AISI 305 UNS S30500 1.4303 stainless hlau yog muaj 17 feem pua mus rau 19 feem pua chromium, 12 feem pua carbon, 2 feem pua siab tshaj plaws manganese, 10 feem pua rau 13 feem pua nickel nrog cov kab ntawm phosphorus sulfur thiab silicon, nrog qhov sib npaug yog hlau. Nws tau tsim los rau siab tshaj plaws formability, nthuav tawm lub zog zoo thiab corrosion kuj. Qib 305 muaj qhov ua haujlwm qis tshaj plaws thiab cov nqi zog ntawm tag nrho cov austenitic stainless hlau. Qhov kev ua haujlwm qis qis no ua rau kev ua haujlwm txias yog ib qho ntawm cov qauv tsim muaj zog ntawm 305.
International sib npaug
| Mark | Analogue | W. Nr. | Aisi Uns | En | Kev txiav txim |
|---|---|---|---|---|---|
| 1.4303 | S30500 | Kev xa khoom los ntawm Tshuag, hauv Tshuag |
| Daim ntawv thov | Txhua daim ntawv thov uas yuav tsum tau ua kom siab tshaj plaws xws li spun los yog sib sib zog nqus nqus eyelets, chim, plhaub, txias taub hau rivets lossis screws yuav ua haujlwm zoo. |
| Machineability | Kev qeeb qeeb thiab hnyav pub yog pom zoo los tawm tsam cov khoom siv nyiam glaze thaum lub tshuab ua haujlwm. |
| Vuam | Feem ntau ntawm cov kev sib xyaw ua ke thiab kev tawm tsam tuaj yeem siv tau ntawm no. Filler hlau, yog tias tsim nyog, yuav tsum yog AWS E/ER308. Oxyacetylene vuam tsis pom zoo. |
| Kub Ua Haujlwm | Forging, taub hau thiab lwm yam kev ua haujlwm kub yuav tsum ua raws li cov cua kub sib xws rau 2100-2300 degree F (1149-1260 degree ). Kev ua kom txias ceev yog tsim nyog kom muaj qhov siab tshaj plaws corrosion nyob rau hauv cov khoom tiav. |
| Ua haujlwm txias | Kev ua haujlwm txias yog ib qho ntawm cov qauv tsim muaj zog ntawm no alloy. Nws tuaj yeem kos, spun, taub hau thiab blanked yooj yim vim feem ntau ntawm nws qhov qis ua haujlwm hardening tus nqi. |
| Annealing | 1850-2050 degree F (1010-1121 degree ) tom qab txias txias. |
Cov alloy no tsis teb rau kev kho cua sov. Kev ua haujlwm txias yuav ua rau muaj zog ntxiv thiab lub zog.
Tus Thawj Coj Tsim Nta
Ib qho ntawm feem ntau siv los nag lossis daus hardening qib hauv kev lag luam. Thaum mos thiab ductile nyob rau hauv cov tshuaj annealed mob, nws muaj peev xwm ntawm high zog nrog ib tug los nag los yog kev laus kev kho mob. Cov yam ntxwv los ntawm kev ua haujlwm zoo corrosion, siab harness, toughness thiab lub zog.
