Haynes 230 Plate, Sheet, & Bar
(AMS 5878, ASTM-B-435, AMS 5891, UNS N06230)

Haynes 230 alloy is used for a wide variety of applications in the aerospace and power generation industries because of its excellent high-temperature strength, thermal stability, environmental resistance and excellent forming and welding characteristics. In fact, HS 230 is readily welded by Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW), Shielded Metal Arc Welding (SWAW), and other resistance welding techniques.

Haynes 230 (UNS NO6230) is a nickel-chromium-tungsten-molybdenum alloy that combines excellent high-temperature strength, long-term thermal stability, and resistance to oxidizing environments up to 2100 °F for prolonged exposures in harsh environments. These characteristics allow Haynes 230 alloy to excel in creep and fatigue resistance at high temperatures. Haynes 230 from Altemp is specified to AMS 5878 & ASTM B-435, 572
