About Alloy 230

Alloy 230 has outstanding oxidation resistance and superior strength up to 1149 °C. Comparable to Alloy 600, Alloy 230 exhibits excellent nitriding and carburising resistance. The alloy is one of the most nitriding-resistant materials available.

Alloy 230 has excellent creep and fatigue resistance combined with long-term stability. In addition the alloy is resistance to grain coarsening when subject to elevated temperatures for prolonged periods.

Alloy 230 is easily fabricated and welded. As a result of its good ductility, Alloy 230 is readily formed by cold working.

FAQs & Resources

Carburising or carburisation refers to a process in which metals i.e. steel, stainless steel etc. are heated in a carbon-bearing atmosphere. Carburisation can be advantageous or disadvantageous depending on the intent of the operation. Under controlled heat treatment process, it is used to harden the surface of a material. On the other hand, it can cause premature failure and cracks when components made of materials susceptible to carburisation are used in the high temperature carbon-containing process.
