DIN 30CrNiMo8 hlau

DIN 30CrNiMo8 steel yog ib qho hlau alloy uas tsim los rau hauv cov khoom siv wrought.

• DIN 30CrNiMo8 cov ntaub ntawv yog ib qho khoom siv hlau nrog nruab nrab hardenability tsim los rau cov khoom hnyav, uas muaj cov elasticity siab thiab lub zog muaj zog ncav cuag tshaj 1560 N / mm2 ntawm cov kab me me. Thaum nws yog softened, lub hardness ncav cuag max. 248 PAB.
• Nws kuj yog tus yam ntxwv los ntawm nws qhov tsis kam mus rau qhov sib txawv ntawm qhov sib txawv thiab cuam tshuam.
• Txawm li cas los xij, nws tsis zoo rau vuam thiab nws kawg yuav tsum tau preheating ntxiv.

Gnee tam sim no stocks 30CrNiMo8 steel puag ncig bar rau kev xa khoom tam sim nrog kev txhim khu kev qha zoo thiab muaj cov kab dav dav. Kub dov los yog kub kho round bar yog ob qho tib si muaj. Nov yog qee cov ntsiab lus ntawm 30CrNiMo8:

1. Kev muab khoom ntau ntawm DIN 30CrNiMo8 Qib Hlau

30CrNiMo8 Round Bar: txoj kab uas hla 20 ~ 130mm

Kev mob: kub dov; normalized; Q+T

2. Cov ntsiab lus tshwj xeeb rau 30CrNiMo8 Khoom

3. DIN 30CrNiMo8 Chemical Composition

4. 30CrNiMo8 Properties

• Cov khoom (qhov nruab nrab qhov tseem ceeb) ntawm qhov kub thiab txias

Modulus ntawm elasticity [103 x N/mm2]: 210

Qhov ceev [g/cm3]: 7.82

5. Forging ntawm DIN 30CrNiMo8 Alloy Steel

Kub tsim kub: 1050-850oC.

6. Kev kho cua sov

• Mos Annealing

Kub rau 650-700oC, txias maj mam. Qhov no yuav tsim qhov siab tshaj plaws Brinell hardness ntawm 248.

• normalizing

Kub: 850-880oC.

• Hardening

Harden los ntawm qhov kub ntawm 830-880oC ua raws li cov roj quenching.

• Tempering

Tempering kub: 540-680oC.

7. Daim ntawv thov ntawm 30CrNiMo8 Round Bar

Rau qhov kev ntxhov siab mus tas li nrog cov ntu loj hla rau kev siv tsheb thiab tshuab tshuab. Rau kev lag luam kev lag luam nyob rau hauv kev ntxhov siab loj heev, cov khoom yuav tsum tau tsim kom muaj lub zog zoo tshaj plaws los yog toughness.
