Puas yog 301S81 zoo ib yam li AISI 631 stainless hlau?
Tsis yog, 301S81 tsis zoo ib yam li AISI 631 stainless hlau-301S81 yog siab -lub zog txias-rolled mob ntawm AISI 301 austenitic stainless hlau, thaum AISI 631 yog nag lossis daus-hardening-7 qib sib txawv ntawm cov khoom sib txawv (PH)
301S81 stainless hlau yog dab tsi?
301S81 stainless hlau belongs rau EN 10088 / EN 10151 tus qauv txheej txheem, qhov "S81" qhia txog qhov siab -lub zog txias- ua haujlwm ntawm qib 1.4310 (AISI 301).
Puas yog 301S81 stainless hlau hlau nplaum tom qab ua haujlwm txias?
Yog lawm, 301S81 stainless hlau dhau los ua ib feem los ua kom muaj zog sib nqus tom qab ua haujlwm txias vim muaj kev cuam tshuam -induced martensite tsim, tsis zoo li tshuaj -annealed austenitic qib.
Dab tsi yog 301S81 stainless hlau siv rau?
301S81 stainless hlau yog dav siv nyob rau hauv daim ntawv thov uas yuav tsum tau muaj zog thiab zoo elasticity, xws li springs, clips, railway Cheebtsam, conveyor siv, thiab structural txias- tsim qhov chaw.
Dab tsi yog qhov txawv ntawm 301S81 thiab 304 stainless hlau?
Piv nrog 304 stainless hlau, 301S81 muaj zog tensile ntau dua (feem ntau> 1,500 MPa tom qab ua haujlwm txias) tab sis qis dua corrosion thiab formability vim nws cov ntsiab lus qis nickel.
Puas yog 301S81 stainless hlau haum rau cov springs thiab txias - tsim qhov chaw?
Yog lawm, 301S81 stainless hlau yog tshwj xeeb tshaj yog haum rau springs thiab txias - tsim qhov chaw vim nws txias - ua hauj lwm mob muab siab yield zog, zoo heev springback, thiab zoo qaug zog.
