ASTM A517 Qib A
Hom: Siab-Lub zog, Quenched & Tempered Alloy Steel Phaj.
Kev Siv Tseem Ceeb: Fusion-welded boilers thiab cov hlab ntsha siab.
Cov yam ntxwv tseem ceeb: Muab lub zog tensile siab, nrog rau cov qib tshwj xeeb (xws li A, B, E) muab cov khoom sib txawv thiab cov khoom sib txawv.
Alloy: Qib A tshwj xeeb suav nrog cov khoom xws li Chromium (Cr), Molybdenum (Mo), thiab Boron (B) rau kev txhim kho cov khoom.
ASTM A533 Qib A
Hom: Tsawg Alloy Steel Phaj, Quenched & Tempered (Class 1 yog normalized, Class 2 Q&T).
Kev Siv Tseem Ceeb: Hnyav- cov hlab ntsha ua haujlwm siab, tshwj xeeb tshaj yog nyob rau hauv cov ntawv siv nuclear, vim muaj zog dua.
Lub ntsiab feature: Paub tias yog "nuclear qib" rau nws zoo heev notch toughness thiab zoo weldability.
Alloy: Manganese-molybdenum (Mn-Mo) alloy, muaj carbon, manganese, silicon, thiab molybdenum.
