Unlike alloy 230 (Ni‑based), alloy 188 retains better low‑cycle fatigue resistance at intermediate temperatures but has slightly lower oxidation limits above 1000 °C.
In the world of advanced materials, the spotlight often falls on the flashy newcomers—titanium superalloys, graphene, or carbon composites. But quietly holding the backbone of modern industry together are the "Stell" workhorses. Among them, (a ferritic stainless steel variant developed for high-temperature applications) deserves its moment in the sun. haynes 4.89
