Nws tau muab cov normalized thiab tempered, ua tau raws li qhov yuav tsum tau nruj me ntsis mechanical, tshwj xeeb tshaj yog tawm lub zog (min 45 ksi) thiab tensile zog (75-100 ksi).
Cov yam ntxwv tseem ceeb
Lub zog:Lub zog siab dua li Chav Kawm 1, nrog qhov tsawg kawg nkaus lub zog ntawm 45 ksi (310 MPa) thiab tensile lub zog ntawm 75-100 ksi (515-690 MPa).
Kuj:Zoo heev oxidation, corrosion (xws li roj qaub), thiab creep kuj.
Qhov xwm txheej:Muab khoom normalized thiab tempered.
Khoom siv:Chromium-Molybdenum (Cr-Mo) Alloy Steel.
Daim ntawv thov:Kev pabcuam kub siab hauv cov hlab ntsha siab, boilers, kub exchangers, thiab lwm yam.
Alloying Elements:
~ 2.25% Chromium, ~ 1% Molybdenum (Qib 22)
.
Siv dav
Petrochemical reactors, hydrogenation units, muaj boilers.
Roj & roj pipelines, refineries, offshore / onshore chaw.
Kev tsim hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv tshuaj lom neeg.
Qhov Tseem Ceeb Qhov txawv: Chav 1 vs. Chav Kawm 2
Chav kawm 2muaj qhov yuav tsum tau muaj zog ntau dua (siab dua qhov qis tshaj tawm / lub zog tensile) thiab dhau kev nruj dua - ntsuas qhov kub thiab txias, ua rau nws tsim nyog rau kev pabcuam hnyav dua li Chav Kawm 1.
