JIS SPV490 JIS G3115 Mechanical Properties
JIS SPV490 JIS G3115 steel yog qhov zoo tagnrho rau kev tsim cov hlab ntsha siab vim nws muaj ntau yam zoo. Cov no suav nrog nws lub zog tshwj xeeb, zoo heev scalability, txhim khu kev qha weldability, thiab zoo corrosion kuj. Nws muaj peev xwm tiv taus qhov kub thiab txias thiab tsis tshua muaj kev tawg vim nws cov qib siab ntawm elongation. Cov hlau no tseem muaj peev xwm tiv taus oxidation thiab lwm yam kev xeb, uas ua rau nws zoo tagnrho rau kev siv hauv kev lag luam uas yuav tsum tau raug cuam tshuam rau huab cua hnyav thiab huab cua kub heev. Tsis tas li ntawd, nws muaj tus nqi qis dua piv rau lwm hom steels, ua rau nws muaj kev xaiv zoo dua rau cov nqi tsim nyog.
JIS SPV490 JIS G3115 cov khoom siv kho tshuab yuav tsum ua raws li cov txiaj ntsig tau muab rau hauv cov lus hauv qab no.

JIS SPV490 JIS G3115 Lub cev muaj zog
Lub cev muaj zog ntawm JIS SPV490 JIS G3115 suav nrog lub zog siab, qhov hnyav, ua haujlwm ntev, ductility thiab tsis kam tiv thaiv corrosion. Hlau, raws li peb txhua tus paub, muaj lub zog zoo txawm tias nws yog qhov hnyav. Qhov tseeb, qhov piv ntawm lub zog rau qhov hnyav rau steel yog qhov qis tshaj li lwm yam khoom siv hauv tsev muaj rau peb.
