ASTM A240 Qib 310S Kub Rolled Stainless Hlau Phaj Softened Thiab Descaled

General Properties

Alloy 310 (UNS S31000) yog ib qho austenitic stainless hlau tsim los siv rau hauv cov ntawv thov kub corrosion resistant. Cov hlau tiv thaiv oxidation mus txog 2010oF (1100oC) nyob rau hauv me me cyclic tej yam kev mob.

Vim tias nws cov chromium siab thiab cov ntsiab lus nickel nruab nrab, Alloy 310 yog resistant rau sulfidation thiab tuaj yeem siv rau hauv nruab nrab carburizing cua.

Qhov hnyav dua carburizing cua ntawm cov txheej txheem thermal feem ntau yuav tsum tau nickel alloys xws li 330 (UNS N08330). Alloy 310 tuaj yeem siv rau hauv me ntsis oxidizing, nitriding, cementing thiab thermal cycling daim ntaub ntawv, txawm hais tias, qhov siab tshaj plaws kev pab kub yuav tsum tau txo. Alloy 310 kuj pom kev siv hauv cov ntawv thov cryogenic nrog qis sib nqus permeability thiab toughness mus rau -450oF (-268oC). Thaum rhuab ntawm 1202 - 1742oF (650 - 950oC) cov hlau yog raug rau sigma theem nag lossis daus. Ib qho tshuaj annealing kev kho mob ntawm 2012 - 2102oF (1100 - 1150oC) yuav rov qab ua kom muaj zog.

310S (UNS S31008) yog qhov qis carbon version ntawm cov hlau. Nws yog siv rau kev yooj yim ntawm fabrication. 310H (UNS S31009) yog ib qho kev hloov kho carbon siab tsim los txhim kho kev nkag siab zoo. Feem ntau cov nplej loj thiab cov ntsiab lus carbon ntawm lub phaj tuaj yeem ua tau raws li 310S thiab 310H cov cai.

Alloy 310 tuaj yeem ua tau yooj yim welded thiab ua tiav los ntawm cov qauv kev tsim khoom hauv khw.
