Insimbi ye-DIN 30CrNiMo8

Insimbi ye-DIN 30CrNiMo8 iyinsimbi eyingxubevange eyenzelwe ukwakhiwa kwemikhiqizo eyenziwe.

• I-DIN 30CrNiMo8 impahla iyinsimbi eyodwa yesakhiwo enokuqina okuphakathi okudizayinelwe izingxenye zemisebenzi esindayo, ebonakala ngokunwebeka okuphezulu kanye nezakhiwo zamandla ezifinyelela ngaphezu kuka-1560 N//mm2 kumadiamitha amancane. Uma ithambe, ubulukhuni bufinyelela ubuningi. 248 HRB.
• Iphinde iphawuleka ngokumelana kwayo nemithwalo eguquguqukayo nemithelela.
• Kodwa-ke, ayilungele ukushisela futhi ekugcineni idinga ukushisisa okwengeziwe.

I-Gnee manje isitokwe ngebha eyindilinga yensimbi engu-30CrNiMo8 ukuze ithunyelwe ngokushesha enekhwalithi ethembekile nokutholakala kobubanzi obujwayelekile. Ibha eyindingilizi egoqwe ngokushisayo noma ephethwe ukushisa yomibili iyatholakala. Nansi eminye imininingwane ye-30CrNiMo8:

1. Ukunikezwa Kwebanga le-DIN 30CrNiMo8 Grade Steel

Ibha Eyindilinga engu-30CrNiMo8: ububanzi 20~130mm

Isimo: hot rolled; okwejwayelekile; Q+T

2. Ukucaciswa Okubalulekile kwe-30CrNiMo8 Material

3. I-DIN 30CrNiMo8 Chemical Composition

4. Izakhiwo ze-30CrNiMo8

• Izakhiwo (amanani amaphakathi) ezingeni lokushisa elizungezile

I-modulus yokunwebeka [103 x N/mm2]: 210

Ukuminyana [g/cm3]: 7.82

5. Ukwenziwa kwe-DIN 30CrNiMo8 Alloy Steel

Izinga lokushisa elishisayo lokubumba: 1050-850oC.

6. Ukwelashwa Kokushisa

• I-Soft Annealing

Shisisa ku-650-700oC, uphole kancane. Lokhu kuzokhiqiza ubulukhuni beBrinell obukhulu obungama-248.

• Ukujwayela

Izinga lokushisa: 850-880oC.

• Ukuqina

Yenza lukhuni kusuka ekushiseni okungu-830-880oC okulandelwa ukucisha uwoyela.

• Ukuthukuthela

Izinga lokushisa: 540-680oC.

7. Izicelo ze-30CrNiMo8 Round Bar

Okwezingxenye ezigcizelelwe unomphela ezinezingxenye ezinkulu eziphambanayo zobunjiniyela bezimoto nobunjiniyela. Ngokusebenza komnotho ngaphansi kwengcindezi eguquguqukayo, izingxenye kufanele zakhelwe amandla aphelele noma ukuqina.
