Insimbi Engagqwali 17-4PH-SUS630
Amagama Okuhweba Ajwayelekile:17-4ph,S51740,SUS630,0Cr17Ni4Cu4Nb,05Cr17Ni4Cu4Nb,W. Nr./EN 1.4548
I-17-4 i-stainless i-martensitic eqinisa iminyaka yobudala ehlanganisa amandla aphezulu nokumelana nokugqwala kwensimbi engagqwali.Ukuqina kufinyelelwa ngesikhathi esifushane, ukwelashwa okulula kwezinga lokushisa eliphansi.Ngokungafani nensimbi evamile ye-martensitic engagqwali, njengohlobo 410, 17-4 iyakwazi ukushisela.Amandla, ukumelana nokugqwala kanye nokwenza lula kungenza i-17-4 ingabi nebala ithathelwe indawo engabizi kakhulu yezinsimbi zekhabhoni ezinamandla aphezulu kanye namanye amamaki angenabala.
Esikhathini sokushisa kwesisombululo sokwelapha, i-1900 ° F, insimbi i-austenitic kodwa ishintsha ibe isakhiwo se-carbon martensitic ephansi ngesikhathi sokupholisa ekamelweni lokushisa.Lokhu kuguqulwa akukaqedi kuze kube yilapho izinga lokushisa lehla liye ku-90°F.Ukushisisa okulandelayo kumazinga okushisa angu-900-1150°F ihora elilodwa kuya kwamane imvula iqinisa ingxubevange.Lokhu kwelashwa okuqinisa futhi kuthulisa isakhiwo se-martensitic, okwandisa i-ductility kanye nokuqina.

Kungani 17-4PH ?
•Kulula ukulungisa izinga lamandla, okungukuthi ngezinguquko zenqubo yokwelapha ukushisa ukuze kulungisweukuguqulwa kwesigaba se-martensite nokuguga
ukwelashwa kwensimbi eyenza imvula iqine isigaba.
•Ukumelana nokukhathala kokugqwala nokumelana namanzi.
•Ukushisela:Esimeni sesixazululo esiqinile, ukuguga noma ukuguga ngokweqile, ingxubevange ingashiselwa ngendlela eqinile, ngaphandle kokushisa kuqala.
Uma ufuna amandla okushisela eduze namandla ensimbi okuguga aqiniswe, khona-ke ingxubevange kufanele ibe yisixazululo esiqinile kanye nokwelashwa kokuguga ngemuva kokushisela.
Le alloy ibuye ifanele ukubhula, futhi izinga lokushisa elingcono kakhulu le-brazing yizinga lokushisa lesixazululo.
•Ukumelana nokugqwala:Ukumelana nokugqwala kwe-alloy kuphakeme kunanoma iyiphi enye insimbi engagqwali eqinile eqinile, emanzini angashintshi ahlushwa ukugqwala noma imifantu.Embonini yamakhemikhali e-petroleum, ukucubungula ukudla kanye nemboni yephepha enokumelana nokugqwala okuhle.
17-4PH Inkambu yohlelo lokusebenza:
•Amapulatifomu angasogwini, indawo yendiza enophephela emhlane, amanye amapulatifomu.
•Imboni yokudla.
•Imboni ye-Pulp nephepha.
•Isikhala (i-turbine blade).
•Izingxenye zemishini.
•Imiphongolo yemfucuza yenuzi.
