17-7PH Insimbi engagqwali

17-7PH Ibha yensimbi engagqwali, 17-7PH ipuleti lensimbi

I-17-7Ph iwuhlobo lwemvula ye-Austenitic-Martensite eqinile eyakhiwe ngesisekelo sensimbi engagqwali ku-18-8CrN, okuyinsimbi engagqwali engu-631. Ngemuva kokwelashwa kwesisombululo esiqinile, insimbi engagqwali engu-17-7ph izoba izicubu ze-Austenite ezingazinzile, bese ipholisa ukuze ikhiphe i-carbide, bese kwenziwa ukuguqulwa kwe-Martensite. Iningi lamathishu lizoguqulwa libe yi-Martensite ene-carbon tempered Martensite enokuqina okungcono. Ukumelana nokugqwala kwe-17-7PH kungcono kunokwensimbi evamile ye-Martensitic.

I-17-7PH ibonakala ngamandla amakhulu nobulukhuni, izakhiwo ezinhle kakhulu zokukhathala, ukumelana nokugqwala okuhle kanye nokuhlanekezela okuncane ekwelapheni ukushisa ngemva kokwelashwa kokushisa. Izakhiwo zokubumba nokunwebeka kwe-annealed 17-7PH kufana ne-301. Ngaphansi kwezimo zokwelashwa kokushisa kwe-TH1050 ne-RH950, ukumelana nokugqwala kwe-631 kungcono kunezinsimbi ezingenasici eziqinile eziqinile (ezifana ne-410, 420 kanye ne-431), kodwa hhayi kuhle njenge-304. Ngemuva kokwelashwa kokushisa, ukumelana nokugqwala kwe-CH900 kufana ne-304 ezindaweni eziningi.
