1.Dab tsi yog cov khoom siv SA 387 Gr 5 Cl 2?
SA 387 Gr 5 Cl 2 yog Chromium-Molybdenum (Cr-Mo) alloy steel phaj, teev los ntawm ASME, tsim los rau siab - qhov kub thiab txias kev pab cuam hauv welded boilers thiab siab hlab ntsha, featuring tseem ceeb Chromium (nyob ib ncig ntawm 5%) thiab Molybdenum (nyob ib ncig ntawm 0.5% corrosion kuj ntawm 0.5%). qhia tias yuav tsum muaj zog ntau dua li Chav Kawm 1.
2.Yog SA 387 Gr 5 Cl 2 carbon steel?
Tsis yog, SA 387 Qib 5 Chav Kawm 2 tsis yog carbon hlau; Nws yog chrome-molybdenum (Cr-Mo) alloy steel, tshwj xeeb yog tsim los rau siab -kub, weldable siab hlab ntsha thiab boilers, featuring tseem ceeb chromium (kwv yees 4-6%) thiab molybdenum (ib ncig 0.45-0.65%) rau oxidation zog, max., thiab 1.5% cov ntsiab lus oxidation.
