TusA335 P9 Kav, ua los ntawm ferritic alloy - hlau, yog txhais tau rau cov ntawv thov kub siab. tusSA335 P9 Khoom SivChemically muaj cov hlau xws li Molybdenum thiab chromium ntxiv rau cov alloy.
Los ntawm kev sib ntxiv ntawm cov hlau xws li Molybdenum thiab chromium, muaj kev nce ntxiv hauv lub zog tensile ntawm cov alloy. Cov txiaj ntsig lub zog ntawmtusA335 P9 Welded Yeeb Nkabyog 205 MPa, thaum nws lub zog tensile yog 415 MPa. Feem pua ntawm cov yeeb nkab ntawm cov yeeb nkab yog li 30%.
Ob qho tib si cov ntsiab lus no paub los txhim kho cov yeeb nkab tiv thaiv kev coj, nws qhov kev cuam tshuam, nyuaj, raws li nws cov kev txwv ywj. Lawv kuj ua rau muaj kev nce ntxiv rau hauv nws cov khoom siv xws li- kev tiv thaiv, qhov nce siab tshaj plaws ntawm kev ua kom sov siab thiab muaj kev tiv thaiv zoo heev.
Cov ntsiab lus chromium nyob rau hauva335 p9Yeeb nkab ua rau nws muaj peev xwm tiv taus corrosion. Yog li ntawd, tusa335 p9, tau ua kom zoo heev rau oxidation thaum lub siab kub. Dhau li ntawm chromium, Astma335 p9 Alloy Steel Kav hlau uas yog sab nraud roj nrog cov xim roj dub los yog anti {{{} corrosion roj qhia zoo rau corrosion. Nws kuj tseem tuaj yeem yog galvanized nrog zinc. Galvanization nrog zinc nce nws txoj kev tiv taus rau atmospheric corrosion.
