302 Stainless hlau
302 yog ib qho kev hloov pauv ntawm 18 feem pua chromium / 8 feem pua nickel austenitic alloy, uas yog cov paub zoo tshaj plaws thiab feem ntau siv hauv tsev neeg stainless hlau. Alloy 302 yog cov pa roj carbon ntau dua me ntsis ntawm 304, feem ntau pom nyob rau hauv daim ntawv sawb thiab hlau. Nws yog ib qho tawv, qib ductile uas qhia tau hais tias muaj kev sib piv corrosion kuj, tsis yog-sib nqus, thiab tsis hardenable los ntawm kev kho cua sov. Alloy 302 feem ntau yog siv rau hauv nws cov mob annealed thiab muaj qhov yooj yim ntawm fabrication thiab formability.

Alloy 302 yog cov pa roj carbon ntau dua me ntsis ntawm304, feem ntau pom nyob rau hauv daim ntawv strip thiab hlau. Nws yog ib qho tawv, qib ductile uas qhia tau hais tias muaj kev sib piv corrosion kuj, tsis yog-sib nqus, thiab tsis hardenable los ntawm kev kho cua sov. Alloy 302 feem ntau yog siv rau hauv nws cov mob annealed thiab muaj qhov yooj yim ntawm fabrication thiab formability.
302 stainless hlau yog ib qho nyuaj heev, qib ductile uas qhia tau hais tias superior corrosion kuj. Nws yog qib tsis sib nqus uas tsis tuaj yeem ua kom tawv nqaij los ntawm kev kho cua sov. Nws yog feem ntau siv nyob rau hauv lub annealed mob thiab tau sau tseg rau nws yooj yim ntawm fabrication thiab formability.
Txawm hais tias ntau daim ntawv thov tau hloov mus rau 304 thiab 304L vim kev nce qib hauv kev siv tshuab melting, muaj, thiab nqi, Alloy 302 tseem siv ntau yam kev lag luam. Qee qhov piv txwv suav nrog:
Stamping
Khiav
Hlau txoj kev
Tsim los rau hauv txhua yam ntawm cov tshuab ntxhua khaub ncaws, cov dej ntws, cov ntxaij vab tshaus, thiab cables
Kev lag luam zaub mov thiab dej haus
Siab muaj cov ntawv thov
Kev siv tshuaj ntxuav tes los yog cryogenic

302 stainless hlau yog ib qho nyuaj heev, qib ductile uas qhia tau hais tias superior corrosion kuj. 302 SS yog non-magnetic, thiab nws tsis yog hardenable los ntawm kev kho cua sov. Thaum nws tuaj yeem ua haujlwm txias kom nce hardness, nws tseem yuav ua rau nws dhau los ua cov hlau nplaum me ntsis. Nws yog feem ntau siv nyob rau hauv lub annealed mob thiab tau sau tseg rau nws yooj yim ntawm fabrication thiab formability. Kev ua haujlwm txias yuav ua rau muaj zog ntxiv, txawm li cas los xij nws tswj tau qhov ductility thiab tuaj yeem rub, spun, thiab chim siab.
Hom 302 stainless hlau (AMS 5516) yog cov pa roj carbon ntau dua ntawm hom 304, thiab yog qhov zoo tagnrho rau kev siv xws li stamping thiab tsim cov khoom xws li cov ntxhua khaub ncaws tiaj tus los ntawm cov ntaub ntawv. Nws yog corrosion resistant nyob rau hauv ntau qhov chaw thiab nws cov qib siab ntawm corrosion kuj ua rau nws xaiv zoo rau kev lag luam khoom noj thiab dej haus. Peb muab 302 daim ntawv thiab phaj khoom (UNS S30200) ntau yam thicknesses rau koj cov ntawv tshwj xeeb.
