SA285GrC yog qhov qis rau nruab nrab lub zog carbon steel phaj rau cov hlab ntsha siab. Nws yog steel phaj rau boilers thiab yog tsuas yog siv nyob rau hauv zus tau tej cov boilers nyob ruaj ruaj, hull boilers thiab lwm yam tseem ceeb boiler fittings.
Qhov sib txawv tseem ceeb ntawm peb hom carbon steel, SA285A, SA285B thiab SA285C, nyob rau hauv lawv cov txiaj ntsig thiab tensile zog. 165 Mpa thiab 24 Ksi yog qhov tsawg kawg nkaus yield zog rau SA285A siab nkoj steel daim hlau, 185 Mpa thiab 27 Ksi rau SA285B siab nkoj steel daim hlau thiab SA285C siab nkoj steel daim hlau muaj lub siab tshaj plaws yield zog thiab yuav tsum tau siv rau zus tau tej cov boilers taag thiab lwm yam tseem ceeb boiler fittings. Lub zog tawm los ntawm SA285 B qib siab lub nkoj steel phaj yog 185 Mpa thiab 27 Ksi, thaum lub zog tawm los ntawm SA285 C qib siab lub nkoj steel phaj yog siab tshaj, uas yuav tsum siab tshaj 205 Mpa thiab 30 Ksi.
