I-Q345D ishidi lensimbi eligoqiwe elishisayo

Insimbi ye-GB/T1591 Q345D izokwenziwa ukuhlolwa okunomthelela kwe-charpy V-notch ngaphansi kokususa u-20 centigrade. Abakhiqizi abaningi beziqukathi bakha lawa mandla aphezulu okudonsa kanzima ukuze benze iziqukathi zasolwandle ezingasetshenziswa ekujuleni kolwandle.

Impahla Mechnical ye-Q345D low alloy structural steel:

Ubukhulu (mm)
Q345D	≤ 16	> 16 ≤ 35	> 35 ≤ 50	>50
Amandla esivuno (≥Mpa)	345	325	295	275
Amandla okuqina (Mpa)	470-630

Ukwakheka kwamakhemikhali kwe-Q345D insimbi yesakhiwo ephansi ye-alloy (Ukuhlaziywa Kokushisa Okuphezulu%)

Izakhi zamakhemikhali eziyinhloko ze-Q345D

Izidingo Zobuchwepheshe Nezinsizakalo Ezengeziwe:
♦ Ukuhlolwa okunomthelela kwezinga lokushisa eliphansi
♦ Ukusika nokushisela ngokwezidingo zabasebenzisi
♦ Ukuqiniswa okwengeziwe kwezinye izakhi zamakhemikhali eziqukethwe
♦ Isitifiketi sokuhlolwa se-Orginal Mill esikhishwe ngaphansi kwe-EN 10204 FORMAT 3.1/3.2
♦ Ukuhlolwa kwe-Ultrasonic ngaphansi kwe-GB/T2970,JB4730,EN 10160,ASTM A435,A577,A578
