SA 387 GR.22 CL.1PLATES yog molybdenum-chromium alloy steel phaj ntxiv rau nws suav nrog manganese thiab silicon cov ntsiab lus. Cov paib pom nws daim ntawv thov nyob rau hauv weldable carbon steel kev nyuaj siab hlab ntsha ntawm soaring kub. Lub xub ntiag ntawm chromium cov ntsiab lus muaj superior corrosion kuj thaum molybdenum cov ntsiab lus muab lub zog tensile zoo heev ntawm qhov kub siab. Cov qib ntawm daim hlau no muaj qhov ua tau zoo dua thiab ua kom muaj kev ntxhov siab zoo heev. Vim cov txheej txheem annealing thiab normalizing cov phiaj no tau txais pob zeb nyuaj. Whereas lub annealing kom toughens saum npoo los ntawm kev txo cov kev ntxhov siab sab hauv. Cov phaj yog superior malleable daim hlau uas muaj zoo formability thiab xeb pov thawj tiav.

1.Dab tsi yog SA387 qib 22 khoom?
SA387 Qib 22 yog chromium-molybdenum (Chrome-Moly) alloy steel phaj, teev los ntawm ASME / ASTM cov qauv, tsim los rau siab- qhov kub thiab txias kev pab cuam hauv boilers thiab siab hlab ntsha, muab lub zog zoo heev, durability, thiab tsis kam mus rau oxidation thiab corrosion, tshwj xeeb tshaj yog nyob rau hauv qaub ib puag ncig ntawm cov roj tseem ceeb, chromium 2% ua tsaug rau nws cov ntsiab lus tseem ceeb ntawm 2%. (kwv yees li 1%) cov ntsiab lus.
2.Yog SA 387 Qib 22 Chav Kawm 1 steel phaj zoo zoo?
Yog lawm, SA 387 Qib 22 Chav Kawm 1 steel phaj yog suav tias yog cov khoom zoo - cov khoom zoo, tshwj xeeb tsim rau cov hlab ntsha siab hauv siab - qhov kub thiab txias, muab cov cua sov ua haujlwm zoo, lub zog, thiab corrosion kuj vim nws cov chromium- molybdenum alloy muaj pes tsawg leeg, ua rau nws zoo tagnrho rau cov roj, roj, thiab petrochemical fluid tam sim no.
