Zoo heev low -kub cuam tshuam toughness (core kom zoo dua)
Lub ntsiab kom zoo dua ntawm ASTM A333 yog nyob rau hauv nws zoo heev uas tsis muaj - kub tej yam toughness. Qhov kev qhia tshwj xeeb no tso cai rau Charpy V- qhov ntsuas qhov cuam tshuam ntawm cov khoom ntawm qhov ntsuas kub tsis tshua muaj, ua kom muaj kev tiv thaiv txaus rau cov pob txha tawg nyob rau hauv qis - qhov kev pabcuam kub. Qib 6 muaj qhov cuam tshuam nruab nrab ntawm lub zog loj dua lossis sib npaug ntawm 18J thiab qhov tsawg kawg nkaus tus nqi ntawm Greater dua lossis sib npaug ntawm 13J ntawm -46 degree, txo qis kev pheej hmoo ntawm kev tawg ntawm cov ntaub ntawv ntawm qhov kub thiab txias thiab ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov kav xa dej thaum muaj kev kub ntxhov.
Kev ua haujlwm vuam zoo
Qhov qis carbon sib npaug tsim ntawm ASTM A333 ua kom zoo weldability nrog cov txheej txheem vuam uas paub tab, ua rau nws haum rau loj - nplai ntawm - qhov chaw teeb tsa. Thaum welding qis-kub steel, yuav tsum tau tswj xyuas nruj ntawm cov cua sov tawm tswv yim los tiv thaiv kom tsis txhob muaj qhov hnyav ntawm cov cua sov- thaj tsam cuam tshuam. Preheating feem ntau tsis tsim nyog ua ntej welding (tshwj tsis yog rau cov kav dej tuab -cov kav dej lossis hauv qhov chaw qis - qhov kub thiab txias), thiab tom qab-weld kev kho cua sov ntawm 600-650℃tuaj yeem xaiv tau tom qab vuam kom txo qis kev ntxhov siab.
Zoo machinability
Nws tuaj yeem dhau los ua ntau yam txheej txheem xws li kub dabtsi yog khoov, txias khoov, thiab forging, ua rau nws tsim nyog rau kev tsim cov yeeb nkab fittings xws li lub luj tshib, tees, thiab reducers. Nws tseem tuaj yeem ua machined siv cov pa machining txoj kev. Nws yuav tsum raug sau tseg tias Qib 3 (3.5% Ni) thiab 8 (9% Ni), vim lawv cov ntsiab lus nickel ntau dua, muaj qhov ua haujlwm siab dua me ntsis piv rau Qib 6.
Cov thev naus laus zis paub tab thiab kev ntseeg siab ntev ntev -
Nws qhia txog kev ruaj ntseg zoo nyob rau lub sijhawm ntev -kev pabcuam nyob rau hauv lawv qhov ntsuas qhov ntsuas kub (Qib 6 Tsawg dua lossis sib npaug rau -46℃/ Qib 3 Tsawg dua lossis sib npaug rau -101℃/ Qib 8 Tsawg dua lossis sib npaug rau -196℃). Xa nyob rau hauv normalized los yog normalized ntxiv rau tempered mob, nws ua tiav ib tug uniform thiab zoo microstructure, ua kom lub koom haum stability thiab kev cia siab rau nyob rau hauv lub low-temperature kev pab cuam.

Kev kho cua sov
normalizing
Kub rau 845-925 degree, tuav lub sijhawm txaus, ces cua txias. Qhov no ua rau muaj qhov sib xws thiab zoo -grained microstructure, txhim kho qhov kub thiab txias toughness. Qhov normalizing kub rau Qib 8 feem ntau yog 845-900 degree, me ntsis siab dua lwm qib.
Normalizing + Tempering (pom zoo rau qib 8)
Tom qab normalizing, kub rau 565-650℃rau tempering, ces cua txias. Qhov no tshem tawm normalizing kev nyuaj siab thiab ntxiv optimizes low-temperature toughness.
Tag nrho Annealing (Yeem)
Thaum tshav kub kub mus rau 815-870 degree, tuav ntawm qhov kub thiab txias, tom qab ntawd lub qhov cub txias kom txog li 650 degree, tom qab ntawd cua txias rau chav sov. Siv los tshem tawm cov kev ntxhov siab ua haujlwm txias lossis txhim kho kev ua haujlwm txias.
Tshaj tawm -Kev kho cua sov (PWHT, xaiv raws li phab ntsa tuab thiab kev ua haujlwm)
Tshav kub rau 600-650 degree, tuav ntawm qhov kub thiab txias, tom qab ntawd maj mam txias kom tshem tawm qhov seem welding stresses.
