Cov khoom muaj pes tsawg leeg: ASTM A179 seamless steel yeeb nkab feem ntau yog ua los ntawm carbon (C) steel, nws cov khoom tseem ceeb muaj xws li carbon, manganese (Mn), phosphorus (P), sulfur (S) thiab lwm yam. Cov ntsiab lus no ua rau nws haum rau cov ntawv thov kub qis nrog cov khoom ua haujlwm txias txias.
Cov ntawv thov kub qis: ASTM A179 seamless steel raj yog tsim rau cov ntawv thov kub tsawg, feem ntau ua haujlwm ntawm qhov kub ntawm -29 degree (-20 degree F) thiab +400 degree (750 degree F). Qhov no ua rau nws zoo tagnrho rau cov khoom siv kub qis xws li cov tshuab cua txias, cov khoom siv hluav taws xob thiab cov condensers.
Cold-drawn manufacturing process: Lub raj no feem ntau yog tsim los ntawm cov txheej txheem tsim khoom txias, uas txhais tau hais tias lub raj yog ncab ntawm chav tsev kub kom tau txais nws qhov kawg loj thiab phab ntsa tuab. Cov txheej txheem no yuav pab tau los txhim kho qhov smoothness ntawm cov yeeb nkab thiab sab hauv cov txheej txheem.
Corrosion resistance: ASTM A179 seamless steel kav feem ntau ua haujlwm ntawm qhov kub thiab txias, yog li lawv feem ntau tsis cuam tshuam los ntawm oxidation lossis corrosion ntawm chav tsev kub. Txawm li cas los xij, rau qhov tshwj xeeb corrosive ib puag ncig, kev tiv thaiv corrosion ntxiv yuav xav tau.
Cov khoom siv kho tshuab: ASTM A179 seamless steel kav feem ntau muaj cov khoom siv nruab nrab, nrog rau lub zog tensile, yield zog thiab elongation. Cov kev ntsuas no yog qhov tseem ceeb hauv qhov kub thiab txias ib puag ncig kom ntseeg tau cov kav dej.
Cov cim thiab cov cim: ASTM A179 seamless steel kav feem ntau yog luam tawm nrog cov chaw tsim khoom lub logo, yeeb nkab specification, qib, qhov loj me thiab cov xov tooj cua sov los pab txheeb xyuas thiab taug qab cov yam ntxwv ntawm cov yeeb nkab.
