301 (1.4310) piv rau 304 (1.4301) stainless hlau li cas?
301 muaj qis nickel (6-8% vs . 8-10.5%) thiab qis dua chromium (16-18% vs. 17.5-19.5%) dua 304, ua rau nws tsis tshua kim tab sis kuj me ntsis corrosion resistant. Txawm li cas los xij, 301 ua haujlwm nyuaj dua sai dua li 304, tso cai rau nws ua kom muaj zog ntau dua los ntawm kev ua haujlwm txias. Nyob rau hauv tag nrho cov mob hnyav, 301 tuaj yeem ua tiav lub zog tensile tshaj 1200 MPa, piv rau 304 uas feem ntau maxes tawm ib ncig ntawm 800 MPa. 301 yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov caij nplooj ntoos hlav thiab cov khoom siv uas xav tau lub zog siab, thaum 304 yog qhov zoo dua rau cov ntawv thov uas xav tau ntau tshaj corrosion kuj thiab formability.
Dab tsi yog qhov kev xav txog kev kho cua sov rau 301?
301 tsis yog hardenable los ntawm kev kho cua sov; nws lub zog yog ua tiav los ntawm kev ua haujlwm txias. Cov kev xav txog kev kho cua sov tseem ceeb muaj xws li:
Annealing:Thaum tshav kub kub rau 1010-1120 degree, tom qab ntawd dej quench lossis cua txias kom soften cov khoom
Stress Relieving:Tshav kub rau 250-400℃los txo cov kev ntxhov siab uas tsis muaj zog
Kev Kho Mob:1010-1120℃ua raws li qhov txias txias kom rov qab ua haujlwm corrosion
Tsis txhob ncua ntev ntawm 400-900℃ntau yam kom tsis txhob muaj kev puas tsuaj
Annealing yuav tsum tau ua ua ntej complex forming ua hauj lwm
Dab tsi yog qhov kev txiav txim siab vuam rau 301?
301 muaj qhov zoo weldability siv ntau txoj kev, tab sis yuav tsum tau saib xyuas:
Haum rau TIG, MIG, thiab tsis kam vuam
Muab cov hlau sib txuam (ER308, ER309) raug pom zoo
Cov txheej txheem hluav taws xob qis qis pab tswj kev tiv thaiv corrosion
Kev hnov mob tuaj yeem tshwm sim hauv 450-850 degree, yog li kev ua kom txias sai sai
Tom qab-weld kev kho cua sov tsis tas yuav tsum muaj rau feem ntau daim ntawv thov
Rau cov khoom siv ua haujlwm txias heev, yuav tsum tau siv annealing ua ntej vuam kom tsis txhob tawg
