St 52-3 yog German tus qauv qes-alloy High-zog steel engineering hlau. St 52-3 yog tsim raws li tus qauv DIN17100. Tus qauv DIN17100 yog European txheem ISO630 luam tawm los ntawm European Coal thiab Hlau Koom thiab International koom haum rau cov qauv (ISO). Cov xwm txheej xa tawm hauv lub xeev kub-lub xeev, nws cov lus qhia lub zog yog nws cov cwj pwm tseem ceeb yog 8 hli {9} hli tuab. St 52-3 yog cov khoom siv uas siv tau rau cov qauv hlau loj, kev tsim kho loj, thiab tshuab hnyav.
