ASTM A517 Qib B yog dab tsi?
A517 Qib B yog ib qho classic quenched-thiab-tempered siab- lub zog siab lub nkoj steel tsim los ntawm ASTM rau hnyav- lub luag haujlwm siab- cov khoom siv bearing. Kev tshuaj xyuas thiab kev lees txais cov hlau phaj yuav tsum ua raws li ASTM A20 tus qauv specifications. Txwv tsis pub los ntawm nws thawj qhov chaw tsim khoom, cov khoom no tsuas yog muab los ua nyias daim hlau nrog qhov siab tshaj plaws ntawm 31.75 hli. Txais siv Cr-Mo-V-Ti-B microalloyed tsim, nws ua tiav ultra-lub zog siab tom qab quenching thiab tempering yam tsis muaj ntau ntxiv ntawm nickel{16}}raws li alloys.
EN 10028-6 P690Q yog dab tsi?
P690Q yog lub hauv paus qib ntawm quenched - thiab - tempered siab hlab ntsha steel nrog lub zog tawm ntawm 690 MPa raws li EN 10028 -6 specification. Lub ntsiab lus "Q" sawv cev rau Quenched & Tempered, nrog rau qhov ntsuas kub ntawm -20℃rau Charpy cuam tshuam kev ntsuas. Tsim los nrog ntau-cov ntsiab lus sib xyaw ua ke ntawm Mn-Cr-Mo-Ni, qib steel no rhuav tshem cov thickness txwv ntawm ASTM A517 Qib B thiab ua kom ruaj khov ntawm cov hlau phaj xws li 6 hli mus rau 300 hli thickness.
EN 10028-6 P690QL1 yog dab tsi?
Raws li cov tshuaj muaj pes tsawg leeg ntawm P690Q, P690QL1 paub txog kev txhim kho kev tswj hwm ntawm molten steel huv huv nrog kev txwv nruj ntawm cov khoom tsis zoo xws li phosphorus thiab sulfur, nrog rau kev ua kom zoo ntawm cov nplej ua kom zoo dua qub. Lub ntsiab lus "L1" qhia tias cov hlau tau txais L1-qib qis-kub toughness ntawv pov thawj, nrog Charpy kev cuam tshuam kev sim ua ntawm -40℃(raws li qhov yuav tsum tau muaj ntawm ASTM A517 Qib B).

Kev sib piv ntawm Weldability: A517 Qib B vs P690Q vs P690QL1 Phaj
ASTM A517 Qib B
ASTM A517 Qib B steel phaj nta cov pa roj carbon ntau sib npaug thiab tseem ceeb tshaj plaws rau kev tawg yooj yim. Preheating ntawm150-200 degreeyog qhov yuav tsum tau ua ua ntej welding, thiab qis - hydrogen vuam consumables yuav tsum tau saws. xeb thiab noo noo ntawm vuam grooves yuav tsum tau muab tshem tawm kom huv si. Ib qho teeb meem tseem ceeb yog qhov kev pheej hmoo siab ntawm kev rov ua kom tawg tom qab kev tshaj tawm -weld heat treatment (PWHT). Yog li ntawd, weld layout yuav tsum tau optimized thaum lub sij hawm tsim qauv kom txo tau cov residual kev nyuaj siab.
TS EN 10028-6 P690Q
P690Q steel phaj muaj cov pa roj carbon sib npaug. Lub preheating kub yuav tsum tau khaws cia ntawm100-180 degreenrog interpass kub tswj hauv qab 250 degree. High-lub zog qis- hydrogen vuam hlau thiab electrodes ua raws li EN ISO 16834-A yuav tsum sib phim. Cov txheej txheem vuam cov txheej txheem rau cov hlab ntsha siab yog tsim nyog rau kev tsim khoom, xa cov teeb meem kev tsim kho tsawg thiab kev siv tau zoo ntawm qhov chaw.
EN 10028-6 P690QL1
Vuam txoj kev xav tau rau P690QL1 feem ntau yog ua raws li cov P690Q, tab sis kev tswj nruj dua ntawm vuam cov khoom siv hluav taws xob yuav tsum tau tiv thaiv cov nplej coarsening nyob rau hauv tshav kub- thaj tsam cuam tshuam (HAZ) uas yuav degrade qis- kub toughness. Kev txias nrawm yog txwv tsis pub tom qab vuam; lub vuam yuav tsum tau them nrog asbestos daim ntaub kom txias qeeb kom lav qhov qis - qhov kub thiab txias kev ua tau zoo ntawm cov pob qij txha welded.

FAQ
A517 Qib B puas tuaj yeem ua tiav los ntawm kev khoov thiab ua kom txias?
Yog lawm, ASTM A517 Qib B tuaj yeem ua tiav los ntawm kev khoov thiab txias txias, tab sis nws yuav tsum tau ceev faj vim nws cov ultra- siab 100 ksi yam tsawg kawg nkaus lub zog.
Vim li cas A517 Qib B raug txwv rau tag nrho cov ncej-weld stress relief annealing?
A517 Qib B raug txwv lossis txwv tsis pub dhau tag nrho cov ncej-weld stress relief annealing vim thermal soaking degrades nws tshwj xeeb quenched thiab tempered microstructure, ua rau poob hnyav tensile thiab yield zog, txo toughness, thiab siab susceptibility rau reheat cracking nyob rau hauv lub tshav kub- cuam tshuam cheeb tsam.
A517 Qib B puas tuaj yeem hloov P690QL1 rau European cryogenic siab nkoj cov haujlwm?
Tsis yog, ASTM A517 Qib B tsis tuaj yeem hloov ncaj qha EN 10028-6 P690QL1 rau European cryogenic siab nkoj cov haujlwm yam tsis muaj kev rov ua dua- engineering, tshwj xeeb cov cai pom zoo, thiab cov kev sib tw pov thawj. Thaum ob qho tib si quenched thiab tempered (Q&T) siab - lub zog steels nrog 690 MPa yam tsawg kawg nkaus lub zog tawm los, lawv koom rau cov kev cai sib txawv thiab muaj qhov sib txawv ntawm qhov kub thiab txias.
