Izakhiwo Zemishini

AH36, DH36, kanye ne-EH36zonke ziyizinsimbi ezinamandla amakhulu ezinezifanayoamandla okukhiqiza okungenani angu-355 MPafuthiamandla okudonsa asukela ku-490 kuya ku-620 MPa.

Izakhiwo Ezijwayelekile Zemishini:

• Amandla Okukhiqiza:≥ 355 MPa

• Amandla Okudonsa:490–620 MPa

• Ukwelulwa (ngama-50 mm):≥ 21%

• Ubulukhuni (HB):170–220

Umehluko oyinhloko phakathi kwabo useku-ukuqina komthelela, kulinganiswa ngokuhlolwa kwe-Charpy V-Notch (CVN) emazingeni okushisa ahlukene:

• I-AH36 ihlolwe ku-0°C.

• I-DH36 ihlolwe ku--20°C.

• I-EH36 ihlolwe ku--40°C.

Uma izinga lokushisa lokuhlola liphansi, kulapho ikhono lensimbi lokugcina ukuqina nokuvimbela ukuphuka okuqhekeka ezindaweni ezibandayo likhula khona.
