Qhov sib txawv ntawm Q460NC steel phaj thiab Q460C, lub thickness ntawm Q460NC steel phaj yog ntau tshaj 80
Qhov txawv ntawm Q460NC steel phaj thiab Q460C yog tias lub thickness ntawm Q460NC steel phaj yog ntau tshaj 80, thiab lub normalized dov phaj Q460NC steel phaj yog ib tug tsawg-alloy high-strength steel.Q hauv qib Q460NC sawv cev rau lub zog ntawm cov hlau.Cov tsiaj ntawv loj;460 sawv cev rau 460 MPa, mega yog 10 mus rau 6 lub zog, thiab Pa yog lub siab Pascal;Q460 txhais tau hais tias cov yas deformation tsuas yog tshwm sim thaum lub zog txhua yam ntawm cov hlau mus txog 460 MPa, uas yog, thaum lub zog sab nraud raug tso tawm, Hlau tsuas tuaj yeem tswj cov duab ntawm lub zog thiab tsis tuaj yeem rov qab mus rau nws qhov qub, uas muaj zog dua. zoo tib yam hlau.N sawv cev rau normalizing lossis normalizing dov, C-qib zoo yog C (qib muab faib ua C, D, E).
