Alloy Steel ASTM A335 P12 Yeeb Nkab
Dab tsi yog qhov txawv ntawmASTM A335 P11thiab P12?
Qhov sib txawv ntawm P11 thiab P12 yeeb nkab yog cov tshuaj muaj pes tsawg leeg. P11 muaj txog li 1.25% chromium thiab mus txog 45% molybdenum, thaum qib P12 muaj txog li 1% molybdenum nyob rau hauv nws muaj pes tsawg leeg. Ua rau sib txawv corrosion kuj thiab hardness ntawm ASTM A335 P12 seamless yeeb nkab.
A335 P12 steel hlau yeeb nkab yog qhov kub-kub chromium-molybdenum alloy steel rau boilers. Qib ntawm cov hlau hauv GB5310-2008 "Seamless Steel Pipe rau High-Pressure Boilers" yog 15CrMoG. Qhov sib xyaw ua ke yog 1Cr-0.5Mo. Nws tsis tsuas yog muaj qhov zoo Nws muaj cov oxidation zoo heev thiab kub-kub chav corrosion kuj, nrog rau zoo cuam tshuam toughness thiab siab thermal zog. Nws tau siv dav hauv cov kav dej loj thiab cov kab sib txuas ntawm qhov kub thiab txias ntawm lub peev xwm loj thermal fais fab hauv ntau lub teb chaws thoob ntiaj teb.
A335P12 alloy steel kav tuaj yeem muab faib ua peb hom: carburized, quenched thiab tempered thiab nitrided steels. Lawv muaj cov khoom siv zoo dua qub dua li cov kav dej carbon steel. P12 alloy yeeb nkab yog tsuas yog siv rau cov cua kub ntawm cov kav dej ntawm qhov qis thiab nruab nrab siab boilers; rau cua sov nto kav dej ntawm high-pressure boilers, economizers, superheaters, reheaters, petrochemical kev lag luam kav, thiab lwm yam.
