ASTM A106 B thiab ASTM A53 B yog ob hom seamless steel kav, txhua tus muaj cov yam ntxwv sib txawv thiab siv.
ASTM A106 B Cov Lus Qhia:
Kuj tseem hu ua seamless steel yeeb nkab rau kev ua haujlwm kub, nws yog tsuas yog siv nyob rau hauv high-temperature thiab high-pressure boilers thiab superheater systems. Nws cov tshuaj muaj pes tsawg leeg suav nrog C, Mn, P, S, Si, thiab lwm yam, thiab ua tau raws li cov khoom siv tshwj xeeb, xws li lub zog tensile thiab yield zog. Vim tias qhov tsim nyog ntawm cov ntsiab lus alloying, A106 B muaj cov cua sov zoo dua thiab cov khoom siv kho tshuab.
ASTM A53 B Cov Lus Qhia:
Haum rau cov kav dej siab, cov kav dej thiab cov kav dej dav dav uas muaj qhov kub thiab txias hauv qab 350 degree.
Nws cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv tshuab sib txawv ntawm A106 B, thiab feem ntau nws yog siv hauv qhov chaw ua haujlwm tsawg dua. Si cov ntsiab lus ntawm A53 B yog 0, thaum Si cov ntsiab lus ntawm A106 B muaj qhov tsawg kawg nkaus tus nqi yuav tsum tau, uas ua rau A106 B zoo dua A53 B nyob rau hauv tshav kub kub.
ASTM A106 B thiab ASTM A53 B yog ob qho tib si qauv rau seamless steel kav, tab sis lawv cov tshuaj muaj pes tsawg leeg, txhua yam khoom thiab daim ntawv thov scenarios txawv. A106 B yog qhov tsim nyog rau qhov kub thiab txias qhov chaw ua haujlwm siab, thaum A53 B yog qhov tsim nyog rau qhov kub thiab txias thiab qhov xav tau tsawg dua. Thaum xaiv, tus qauv tsim nyog seamless steel yeeb nkab yuav tsum tau xaiv raws li qhov tshwj xeeb siv ib puag ncig thiab kev xav tau.
