cleaning gray ductile iron casting iron machining ni resist

Ni Resist is easier to machine than stainless steel. Machining allowances are lower on Ni Resist castings when compared to stainless steel. Castability. As with Grey Iron and SG Iron, Ni Resist castings offer all of the design benefits associated with Iron Castings. Complex shapes can be accommodated, excellent surface finish will be achieved and complex designs can be undertaken. Ni-Resist Specification BS …

Ni-resist: ductile cast iron for corrosive application; Vermiculair cast iron. The carbon occurs in the form of "exploded" graphite. It is in fact 'failed' ductile iron. It combines good thermal conductivity properties of lamellar cast iron with higher tensile strengths. The disadvantage is that the production process has to be followed very precisely in order to obtain the right quality. White cast iron
