CM690 nga kaho porotaka tira wera

Koeke CM690, He aha te Hanga Matū o GB CM690 GB/T 18669? Te Hanga matū o te CM690 Steel, CM690 taonga maitai, CM690 waro Steel, GB maitai pereti Kaiwhakarato i Japan, GB maitai pepa Kaihoko, GB maitai Utu, GB Ōrite maitai, GB maitai kaiwhakarato i Haina, GB maitai Hainamana kōeke ōrite, GB CM690 GB /T 18669 maitai Whakatakotoranga

Ko te kaha tuku te tepe hua o GB CM690 GB/T 18669 i te wa e tuku ana, ara, ko te ahotea e atete ana i te huringa moroiti-kirihou. Ko te kaha o waho ka nui ake i te kaha tuku ka kore e taea e nga waahanga GB CM690 GB/T 18669 e kore e taea te whakaora. He iti ake i tenei, ko nga waahanga GB CM690 GB/T 18669 ka hoki ki te ahua taketake.
Ko te kaha o te kaha te uara nui o te whakawhiti mai i te rerekeetanga kirihou rite ki te whakakino kirihou i te rohe. Koia hoki te kaha ki te kawe kawenga o GB CM690 GB/T 18669 i raro i te mānukanuka. Ko te kaha o te tensile ko te parenga e tohu ana i te nui o te rerekee o te ahua kirihou o te GB CM690 GB/T 18669. Ko te rerekeetanga o nga tauira tensile he rite i mua i te mau i te ahotea teitei, engari kei tua atu i tera, ko te GB CM690 GB/T 18669 ka timata ki te kaki, ara ko te deformation concentrate.

GB CM690 GB/T 18669 Tinana

Ko nga ahuatanga a-tinana o GB CM690 GB/T 18669 te nuinga o te uhi i te modulus o te elasticity, te whakarea o te roha waiariki, te kawe waiariki, te kaha waiariki motuhake, te uara parenga hiko, te kiato, te ōwehenga o te paihana, aha atu.

Te pāmahana (°C)	Modulus o te elasticity (GPa)	Ko te tau toharite o te roha waiariki 10-6/(°C) i waenga i te 20(°C) me	Te kawe werawera (W/m·°C)	Te kaha waiariki motuhake (J/kg·°C)	Te parenga hiko motuhake (Ω mm²/m)	Kiato (kg/dm³)	Ko te whakarea o Poisson, ν
