I-W6Mo5Cr4V2(M2) imigoqo eyindilinga yensimbi eshisayo egoqiwe

I-M2 iwuchungechunge lwensimbi ye-molybdenum enesivinini esikhulu, inezinzuzo ze-carbide inhomogeneity encane kanye nokuqina okuphezulu. Easy to overheating, kufanele ngokuqinile ukulawula quenching Ukushisa lokushisa, isivikelo esiqine kakhudlwana ukwelashwa ukushisa. Ngenxa yokuqina kwayo kanye nokugqokeka kwayo, esetshenziswa ekwenzeni ukusika okunzima kakhulu ukusika izinto zamathuluzi. Insimbi enesivinini esikhulu i-M2 ene-carbide orientation inkulu, ngakho ukuvikela okuqinile kokwelashwa kokushisa kulungele ukudlidliza kwesikhunta kanye nemithwalo yokushaqeka.

I-SAE M2 Tool Steel Material Mechanical Properties

Ukuqina, i-Rockwell C (i-621°C, icinywe ku-1204°C): 62 HRC.

Ukuqina, i-Rockwell C (icinywe ku-1204°C) ): 65 HRC

Yakhiwe ngensimbi yensimbi ye-M2 HSS

Ekuqaleni, i-Pre-Heating iye ku-650-750 ℃, Bese ukushisa kuya kumazinga okushisa okukhwabanisa. Gcoba ku-1204 ° C, qinisekisa ukushisa kahle. Bese uqala ukukhwabanisa, izinga lokushisa elihlanganisiwe alikho ngaphansi kuka-950 ℃. Ngemuva kokupholisa, pholisa kancane.

Ukwelashwa Kokushisa kwe-SAE M2 Steel

• I-M2 HSS Steel Annealing

Ekuqaleni, Shisisa kancane uye ku-871℃, bese Kupholile kancane uye ku-538℃(1000℉) esithandweni sokushisa ukushisa. Bese kuphole emoyeni. Ngemuva kokuqina kokuqina kwe-HBS: 255 Max.

• Ithuluzi le-M2 Ukuqina Kwensimbi

Insimbi ye-M2 enokuqina okuphezulu kakhulu futhi kufanele iqiniswe ngokupholisa emoyeni onganyakazi. Ukusetshenziswa kwebhavu likasawoti noma isithando somlilo esilawulwayo kuyathandeka ukuze kuncishiswe ukususwa kwe-carburization, futhi uma kungatholakali, ukuqiniswa kwephakethe ku-pitch coke esetshenzisiwe kuyaphakanyiswa.

• Ukucinywa kwe-HSS M2 Steel material

Ukucisha izinga lokushisa / ℃ | isithando somlilo sokugeza usawoti: 1204

Ukucisha izinga lokushisa / ℃ | isithando somlilo esilawulwayo: 1216

Isikhathi sokugcina ukushisa/min: 5 ~ 15
