EN 10025-4 S460M steel phaj muaj cov khoom zoo weldability thiab cov khoom zoo zoo. S460M steel phaj tuaj yeem siv rau hauv cov qauv hlau lossis cov hlab ntsha lossis cov hlab ntsha siab. Tib lub sijhawm, EN 10025-4 S460M steel phaj kuj tuaj yeem siv hauv hiav txwv lossis lwm daim ntawv thov uas xav tau lub zog tensile siab.
EN 10025-4 S460M steel phaj yog ib qho kev xa khoom rau cov khoom siv thermo-mechanically dov weldable fine-grained structural steel. EN 10025-4 S460M steel phaj, S txhais tau tias cov qauv hlau, 460 txhais tau tias siab tshaj tawm lub zog, M txhais tau tias cov khoom xa tuaj.
