Introduction This is a complex subject in part due to the time dependant mechanical behaviour of metals under load at elevated temperature. At room temperature, we understand that a part is failing once it is past it’s yield point – plastic deformation is occurring. The part is completely destroyed once…
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…
Of course many of you will know the answer, some of you won’t & some of you will be surprised by the answer. Malabou specialises in making castings in stainless, alloy, mild, and tool steels and we are often asked this question. Background Metallurgy. At room temperature, Mild Steel is…
