WebJan 15, 2024 · Stainless steel is an example of a combination of interstitial and substitutional alloys, because the carbon atoms fit into the interstices, but some of the iron atoms are replaced with nickel and chromium atoms. 6.7C: Intermetallic Compounds WebWhen 18% chromium and 8% nickel are added, the crystal structure of austenite remains stable over all temperatures. The nickel-based alloys with 35-70% nickel and 20-30% chromium, while not strictly steels (a steel must have at least 50% iron), do have the face-centered-cubic lattice arrangement and are also called austenitic materials.

WebFerritic stainless steels have a “body-centred-cubic” (bcc) crystal structure, which is the same as that of pure iron at room temperature. The main alloying element is chromium, with contents typically between 11 and 17%, although a higher chromium content of about 29% is found in one specialised grade.

Web15.4.2 Martensitic stainless steels (MSS) MSS are Fe-Cr-C- (Ni-Mo) alloys that have a body-centered tetragonal (bct) crystal structure (martensitic) in the hardened condition. They are ferromagnetic, hardenable by heat treatments, and generally resistant to corrosion only in relatively mild environments ( ASM International, 2001b ).
