420J1 420J2 umucu wensimbi engagqwali
Incazelo emfushane:
Imichilo yensimbi engagqwali engu-420J1 kanye ne-420J2 iyizinhlobo ezimbili ezivamile zezinto zensimbi engagqwali eziyingxenye yochungechunge lwensimbi engagqwali ye-martensitic. Zinomehluko othile ekwakhiweni kwamakhemikhali kanye nezici. Nasi isifinyezo esifushane saleso naleso:
1. Umugqa wensimbi engagqwali we-420J1: I-420J1 iyinsimbi engagqwali engenakhabhoni ephansi enobulukhuni namandla aphezulu. Ukwakheka kwayo kwamakhemikhali kuvame ukufaka cishe i-carbon engu-0.16-0.25%, cishe i-chromium engu-1%, kanye nenani elincane le-molybdenum. I-420J1 inikeza ukumelana okuhle nokugqwala, ukusebenza kahle kokusika, kanye nezakhiwo zokugaya. Ivame ukusetshenziswa ekwenzeni imimese, izinsimbi zokuhlinza, izingxenye zemishini, kanye nezinye izinhlelo zokusebenza ezingagugi.
2. I-420J2 steel strip: I-420J2 iyinsimbi engagqwali esezingeni eliphakathi enobulukhuni obuphezulu kanye nokumelana nokuguguleka. Ukwakheka kwayo kwamakhemikhali kuvame ukuqukethe cishe i-carbon engu-0.26-0.35% kanye ne-chromium engaba ngu-1%. I-420J2 inokuqukethwe okuphezulu kwekhabhoni uma kuqhathaniswa ne-420J1, okuholela ekuqineni okukhulu kanye nokusebenza kokusika. Ivame ukusetshenziswa ekwenzeni imimese, ama-blade, izinsimbi zokuhlinza, izipilingi, kanye nezinye izingxenye zemishini.
