St52-3 yog German tus qauv qis- alloy siab{10}}lub zog steel engineering steel. St52-3 yog tsim raws li DIN17100 tus qauv. Tus qauv DIN17100 yog European tus qauv ISO630 luam tawm los ntawm European Coal thiab Steel Association thiab International Organization for Standardization (ISO). Kev xa khoom xa tuaj rau hauv lub xeev kub dov, nws lub zog tensile thiab cov ntsiab lus tawm los yog nws cov yam ntxwv tseem ceeb, thiab nws cov thickness ntau lawm yog 8mm-500mm tuab. St52-3 yog cov khoom siv feem ntau siv rau cov qauv hlau loj, kev tsim kho loj, thiab cov tshuab hnyav.
