Qhov sib txawv tseem ceeb ntawm S500QL thiab S500QL1 steel daim hlau nyob rau hauv lawv qhov qis - qhov kub thiab txias yuav tsum tau muaj zog, tshwj xeeb tshaj yog qhov ntsuas kub: S500QL yuav tsum muaj qhov cuam tshuam tsawg kawg nkaus ntawm -40 degree, thaum S500QL1 xav kom nws ntawm qhov txias dua -60 degree, ua rau QL1 zoo dua rau kev ua kom muaj cua txias 0 thiab ob qho tib si txawm tias muaj kev sib tw. kub siab.
S500: Siab- lub zog cov qauv hlau nrog qhov tsawg kawg nkaus tawm lub zog ntawm 500 MPa.
Q: Qhia qhov kev xa khoom yog "Quenched thiab Tempered".
L: Qhia qhov kev ntsuam xyuas qhov cuam tshuam yog ua tiav ntawm qhov tsawg kawg ntawm -40℃(40 Joules).
L1: Qhia qhov kev ntsuam xyuas qhov cuam tshuam yog ua tiav ntawm qhov tsawg kawg nkaus ntawm -60℃(40 Joules), qhia tias qhov txias txias-tawv.
