St52 steel (St52-3) yog LOW alloy structural steel qib ua raws li DIN 17100: 1980, lub npe tau muab pov tseg txij li xyoo 2004. Raws li German tus qauv DIN 17100, St52 steel yog muab faib ua St52-3U (1.0553) thiab St510.7-3N khoom. St 52 cov khoom siv tshiab yog S355, St52-3 lub npe tshiab yog S355J2 (1.0577), St52-3 U lub npe tshiab yog S355J0 (1.0553), thiab St52-3 N lub npe tshiab hauv EN 10025: 1993 yog S355J2G710 DIN tau hloov 10025-2: 2004.

Daim ntawv thov ntawm ST52-3 Steel
ST52-3 yog qib qis carbon structural steel feem ntau siv rau cov ntawv thov uas xav tau cov khoom siv kho tshuab zoo dua li S275 thiab S235 qib.
J2G3 txhais li cas?
Rau qib ST52-3 J2G3:
J2 txhais tau tias cuam tshuam lub zog 27J ntawm -20 degree
G3 txhais tau tias txoj kev deoxidation thiab normalized tus me nyuam
yield zog yog dab tsi?
Lub zog tawm los yog qhov siab tshaj plaws uas tuaj yeem siv tau ua ntej cov hlau pib deform mus tas li.Nws sawv cev rau qhov txwv elastic ntawm cov khoom. Yog tias muaj kev ntxhov siab tab sis tsis ncav cuag qhov txiaj ntsig, cov khoom siv yuav rov qab mus rau nws qhov qub tom qab qhov kev ntxhov siab raug tshem tawm.
