Lus piav qhia luv luv:
Hnub nyoog-hardening, tseem hu ua nag lossis daus hardening, yog txheej txheem kev kho cua sov uas txhim kho lub zog thiab hardness ntawm qee cov hlau, nrog rau cov hlau tsis muaj steel.Lub hom phiaj ntawm lub hnub nyoog-hardening yog ua kom cov nag lossis daus ntawm cov khoom zoo nyob rau hauv stainless hlau matrix, uas. ntxiv dag zog rau cov khoom.
Hnub nyoog-Hardening Stainless Hlau Forgings Bar:
Forgings yog cov khoom hlau zoo li tus txheej txheem forging, qhov twg cov khoom yog rhuab thiab ces hammered los yog nias rau hauv daim ntawv xav tau.Stainless steel forgings feem ntau xaiv rau lawv corrosion kuj, lub zog, thiab durability, ua rau lawv haum rau ntau yam kev siv, xws li aerospace. , roj thiab roj, thiab ntau dua.A bar-shaped forging yog ib hom kev forged hlau uas feem ntau muaj qhov ntev, ncaj, zoo ib yam li bar lossis pas nrig.Bars feem ntau siv rau hauv cov ntawv thov uas txuas mus ntxiv, ncaj nraim ntawm cov khoom. yog xav tau, xws li nyob rau hauv kev tsim kho ntawm cov qauv los yog raws li raw khoom rau kev ua ntxiv.

Dab tsi yog Precipitation Hardening Stainless Hlau?
Precipitation hardening stainless hlau, feem ntau hu ua "PH stainless hlau," yog ib hom stainless hlau uas dhau los ua cov txheej txheem hu ua nag lossis daus hardening lossis hnub nyoog hardening. Cov txheej txheem no txhim kho cov khoom siv kho tshuab ntawm cov khoom siv, tshwj xeeb tshaj yog nws lub zog thiab hardness. Qhov feem ntau nag lossis daus hardening stainless hlau yog17-4 PHN(ASTM A705 Qib 630), tab sis lwm qib, xws li 15-5 PH thiab 13-8 PH, kuj poob rau hauv pawg no.Precipitation hardening stainless steels feem ntau alloyed nrog cov ntsiab lus xws li chromium, npib tsib xee, tooj liab, thiab qee zaum txhuas. Qhov sib ntxiv ntawm cov alloying ntsiab no txhawb kev tsim cov precipitates thaum lub sij hawm kho cua sov txheej txheem.
Yuav ua li cas yog stainless hlau nag lossis daus hardened?
Lub hnub nyoog hardening stainless hlau koom nrog cov txheej txheem peb-kauj ruam. Thaum pib, cov khoom siv tau txais kev kho qhov kub-kub, qhov twg cov atoms yaj yaj, tsim cov tshuaj ib zaug. Qhov no ua rau muaj ntau lub microscopic nuclei lossis "zones" ntawm cov hlau. Tom qab ntawd, cov cua txias sai sai tshwm sim dhau qhov kev txwv tsis pub solubility, tsim kom muaj cov kua dej supersaturated nyob rau hauv lub xeev metastable.Nyob rau hauv cov kauj ruam kawg, cov tshuaj supersaturated yog rhuab mus rau nruab nrab kub, prompting nag lossis daus. Cov khoom yog ces khaws cia rau hauv lub xeev no kom txog rau thaum nws mus rau hardening. Ua tiav lub hnub nyoog hardening yuav tsum muaj cov alloy muaj pes tsawg leeg nyob rau hauv lub solubility txwv, kom ntseeg tau cov hauj lwm zoo ntawm cov txheej txheem.
Dab tsi yog hom nag lossis daus hardened steel?
Precipitation-hardening steels tuaj nyob rau hauv ntau hom, txhua tus tailored kom tau raws li tej kev ua tau zoo thiab daim ntawv thov yuav tsum tau. Feem ntau muaj xws li 17-4 PH, 15-5 PH, 13-8 PH, 17-7 PH, A-286, Custom 450, Custom 630 (17-4 PHNMod), thiab Carpenter Custom 455. Cov hlau no muaj kev sib xyaw ua ke ntawm lub zog siab, corrosion resistance, thiab hardness, ua rau lawv haum rau ntau yam industries xws li aerospace, automotive, kho mob, thiab tshuaj ua. Kev xaiv ntawm nag lossis daus-hardening steel nyob ntawm cov yam ntxwv xws li daim ntawv thov ib puag ncig, kev ua haujlwm ntawm cov khoom siv, thiab kev tsim khoom tshwj xeeb.
