Cov kab nrib pleb yog tsim, qhov txias bending plasticity yog nruab nrab, lub machinability yog zoo tom qab tempering los yog quenching thiab tempering, tab sis lub weldability tsis zoo, thiab tawg yooj yim tshwm sim. Ua ntej vuam, nws yuav tsum tau preheated rau 100 ~ 150 degree C. Carbonitriding thiab high zaus nto hardening yog nqa tawm. Daim ntawv thov piv txwv: Tom qab quenching thiab tempering, nws yog siv los tsim nruab nrab-ceev thiab nruab nrab-load qhov chaw, xws li cov cuab yeej siv tshuab, shafts, worms, spline shafts, thimble tes tsho, thiab lwm yam..Tom qab quenching thiab tempering thiab high-frequency nto quenching, nws yog siv los tsim cov khoom uas muaj qhov tawv tawv thiab hnav tsis kam, xws li lub zog, shafts, lub ntsiab ncej, crankshafts, mandrels, tes tsho, pins, txuas rods, screws thiab txiv ntseej, noj li qub, thiab lwm yam. Tom qab quenching thiab nruab nrab kub. tempering, nws yog siv los tsim hnyav-duty, nruab nrab-ceev cuam tshuam qhov chaw, xws li roj twj tso kua mis rotors, sliders, zog, spindles, dab tshos, thiab lwm yam. Tom qab quenching thiab low-temperature tempering, nws yog siv los tsim hnyav hnyav, Tsis tshua muaj kev cuam tshuam, resistant Sib tsoo qhov chaw, xws li cab, spindles, shafts, dab tshos, thiab lwm yam, yog carbonitrided los tsim kis tau tus mob qhov chaw nrog loj loj thiab siab kub tsis tshua muaj kev cuam tshuam toughness, xws li shafts, zog, thiab lwm yam.
4. HT150 — grey cam khwb cia hlau. Daim ntawv thov piv txwv: iav lub thawv, tshuab txaj, lub thawv, hydraulic lub tog raj kheej, twj tso kua mis, valve, flywheel, lub tog raj kheej taub hau, pulley, bearing cover, thiab lwm yam.
5. 35 ——Cov khoom siv rau ntau yam qauv thiab fasteners.Main nta: tsim nyog lub zog, zoo plasticity, siab txias plasticity thiab txais weldability. Kev ntxhov siab hauv zos thiab kev kos duab hlau tuaj yeem ua tau nyob rau hauv lub xeev txias. Tsawg hardenability, siv tom qab normalizing los yog quenching thiab tempering. Daim ntawv thov piv txwv: Nws yog qhov tsim nyog rau kev tsim cov khoom me me thiab qhov chaw uas tuaj yeem nqa cov khoom loj: xws li crankshafts, levers, txuas rods, shackles, thiab lwm yam., ntau yam qauv thiab fasteners.
6. 65Mn — Feem ntau siv caij nplooj ntoos hlav steel. Daim ntawv thov piv txwv: me me ntau yam tiaj tus thiab puag ncig lub caij nplooj ntoos hlav, lub tog raj kheej, lub caij nplooj ntoos hlav caij nplooj ntoos hlav, kuj tuaj yeem ua rau lub caij nplooj ntoos hlav, lub valve springs, clutch reeds, nres springs, txias coil springs, circlips, thiab lwm yam.
7. 0Cr18Ni9—Qhov feem ntau siv stainless hlau (US steel No. 304, Japanese steel No. SUS304). Nta thiab daim ntaub ntawv: Raws li feem ntau dav siv stainless hlau kub-resistant steel, xws li cov khoom noj khoom haus, cov khoom siv tshuaj, thiab cov khoom siv.
8. Cr12 —— Feem ntau siv txias ua hauj lwm tuag steel (American steel qib D3, Japanese steel qib SKD1). Cov yam ntxwv thiab daim ntawv thov: Cr12 steel yog dav siv txias ua hauj lwm tuag steel, uas yog ib tug siab carbon thiab siab chromium hom ledeburite steel. Cov hlau muaj zoo hardenability thiab zoo hnav tsis kam; vim tias cov ntsiab lus carbon ntawm Cr12 hlau yog siab li 2.3 feem pua, qhov cuam tshuam toughness tsis zoo, nws yog ib qho yooj yim rau nkig, thiab nws yog ib qho yooj yim los tsim uneven eutectic carbides; Cr12 steel yog vim muaj kev hnav zoo, nws feem ntau yog siv los tsim cov punches txias, punches, blanking dies, txias taub hau tuag, txias extrusion tuag, xuas nrig ntaus thiab tuag, tho lub tes tsho, ntsuas uas yuav tsum tau hnav tsis kam nrog tsawg cuam tshuam. , hlau kos duab tuag, stamping tuag, xov dov daim hlau, sib sib zog nqus nqus tuag thiab txias nias tuag rau hmoov metallurgy, thiab lwm yam.
