Cov khoom siv twg yog 1.4112?cov
Cov khoom siv 1.4112 yog martensitic stainless hlau tseem hu ua X90CrMoV18 lossis AISI 440B, nws tus yam ntxwv los ntawm nws cov ntsiab lus siab carbon thiab chromium, uas muab nws zoo heev hardness, hnav tsis kam thiab zoo corrosion kuj. Lub hardenable steel no feem ntau yog siv rau hauv cov ntawv thov xws li cov hniav riam, cov cuab yeej phais thiab cov cuab yeej tsim khoom, vim nws muaj peev xwm ua tau siab hardness (txog 60 HRC) thiab tuav cov npoo ntse.
Cov khoom siv 1.4125 sib npaug li cas?cov
440C stainless hlau yog qib martensitic uas tuaj yeem kho cua sov txog 57-60 HRC. Qib no raug xaiv raws li 1.4125 lossis X105CrMo17 raws li EN tus qauv thiab UNS S44004 raws li UNS tus qauv.
Dab tsi yog 1.4123 stainless hlau sib npaug?cov
Qib 1.4123 (AISI 420 MOD), lwm txoj hauv kev rau CRONIDUR 30®, yog ib qho nyuaj heev martensitic stainless hlau nrog zoo abrasion tsis kam thiab corrosion kuj ntau dua li ntawm 17% Cr - 1% C ntau yam (hom 440C).

1.4112 vs . 1.4125 stainless hlau: Corrosion kujcov
1.4112 (AISI 440B) muaj kev tiv thaiv corrosion zoo dua li 1.4125 (AISI 440C) vim tias nws muaj cov ntsiab lus qis me ntsis thiab feem ntau muaj ntau dua vanadium / molybdenum, uas txhim kho nws cov khoom. Txawm li cas los xij, 1.4125 muaj zog dua thiab hnav tsis kam. Ob leeg yog martensitic stainless hlau. 1.4112 muaj qee cov kua qaub tiv thaiv thiab yog qhov tsim nyog rau kev siv dav dav uas muaj kev txhawj xeeb, thaum 1.4125 yog qhov tsim nyog rau cov ntawv txiav txiav siab.
1.4112 thiab 1.4125 stainless hlau: Hardnesscov
Ob leeg 1.4112 (440B) thiab 1.4125 (440C) yog high-carbon martensitic stainless hlau paub rau lawv zoo heev hardness, tab sis 1.4125 (440C) ua tiav hardness ntau dua (txog ~ 60 HRC) vim nws cov ntsiab lus carbon ntau dua piv rau 1.4112 (440B).
1.4112 thiab 1.4125 stainless hlau: Weldabilitycov
Ob leeg 1.4112 (440B) thiab 1.4125 (440C) yog high-carbon martensitic stainless hlau nrog tsis zoo inherent weldability vim lawv nyiam huab cua-harden, tsim nkig martensite nrog kev pheej hmoo ntawm kev tawg; Txawm li cas los xij, vuam yog ua tau nrog nruj preheating (kwv yees 260 degrees / 500 degrees F) thiab nws kim heev tom qab vuam kev kho cua sov (annealing ntawm 732–760 degrees / 1350–1400 degrees F rau ob peb teev, ua raws li los ntawm qeeb qhov cub txias) los tiv thaiv tawg thiab restore zog, txawm hais tias nws yog feem ntau zam rau lwm txoj kev.
Puas yog 440C stainless hlau xeb yooj yim?cov
