Stainless steels, with a substantial content of chromium and other alloying additions for aerospace applications, offer corrosion resistance in addition to the desired mechanical properties. Various grades available include martensitic, austenitic and precipitation hardening (PH). Some grades may be hardened and tempered. In some instances material is supplied VAR (vacuum arc re-melted) or ESR (electro-slag refined) to promote greater structural integrity.


Aerospace stainless steels are defined within the British Standard Aerospace series using a designation system within which all grades begin with the letter ‘S’ . Various other designation systems and standards exist. For example, we supply a number of American Aerospace grades which are released to AMS specifications. Care should be taken with the specification selection for purchase as similar alloys in different National Standards are often not directly equivalent.
