20CrMnTi (H) inopisa yakakungurutswa simbi yakatenderedzwa mbariro

hunhu hwesimbi yakaomeswa alloy chishandiso simbi, yakanaka carburizing kupisa kupisa maitiro uye kuita kwesimbi pa ≤960 ℃ yakanaka zviyo chimiro, inowanzoshandiswa mukupisa kwenguva refu yekupisa carburizing tembiricha, zviyo zvakakura zvisingaite zvishoma zvakasara austenite mushure mekudzima, saka, iyo simbi ine simba rakawanda uye kupfeka kusagadzikana, yakanakisa kucheka kuita, iyo huru kuita uye 20CrMnTi uye 20CrNi simbi yakafanana. Kusimba kwesimba σ ≥1080MPa, goho simba σ ≥885MPa, kureba δ ≥10%, 45% kudzikiswa kwekuzvimba, kuoma kwemaitiro (kuoma kwesimba) α ≥69J/ cm, kuoma ≤207mm saizi kusvika 5mm saizi.

GB 20CrMnTi GB/T 3077 Mechanical

Mamichina e GB 20CrMnTi GB/T 3077 metare anotarisisa huwandu hwekubatsira kwechinhu uye kugadza hupenyu hwesevhisi hunogona kutarisirwa. Mechanical properties inoshandiswawo kubatsira kurongedza nekuona zvinhu.

Physical performance parameters ye GB 20CrMnTi GB/T 3077 inonyanya kuratidzwa ne density, poisson's ratio, thermal conductivity, chaiyo thermal capacity, coefficient of thermal expansion, modulus of elasticity, magetsi resistance value, etc.

Kupisa kurapwa kwakabatana

• Kuiswa kwe20CrMnTi Alloy Gearing steel

Zvishoma nezvishoma kupisa kusvika 790-810 ℃ uye bvumira nguva dzakakwana, rega simbi inyatsopisa, Wobva watonhorera zvishoma nezvishoma muchoto. Nzira dzakasiana dzekupinza dzichawana kuomarara kwakasiyana.Iyo 20CrMnTi Gearing simbi ichawana Kuoma MAX 248 HB (Brinell kuoma).

• Kudzima uye tembiricha ye20CrMnTi giya simbi

Kupisa zvishoma nezvishoma kusvika 788°C, Wobva waisa muchoto chekugezera munyu chengetedza 1191 ℃kusvika 1204 ℃。kudzima nemafuta kuwana 60 kusvika 66 Hrc kuoma. Kupisa kwepamusoro: 650-700 ℃, kutonhorera mumhepo, kuwana kuoma 22 kusvika 30HRC. Kudzika kwe tembiricha: 150-200 ℃, Kutonhorera mu ari, wana 61-66HRC kuoma.

• Basa rinopisa uye basa rinotonhora re20CrMnTi Alloy Gearing simbi

GB 20CrMnTi simbi inogona kupisa ichishanda pa205 kusvika 538°C, 20CrMnTi Bearing/Simbi yegiya inogona kutonhora ichishanda uchishandisa hunyanzvi hwemazuva ese mumamiriro ekudzika kana kuti akajairika.
