Goodwin Steel Castings
Precipitation hardened nickel alloys are suitable for use in high temperature and high pressure environments such as A-USC (+700°C) power generation because of their excellent creep resistance and corrosion properties.
Goodwin are the world leaders in supplying super nickel alloy castings for corrosion and high temperature applications.
Super austenitic stainless steel such as CK3MCuN (254 SMO)
Duplex and super duplex stainless steel castings supplied using the AOD refining process for excellent composition control.
Austenitic 304 and 316 stainless steel castings supplied for architectural applications (ASTM CF3/M, CF8/M, CF8C) .
Martensitic cast steels for Supercritical and Ultra-Supercritical applications up to 620°C.
Alloy Steel High tensile alloy steel castings for structural applications. NiCrMo steels and 13Cr 4Ni CA6NM steels.
Supplied as machined castings and assembled MSV and RSV-ICV valves for the power generation industry.
Carbon steel castings for low temperature applications which are also readily weldable.
The common defining characteristic of this group of materials is the shape of the graphite. In ductile irons, graphite is in the form of nodules rather than flakes as in grey iron
