Daim ntawv thov piv txwv: Tom qab quenching thiab tempering, nws yog siv los tsim nruab nrab- nrawm thiab nruab nrab-load qhov chaw, xws li cov cuab yeej siv tshuab, ncej, cua nab, spline shafts, thimble tes tsho, thiab lwm yam, tom qab quenching thiab tempering, thiab siab -frequency deg quenching, nws yog siv los ua cov nto nrog siab hardness thiab kuj. Sib tsoo qhov chaw, xws li lub zog, ncej, spindles, crankshafts, spindles, lub tes tsho, pins, txuas rods, screws thiab ceev, noj li qub, thiab lwm yam., tom qab quenching thiab tempering ntawm nruab nrab kub, lawv yog siv los tsim hnyav{{8} }lub luag haujlwm, nruab nrab-kev cuam tshuam nrawm, xws li roj twj tso kua mis rotors, sliders, gears, spindles, dab tshos, thiab lwm yam, yog siv los tsim hnyav-lub luag haujlwm, qis- cuam tshuam, hnav-cov khoom tiv thaiv tom qab quenching thiab qis- qhov kub thiab txias, xws li cua nab, spindles, shafts, dab tshos, thiab lwm yam., carbon Tom qab nitriding kev kho mob, kis tau tus mob qhov loj thiab siab dua qis{{14} } kub cuam tshuam toughness yog tsim, xws li ncej, iav, thiab lwm yam.
4, HT150-grey cam khwb cia hlau
Daim ntawv thov piv txwv: iav lub cev lub cev, tshuab txaj, lub cev lub cev, lub tog raj kheej hydraulic, lub twj tso kua mis, lub cev valve, flywheel, lub tog raj kheej taub hau, pulley, bearing cover, thiab lwm yam.
5, 35-Cov khoom siv feem ntau siv rau ntau yam qauv thiab cov khoom sib khi
Cov yam ntxwv tseem ceeb: tsim nyog lub zog, zoo plasticity, siab txias plasticity, thiab siv tau weldability. Kev ntxhov siab ib nrab thiab kev kos duab tuaj yeem ua tiav hauv lub xeev txias. Tsawg hardenability, daim ntawv thov piv txwv tom qab normalizing los yog quenching thiab tempering: Haum rau kev tsim me me ntoo khaub lig- ntu ntu, qhov chaw uas tuaj yeem tiv taus cov khoom loj: xws li crankshafts, levers, txuas rods, hooks thiab loops, thiab lwm yam., ntau yam qauv qhov chaw, fasteners.
6, 65Mn- feem ntau siv caij nplooj ntoos hlav steel
Daim ntawv thov piv txwv: ntau yam tiaj tiaj tiaj, puag ncig springs, cushion springs, caij nplooj ntoos hlav caij nplooj ntoos hlav me me, thiab tseem tuaj yeem ua rau lub caij nplooj ntoos hlav, valve springs, clutch springs, brake springs, txias-rolled coil springs, circlips, etc. .
7, 0Cr18Ni9——The most commonly used stainless steel (American steel number 304, Japanese steel number SUS304)
Nta thiab daim ntawv thov: Nws yog qhov siv dav tshaj plaws los ua cov cua sov tsis muaj zog-cov hlau tsis muaj zog, xws li cov khoom noj khoom haus, cov cuab yeej siv tshuaj, thiab cov khoom siv hluav taws xob qub.
8, Cr12-feem ntau siv txias ua hauj lwm tuag steel (American steel tooj D3, Japanese steel tooj SKD1)
Cov yam ntxwv thiab kev siv: Cr12 steel yog dav siv dav siv ua haujlwm txias tuag steel, uas yog siab -carbon thiab siab -chromium ledeburite steel. Cov hlau muaj zoo hardenability thiab zoo hnav tsis kam; vim tias cov ntsiab lus carbon ntawm Cr12 steel yog siab li 2.3 feem pua, nws muaj kev cuam tshuam tsis zoo, yooj yim brittleness, thiab yooj yim tsim ntawm uneven eutectic carbides; Cr12 steel muaj qhov zoo hnav tsis kam, feem ntau yog siv los tsim cov punches txias, xuas nrig ntaus, blanking tuag, txias taub hau tuag, txias extrusion tuag, xuas nrig ntaus thiab tuag, laum lub tes tsho, ntsuas, uas yuav tsum muaj kev cuam tshuam tsawg dua thiab yuav tsum muaj siab hnav tsis kam Hlau kos duab tuag, stamping tuag, xov dov board, sib sib zog nqus nqus tuag thiab txias xovxwm tuag rau hmoov metallurgy, thiab lwm yam.
9, DC53-feem ntau siv txias ua hauj lwm tuag steel imported los ntawm Nyiv
Nta thiab daim ntawv thov: siab zog thiab toughness txias ua hauj lwm tuag steel. Tom qab kub kub tempering, nws muaj siab hardness, siab toughness thiab zoo hlau txiav kev ua tau zoo. Siv rau precision txias stamping tuag, kos duab tuag, xov dov tuag, txias blanking tuag, xuas nrig ntaus, thiab lwm yam.
