GCr15 inopisa yakakungurutswa simbi yakatenderedzwa mbariro

GCr15 isimbi yakajairika inoshandiswa kugadzira mabhora nemarin'i ekuberesa. Chigadzirwa chacho chine hunhu hweiyo yunifomu-kemikari kuumbwa, yakaderera muzana yezvinhu zvinokuvadza, kuchena kwepamusoro, yakagovaniswa carbide, yakanaka yemhando yepamusoro. Iyo zvakare ine hunhu hwehupamhi hwehupamhi hwepurasitiki, yakagadzikana kupisa-yekurapa mhando, yunifomu, uye kuomarara kwepamusoro, kusamira kwepamusoro, simba rekubata kuneta. Iyo ine yakanakisa machining midziyo mushure me spheroidize annealing. GB GCr15 inotakura simbi ndeye GB yakajairwa Alloy Bearing simbi, Ndeyemhando yepamusoro kabhoni, alloy chromium, manganese simbi. GB GCr15 zvivakwa ndeye chromium, manganese alloy simbi yakatarwa. GCr15 yakaenzana neAISI 52100, DIN 100Cr6. Mazhinji maapplication anogona kutsiva mumwe nemumwe.

Kemikari yakagadzirwa

C(％)	0.95～1.05	Si(％)	0.15～0.35	Mn(％)	0.25～0.45	P(％)	≤0.025
S(％)	≤0.025	Cr(％)	1.40～1.65

Mechanical Properties

Iwo emakanika zvivakwa zve annealed GB GCr15 inobereka simbi (yakajairika yesimbi) yakatsanangurwa mutafura pazasi:

Tensile	Yield	Bulk module	Shear modulus	Chiyero chePoisson	Thermal conductivity
MPa	Mpa	Gpa	Gpa		W/mK
520	415 Min	140	80	0.27-0.30	46.6

Kupisa kurapwa kwakabatana

• Kuiswa kweGCr15 Alloy ine simbi

Zvishoma nezvishoma kupisa kusvika 790-810 ℃ uye bvumira nguva dzakakwana, rega simbi inyatsopisa, Wobva watonhorera zvishoma nezvishoma muchoto. Nzira dzakasiyana-siyana dzekunamatira dzichawana kuomarara kwakasiyana.Simbi inotakura GCr15 ichawana Kuoma MAX 248 HB (kuoma kweBrinell).

• Kudzima uye tembiricha yeGCr15 Alloy inotakura simbi

Kupisa zvishoma nezvishoma kusvika 860 ° C, Zvino kudzimwa nemafuta kuwana 62 kusvika 66 HRc kuoma. Kupisa kwepamusoro: 650-700 ℃, kutonhorera mumhepo, kuwana kuoma 22 kusvika 30HRC. Kudzikira kwe tembiricha: 150-170 ℃, Kutonhorera mu ari, wana 61-66HRC kuoma.

• Basa rinopisa uye basa rinotonhora reGCr15 Alloy inotakura simbi

GB GCr15 simbi inogona kupisa ichishanda pa205 kusvika 538°C, GCr15 Inotakura simbi inogona kutonhora kushandiswa uchishandisa hunyanzvi hwakajairika mumamiriro ekunze kana kuti akajairwa.

Applications

GB GCr15 simbi inoshandiswa zvakanyanya kune akasiyana maapplication mune anoshandiswa kune mabearings mumachina anotenderera. Zvishandiso zvakajairika senge miviri yevharuvhu, pombi uye zvigadziriso, kuremerwa kwevhiri, mabhaudhi, mabhaudhi ane misoro miviri, magiya, injini yekupisa yemukati. Magetsi emagetsi, maturusi emuchina, matarakita, simbi yekutenderedza muchina, muchina unofinha, njanji, uye migodhi yemuchina wekufambisa shaft pabhora resimbi, roller uye shaft sleeve, nezvimwe.
