TusASTM B42 Seamless Tooj Yeeb Nkabyog tsim los ntawmphosphorus - deoxidized, siab nyob rau hauv phosphorus (DHP) Toojtsim raws liUnic tsis yog c12200Cov. Cov alloy muab kev tiv thaiv zoo heev rau hydrogen embrittlement thiab zoo tshaj thermal thiab hluav taws xob conductivity. Lub seamless qauv sawv daws cov phab ntsa thickness, txeej} Kev ua tau zoo rau kev ua haujlwm dawb, thiab muaj zog rau kev siv dej tshuab, HVAC, thiab cov ntawv thov engineering.
Txhua cov yeeb nkab yog tsim tawm hauv kev ua raws liASTM B42Thiab yog raug rau kev sim nruj rau cov tshuaj muaj tshuaj lom neeg, cov khoom siv neeg siv cov neeg siv tshuab, thiab qhov tseeb.
