Imibuzo Ebuzwa Rhoqo (Imibuzo Ebuzwa Rhoqo) - Ipayipi Yentsimbi ye-API 5L X65 SSAW
Q: Yintoni umahluko phakathi kwe-API 5L X65 PSL1 kunye ne-PSL2?
A: I-PSL2 inemida engqongqo yokwakheka kweekhemikhali (i-C, i-P, i-S esezantsi), iimfuno zokuqina kwempembelelo ezinyanzelekileyo (27J @ 0°C), imida yokuqina okuphezulu (ubuninzi be-200 HV kwinkonzo ye-sour), kunye novavanyo olunzima ngakumbi olungonakalisiyo. I-PSL1 ifanelekile kwizicelo zemibhobho eziqhelekileyo ngaphandle kweemfuno zenkonzo ye-sour esezantsi okanye ye-sour. I-PSL2 icetyiswa kwizicelo zaselwandle, zenkonzo ye-sour, kunye nezicelo ze-sour esezantsi.
Q: Yintoni umahluko phakathi kweX65 kunye neX52?
A: I-X65 inamandla okuvelisa ubuncinane angama-450 MPa, ngelixa i-X52 ine-360 MPa. I-X65 inika amandla aphezulu angama-25%, okuvumela iindonga ezincinci, ubunzima obuphantsi, kunye noxinzelelo oluphezulu lokusebenza. I-X65 ikwanayo nemida engqongqo yokwakheka kweekhemikhali ukuze ibe namandla angcono kunye nokukwazi ukusebenza okumuncu.
