Heat-resistant steel-a hlawkna bulpui ber chu a high-temperature chakna leh oxidation resistance tha takah a awm a ni. High-temperature environment hnuaiah chuan steel pangngai chu a nem emaw, a oxidation emaw a awlsam a, chu chuan structural failure a thlen thin. Heat-resistant steel hian dense oxide film a siam a, chu chuan alloy elements chromium, nickel, leh molybdenum te a dah a, chu chuan high-temperature oxidation leh corrosion te chu a do tha hle a ni. Entirnan, heat-resistant steel chromium content 12% aia tam nei chuan 800℃aia sang environment-ah stability a vawng reng thei a, boiler, heat exchanger leh hmanraw dang dangah pawh hman a ni nasa hle.
Chu bakah, heat-resistant steel-a high-temperature creep performance pawh hi thil langsar dang a ni bawk. Creep tih hian thil pakhat chu long-term high-temperature load hnuaia zawi zawiin a inthlak danglam thin tih a kawk a ni. Alloy composition leh heat treatment process optimize hmang hian tunlai heat-resistant steel hian creep rate chu nasa takin a tihhniam thei a, high-temperature leh high-pressure environments hnuaia hun rei tak rintlak operation a tichiang thei a ni.
