas not their looks. Two basic types are available based on the type of carbon.
Contact us01484 428203The graphite appears as either flake, as in grey iron or spheroidal as in SG irons. The latter have greater mechanical properties than flake.
Both types, because of the high Nickel, have similar properties of heat resistance and good resistance to salt water and other corrosive materials. Chromium gives the resistance to erosion.
Ni Resist can exhibit low levels of magnetic permeability i.e. they can be non magnetic. Main uses: sea water pump valve parts and high temperature ovens / furnaces.
Selection of General Engineering Grades ASTM A436 & ASTM A439 439 A 439 436 A436 MIL G-858B
| Grade | N/mm² | Material Properties |
|---|---|---|
| F1 | 170 - 240 | Good resistance to corrosion of dilute acids, alkalis and sea water. Good heat resistance. Mining and flanges. |
| F2 | 170 - 240 | Similar to F1but with more corrosion resistance to alkalis |
| S2 | 370 - 490 | Similar to F2 but with superior mechanical properties: marine |
| S5 | 370 - 490 | Excellent resistance to growth and scaling up to 850 deg. C Low thermal expansion and good thermal shock resistance |
