I-W6Mo5Cr4V2(M2) imivalo yentsimbi eshushu esongiweyo

I-M2 i-molybdenum series high-speed steel, ineenzuzo ze-carbide inhomogeneity encinci kunye nokuqina okuphezulu. Easy to overheating, kufuneka ukulawula ngokungqongqo ubushushu ukucima ubushushu, ukhuseleko olungqongqo ngakumbi unyango ubushushu. Ngenxa yobunzima bayo kunye nokunxiba, isetyenziswe ekwenzeni ukusika kunzima ukusika izixhobo zesixhobo. Intsimbi ye-M2 enesantya esiphezulu ene-carbide orientation inkulu, ngoko ke ukhuseleko olungqongqo ngakumbi kunyango lobushushu lulungele ukungcangcazela komngundo kunye nomthwalo womothuko.

Isixhobo se-SAE M2 seSixhobo seMpahla yeePropati zeMechanical Material

Ubunzima, i-Rockwell C (i-621 ° C, yacinywa kwi-1204 ° C): 62 HRC.

Ubunzima, i-Rockwell C (icinywe kwi-1204 ° C) ): 65 HRC

Yakhiwe ngeM2 HSS Steel impahla yentsimbi

Ekuqaleni, Ukufudumeza kwangaphambili ukuya kwi-650-750 ℃， Emva koko ubushushu ukuya kwiqondo lobushushu elibunjiweyo. Gxila kwi-1204 ° C, qinisekisa ubushushu ngokucokisekileyo. Emva koko qalisa ukukhwabanisa, iqondo lobushushu elibunjiweyo alikho ngaphantsi kwe-950 ℃. Emva kokupholisa, pholile ngokukhawuleza.

Unyango lobushushu lwe-SAE M2 Steel

• M2 HSS Steel Annealing

Ekuqaleni, Ubushushu obucothayo ukuya kuma-871℃, emva koko Ukupholisa kancinci ukuya kuma-538℃(1000℉) kwiziko lonyango lobushushu. Uze uphole emoyeni. Emva kokuqina kokuqina kwe-HBS: 255 Max.

• isixhobo M2 Steel Ukuqina

Intsimbi ye-M2 enokuqina okuphezulu kakhulu kwaye kufuneka yenziwe lukhuni ngokupholisa emoyeni ongashukumiyo. Ukusetyenziswa kwebhafu yetyuwa okanye isithando somlilo esilawulwayo siyanqweneleka ukunciphisa i-decarburization, kwaye ukuba ayifumaneki, ukupakisha ukuqina kwi-pitch coke echithiweyo kuyacetyiswa.
