Cov ntaub ntawv siv hauv kev tsim khoomstamping tuagxws li steel, steel cemented carbide, carbide, zinc raws alloys, cov ntaub ntawv polymer, aluminium bronze, siab thiab qis melting point alloys thiab lwm yam.Feem ntau ntawm cov khoom siv hauv kev tsim cov stamping tuag yog cov hlau.Cov khoom siv feem ntau siv rau kev ua haujlwm ntawm qhov tuag yog: carbon hlau, tsis tshua muaj hlau hlau, siab carbon siab lossis nruab nrab chromium cuab yeej steel, nruab nrab carbon alloy steel, siab ceev steel, matrix steel thiab carbide, steel cemented carbide, lwm.

1. Tsawg-alloy cuab yeej steel

Tsawg-alloy cuab yeej steel yog ua raws li cov cuab yeej carbon steel nrog rau qhov sib ntxiv ntawm txoj cai ntawm cov ntsiab lus alloying.Piv nrog cov cuab yeej carbon steel, txo qhov nyiam ntawm kev tawg thiab quenching deformation, txhim kho hardenability ntawm steel, hnav kuj zoo dua.Cov hlau tsis tshua muaj hlau siv hauv kev tsim cov pwm yog CrWMn, 9Mn2V, 7CrSiMnMoV (code CH-1), 6CrNiSiMnMoV (code GD) thiab lwm yam.

2. Cov pa roj carbon steel

Ntau daim ntawv thov hauv pwm ntawm cov cuab yeej carbon steel rau T8A, T10A, thiab lwm yam, qhov zoo ntawm kev ua haujlwm zoo, pheej yig.Tab sis lub hardenability thiab liab hardness yog tsis zoo, kev kho cua sov deformation, tsis tshua muaj load-bearing muaj peev xwm.

3. High-speed steel

High-speed steel muaj qhov siab tshaj plaws hardness, hnav tsis kam thiab compressive zog ntawm pwm steel, siab load-bearing muaj peev xwm.Feem ntau siv rau hauv pwm yog W18Cr4V (code 8-4-1) thiab tsawg dua tungsten W6Mo5Cr4V2 (code 6-5-4-2, Tebchaws Asmeskas hom M2) thiab txhawm rau txhim kho lub zog ntawm kev txhim kho ntawm cov roj carbon vanadium high-speed steel. 6W6Mo5Cr4V (code 6W6 lossis qis carbon M2).High ceev steels kuj yuav tsum tau rov forging los txhim kho lawv cov carbide faib.

4. High-carbon nruab nrab-chromium cuab yeej steels

High-carbon nruab nrab-chromium cov cuab yeej steels siv rau pwm yog Cr4W2MoV, Cr6WV, Cr5MoV, thiab lwm yam, lawv cov ntsiab lus chromium tsawg, tsawg dua eutectic carbide, carbide faib, kev kho cua sov deformation me me, nrog zoo hardenability thiab dimensional stability.Piv nrog rau cov carbide segregation yog qhov hnyav heev-carbon siab chromium hlau, qhov kev ua tau zoo tuaj.

5. High-carbon high-chromium cuab yeej hlau

Feem ntau siv high-carbon high-chromium cov cuab yeej steel Cr12 thiab Cr12MoV, Cr12Mo1V1 (code D2), lawv muaj hardenability zoo, hardenability thiabhnav tsis kam, kev kho cua sov deformation yog me me, rau siab hnav tsis kam micro-deformation pwm steel, bearing muaj peev xwm thib ob tsuas yog high-speed steel.Tab sis carbide segregation yog qhov hnyav, yuav tsum tau rov ua dua (axial upsetting, radial drawing) hloov forging, thiaj li yuav txo tau qhov tsis sib xws ntawm carbide, txhim kho kev siv ntawm kev ua tau zoo.

6. Cemented carbide thiab steel cemented carbide

Lub hardness thiab hnav tsis kam ntawm cemented carbide yog siab dua li ntawm lwm yam pwm hlau, tab sis lub zog khoov thiab toughness tsis zoo.Cov cemented carbide siv rau pwm yog tungsten thiab cobalt, thiab rau cov pwm uas muaj kev cuam tshuam me me thiab siab hnav tsis kam, cov ntsiab lus qis cobalt cemented carbide tuaj yeem siv tau.Rau cov moulds siab, carbide nrog cov ntsiab lus cobalt ntau dua tuaj yeem siv.
