Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4005 / 416

Machinability zoo heev:Ib qho ntawm cov hlau tsis zoo tshaj plaws, nrog rau kev ua tau zoo li ntawm 85% ntawm B1112 steel, siab dua 304 (45%) thiab 410 (55%), tso cai rau siab - machining ceev, lub neej ntev ntawm cov cuab yeej, thiab cov khoom zoo tshaj plaws.

Zoo Mechanical Properties:Nws tuaj yeem raug kho kom sov kom ua tiav lub zog zoo thiab ua kom tawv tawv thaum tswj kom txaus toughness rau feem ntau daim ntawv thov.

Nruab nrab Corrosion Resistance:Muab qhov tsim nyog tiv thaiv rau atmospheric tej yam kev mob, dej tshiab, tshuaj me me, thiab cov zaub mov acids, tab sis tsis haum rau hnyav corrosive ib puag ncig xws li marine los yog muaj zog acid kev pab cuam.

Sib nqus thiab Kub Treatable:Muaj zog sib nqus thiab teb zoo rau kev kho cua sov rau hardening.

 

Cov ntawv thov tseem ceeb:

Fasteners thiab Fittings:Screws, bolts, txiv ntseej, studs, thiab threaded Cheebtsam ua los ntawm kev siab -machining ceev.

Precision Cheebtsam:Gears, shafts, valve stems, twj twj tso kua mis, thiab ntsuas qhov chaw.

Phom thiab Defense:Cov khoom me me uas yuav tsum tau siv lub tshuab ua haujlwm nyuaj thiab lub zog zoo.

Kev kho mob:Cov cuab yeej phais thiab cov cuab yeej kho hniav yuav tsum tau ua kom zoo.

General Engineering:Cheebtsam qhov twg machinability yog qhov tseem ceeb tshaj qhov siab tshaj plaws corrosion kuj.

Automotive:Roj txhaj tshuaj Cheebtsam thiab sensor vaj tse.

 

Qhov txiaj ntsig tseem ceeb ntawm kev siv 416 (1.4005) tshaj 410 (1.4006) yog dab tsi?
Qhov tseem ceeb tshaj plaws yog machinability. 416 tshwj xeeb yog tsim los rau kev ua haujlwm dawb nrog cov sulfur ntxiv, tso cai rau kev txiav nrawm dua, lub neej ntev ntawm cov cuab yeej, cov khoom tiav zoo dua, thiab cov nqi tsim khoom qis dua piv rau 410. Txawm hais tias 410 muaj qhov zoo dua corrosion kuj thiab tuaj yeem ua tau zoo dua hardness (mus txog 55 HRC vs . 40 HRC rau 416), qhov kev xaiv ntau dua 416volt yog ntau dua qhov twg ntau lawm efficiency yog qhov tseem ceeb. Rau cov ntawv thov uas xav tau qhov siab tshaj plaws hardness thiab hnav tsis kam, 420 lossis 440C yuav tsim nyog dua.

 

Cov ntsiab lus ntawm leej faj cuam tshuam li cas rau corrosion kuj ntawm 416?
Cov ntsiab lus sulfur siab (Ntau dua lossis sib npaug li 0.15%) uas txhim kho kev ua haujlwm kuj tseem tsim cov manganese sulfide inclusions, uas tuaj yeem ua raws li qhov chaw pib rau pitting corrosion. Qhov no txo ​​qhov kev tiv thaiv corrosion tag nrho piv rau qib qis - cov qib sulfur martensitic zoo li 410 lossis 420. Yog li ntawd, 416 tsis pom zoo rau qhov chaw muaj corrosive heev, cov ntawv thov uas yuav tsum tau ua kom tiav qhov chaw siab, lossis qhov chaw yuav raug rau cov tshuaj chlorides, acids, los yog marine tej yam kev mob. Rau cov ntawv thov no, lwm cov qib uas muaj kev tiv thaiv corrosion zoo dua yuav tsum raug txiav txim siab.

 

Dab tsi yog cov lus qhia txog kev kho cua sov rau 416?
Kev kho cua sov rau 416 suav nrog:

Hardening:Austenitize ntawm 980-1030 degree, tuav lub sijhawm txaus, ces roj quench

Tempering:Kub tam sim ntawd tom qab quenching ntawm 540-650℃rau optimum toughness, los yog ntawm 150-370℃rau siab dua hardness

Tempering nyob rau hauv qhov ntau ntawm 370-540℃yuav tsum tau zam kom tsis txhob tempered martensite embrittlement

Annealing yog ua nyob rau ntawm 830-900℃nrog qeeb cua sov cua txias kom soften cov khoom rau siab tshaj machinability
