Khoom Description
SA387Gr5CL2 steel phaj tuaj yeem tiv taus qhov corrosion tsim thaum lub sij hawm roj av tawg, nyob rau hauv qhov kub thiab txias, nrog oxidation tsis kam thiab txaus kub lub zog thiab kub tsis kam ntawm hav zoov hlau yog hu ua kub hlau. Qib no ntawm cov hlau phaj yog ib txhiab alloy steel chav kawm, ntawm txog 650 degrees Celsius muaj hav zoov oxidation tsis kam, ntawm 600 degrees Fahrenheit hauv qab no muaj thermal zog zoo, thiab muaj ntuj shock absorb thiab thermal conductivity, dav siv nyob rau hauv chav turbines.
