PART II. THE METALLURGY OF: “ALLOY SELECTION FOR ELEVATED TEMPERATURE APPLICATION”

Malabou cast special alloys that allow for castings to be used at elevated temperature’s, in some cases in excess of 1000°C.

These heat resistant casting alloys consist of predominantly of combinations of nickel, chromium and iron together with small percentages of other elements.

Castings made of these high temperature alloys exhibit good mechanical strength and toughness at elevated temperature as well as oxidation and corrosion-resistance in environments as temperatures where they are to be used.

Castings to be used at elevated temperature’s, in some cases well in excess of 1000°C.

High Temperature Casting Classifications

The common designations for cast alloys are descriptive of their chemistry and purpose. This designation system was established by the Alloy Casting Institute (ACI) and has been adopted by ASTM.

The Alloy Casting Institute designations use “H” to indicate alloys generally used in applications where temperature is more than 537°C (1000°F). The second Letter represents the nominal nickel content, increasing from A to X.

Heat-resistant casting alloys are classified per metallurgical structure and composition it to three groups:

Chromium-Iron alloys: e.g. HA, HC, HD

Chromium-Nickle-Iron alloys: e.g. HE, HF, HH, HI, HK,HL

Nickel-Chromium-Iron alloys: e.g. HN, HT, HU, HW, HX

 Furnace Rabble Arms,

 Grizzly Bars,

 Hot Pan Conveyors,
