Astm A335 P11 Cov kav dej

ASTM A335 P11 yog seamless ferritic alloy steel raj tsim rau siab -kev siv kub. Nws yog feem ntau hu ua P11 yeeb nkab thiab tsim nyog rau kev khoov, flanging, thiab kev ua haujlwm zoo sib xws. Lub raj yog tsim los ntawm kev sib xyaw ntawm chromium thiab molybdenum, uas txhim kho nws cov kev tiv thaiv corrosion thiab siab - qhov kub thiab txias. Nws yog dav siv nyob rau hauv siab - qhov kub thiab txias ib puag ncig xws li fais fab nroj tsuag, petrochemical kev lag luam, thiab nyob rau hauv kev tsim khoom ntawm cov khoom rau spacecraft thiab dav hlau engine.

Khoom Description

ASTM A335 P11 Yeeb Nkab

Qhov zoo ntawm ASTM A335 P11 Yeeb Nkab hauv Daim Ntawv Thov

ASTM A335 P11 yeeb nkab muaj cov cua sov ua kom muaj zog thiab tuaj yeem tiv taus qhov kub thiab txias (txog 1112℃F) yam tsis poob lub zog, ua rau nws haum rau cov kav dej. Tsis tas li ntawd, chromium thiab molybdenum tuaj yeem txhim kho oxidation tsis kam thiab tiv thaiv -scaling peev xwm nyob rau hauv boiler tej yam kev mob.
ASTM A335 P11 yeeb nkab muaj zog corrosion kuj thiab tuaj yeem tiv thaiv sulfide thiab chloride kev nyuaj siab corrosion tawg hauv cov txheej txheem refining hauv roj thiab roj refining.
ASTM A335 P11 yeeb nkab muaj lub zog siab ua haujlwm thiab ua tau zoo nyob rau hauv ob qho tib si zoo li qub thiab cov kev kub ntxhov, ua rau nws tsim nyog rau kev lag luam siab cov hlab ntsha thiab cov ntawv siv header.
