Alloy steels lossis siab lub zog cov hlau yog cov roj carbon hlau tsawg lossis cov hlau nyob rau qis kawg ntawm cov pa roj carbon hauv nruab nrab. Alloy cov hlau muaj cov khoom sib ntxiv ntxiv kom lawv lub zog, hnav tsis kam lossis lub zog tshwj xeeb. Cov kev sib dhos no suav nrog chromium, molybdenum, silicon, manganese, npib tsib xee thiab vanadium. Cov ntsiab lus tseem ceeb tshaj plaws ntawm impurities xws li phosphorus lossis leej faj yog txwv.
Tus Qauv Txheej Txheem rau A234 WP91 npog ob lub fittings uas tau tsim nrog ob leeg ua tsis tau zoo li welded kev tsim kho. Nyob rau hauv lub sij hawm A234 WP91, WP91, WP91, WP91, WP91 yog hu ua ib qho ntawm cov qauv steel hauv cov qauv steel nyob rau qhov twg w txhais tau tias wands rau siab thiab tus lej 91.
Tus nyob hauv Greek
Txhawm rau ua piv txwv, tsab ntawv w hauv lo lus WP sawv rau weldable, thaum tus tsiaj ntawv P sawv rau siab, thiab tus lej 91 yog nws txoj kev ntaus nqi. Kev lag luam xws li roj, roj, kev kho dej, tshuaj, thiab cov nroj tsuag hluav taws xob feem ntau siv hauv lawv cov ntawv thov txhua hnub. Vim yog cov ntsiab lus qis dua hauv cov fittings teev los ntawm ASTM A234, lawv lub hardness yog siab dua. Raws li qhov tshwm sim, A234 WP91 WPDED Fittings zoo li ua tau zoo dua hauv cov ntawv thov ua kom tsis txhob ua hauj lwm tsis kam thiab mob plab tsis kam. Taub qab welded pob qij txha, xws li astm A234, yog cov lus qhia tshwj xeeb uas npog cov pob qij txha sib dhos thiab cov pob qij txha welded tsim cov qeb carbon thiab alloy. Ib qib twg yog WP91 accessory.
