Dab tsi yogASTM A312 unnongless Duplex Boiler Kav?
ASTM A312 undu s31254 Stainless hlau seamless cold- ua tiav cov tubing yog suav tias yog ib qib Austenic tiav. Nws yog peb zaug muaj zog dua 300 series stainless hlau. SMO254 tubing zoo tiv thaiv pitting, crevice corrosion, thiab chloride kev ntxhov siab corrosion. Nws tseem muaj lub npe hu ua Moly 6 vim ntxiv rau cov kab ntxiv ntawm Molybdenum {{Soon} Sno Tubring cov chaw pom zoo kom lawv muaj lub zog siab txawm tias tsis muaj peev xwm tsis ruaj khov. Lawv tau siv hauv boiler thiab cua sov ua pa, muab lub zog loj, weldability zoo, thiab kev tawm tsam chloride kev ntxhov siab corrosion.
