s3 alloy steel s2 txawv
s3 alloy steel: lag luam wholesale thiab muag khoom SKS3 tsis yog -deformation roj steel, imported los ntawm Nyiv SKS3 alloy steel txias kos hlau chaw.
s2 alloy steel: 40Cr yog tus qauv steel naj npawb ntawm GB hauv Suav teb, 40Cr steel yog ib qho ntawm cov hlau siv dav tshaj plaws hauv kev tsim khoom siv tshuab. Nws muaj cov khoom zoo txhua yam, zoo kub tsis tshua muaj kev cuam tshuam toughness thiab tsis tshua muaj siab rhiab heev tom qab tempering. Steel hardenability yog zoo, dej quenching yuav quenched rau 28 ~ 60mm, roj quenching yuav quenched rau 15 ~ 40mm. Ntxiv nrog rau kev kho cua sov, cov hlau no tseem tsim nyog rau cyaniding thiab siab - zaus quenching kho. Thaum lub hardness yog 174 ~ 229HB, tus txheeb ze machinability yog 60%. Cov hlau yog tsim los ua cov yas pwm nruab nrab.
FAQ
Q: Koj puas muab S2 hauv qhov muag muag kom kuv tuaj yeem tshuab nws ua ntej hardening?
A: Yog. Peb nqa annealed Tshuag ntawm HB 180-220 kom yooj yim drilling thiab milling. Koj tuaj yeem tshuab koj lub taub hau hex los yog lub hau ntswj blanks ua ntej, ces xa lawv tawm rau hardening. Peb kuj muaj pre-hardened 28-32 HRC yog tias koj xav tau lub zog tam sim ntawd yam tsis muaj kev kho cua sov tag nrho.
Q: Ntev npaum li cas hneev lossis twist kuv yuav tau txais tom qab hardening ntev S2 bar?
A: Tsawg tsawg dua 0.05% hloov pauv yog tias koj ua raws li kev pom zoo cua-quench thiab npau taws. Rau 200 hli ntswj ntsia hlau shank, uas ua hauj lwm tawm mus txog 0.1 hli tag nrho runout. Cov neeg siv khoom feem ntau hla ncaj nraim rau tag nrho.
Q: Dab tsi yog qhov sib txawv ntawm S2 thiab S3 - Kuv puas tuaj yeem hloov ib qho rau lwm tus?
A: Tsis yog tiag. S3 (xws li SKS3) yog roj-hardening nrog ntau dua chromium thiab zoo hnav tsis kam, tab sis nws yog nkig ntau dua. S2 yog air-hardening thiab tougher - nws yuav siv tau zoo dua. Peb tau pom cov cuab yeej hloov pauv ntawm S3 rau S2 thaum lawv cov khoom hex khaws cia ntawm lub caj dab hauv qab torque.
Q: Koj puas tuaj yeem muab S2 hauv cov duab uas tsis yog puag ncig - piv txwv li, cov khoom lag luam tiaj tus lossis txawm tias ib qho kev cai hex profile?
A: Yog, peb zom cov kev cai profile rau ± 0.01mm. Rau hex wrench blanks, peb tuaj yeem xa cov duab ze-net nrog cov flats twb hauv av - koj tsuas yog txiav kom ntev thiab laum lub qhov. Txuag koj li 30% ntawm lub sijhawm milling ntawm thawj qhov kev ua haujlwm.
Q: Cov hlau no puas tuaj yeem tuav nws qhov nyuaj yog tias kuv siv nws hauv qhov sov-forming tuag ntawm 250 degree?
A: Nws yuav. S2 khaws txog 50 HRC txog 300 degree. Nyob rau ntawm 250℃intermittent, ntug sharpness nyob ruaj khov. Yog tias koj qhov tuag khiav tsis tu ncua saum 300 degree, peb xav qhia qib siab dua qhov tawv tawv zoo li H13 - tab sis rau feem ntau cov cuab yeej siv tes thiab cov ntawv thov stamping, S2 npog ntau yam.
Q: Koj puas muab tag nrho traceability thiab cov ntaub ntawv xeem thib peb rau cov neeg siv khoom siv tsheb lossis cov cuab yeej kho mob?
A: Yog lawm, peb muab cov ntaub ntawv ntsuam xyuas zeb nrog tshuaj lom neeg, hardness, thiab UT cov txiaj ntsig. Yog tias koj cov neeg siv khoom xav tau kev pov thawj ywj pheej, peb tuaj yeem npaj SGS lossis BV tshuaj xyuas ntawm qhov chaw. Daim ntawv pov thawj EN 10204 3.2 yog muaj rau kev xa tawm, thiab peb tau xa mus rau ntau lub tuam txhab tsheb tier-1 nrog cov ntaub ntawv ntawd.
