Esterer Gießerei - High-alloy steel castings

Steel castings with at least one alloy element with a share of more than five mass per cent are defined as „high-alloy steel“.

The most important alloy elements among others are manganese, chromium, nickel, molybdenum, tungsten, vanadium, titan, cobalt and lead.

Parts made of high-alloy steel castings are used when special characteristics as wear, acid, scaling or corrosion resistance are required, Accordingly castings from high-alloy steels are used in rail, automotive and engine construction, at the production of tools, rollers and die iron.

A high-alloy steel casting is according to DIN EN 10020 a part of the general quality class of quality steels (QS) and stainless steels (SS). It is characterised by an X, followed by the carbon ratio times 100 and the element symbols of the alloy elements in the order of descending mass ratio including the information about mass per cent.
