I-17-4PH iPhepha leDatha leMathiriyeli
Imida
I-stainless material 17-4 PH ibonakaliswe ngamandla okuvelisa isivuno, ukuchasana kakuhle kwe-corrosion kunye nokuxhatshazwa kokugqoka okuphezulu.I-17-4 PH yenye yezona zintsimbi ezibaluleke kakhulu ezinokuqiniswa.Kuyafana ngokuhlalutya kunye nezixhobo ze-1.4548 kunye ne-1.4542.
Ukusetyenziswa kwinqanaba eliphantsi lobushushu linokwenzeka nge-Condition H1150 kunye ne-H1025.Ukomelela kwempembelelo enophawu olugqwesileyo kukwanikezelwa kumaqondo obushushu obuncinci.
Ngenxa yeepropathi ezilungileyo zoomatshini kunye nokumelana nomhlwa, izinto ezisetyenziswayo zikulungele ukusetyenziswa kwindawo ezihlala elwandle, kodwa zisesichengeni sokonakala kwemingxuma kumanzi olwandle amileyo.
I-17-4PH yaziwa ngokuba yi-AISI 630.
Izinto eziphathekayo ze-17-4PH zisetyenziselwa imveliso yeekhemikhali, imboni yokhuni, icandelo le-offshore, ekwakheni iinqanawa, kubunjineli bemishini, kwishishini leoli, kumashishini ephepha, kwishishini lezemidlalo.Umzi-mveliso wokuzonwabisa kunye noguqulelo olunyibilikisiweyo kwakhona (ESU) emoyeni kunye ne-Aerospace.
Ukuba iipropathi zomatshini kunye nokuxhatshazwa kwe-corrosion of martensitic steels ayanelanga, i-17-4PH ingasetyenziswa.

Inzuzo
Enye ipropati ekhethekileyo yezinto eziphathekayo 17-4 PH kukufaneleka kwamaqondo okushisa aphantsi kunye nokusebenza ukuya kwi-approx.315°C.
Ukuqulunqa:Ukubunjwa kwezinto eziphathekayo kwenzeka kwiqondo lokushisa kwe-1180 ° C ukuya kwi-950 ° C. Ukuqinisekisa ukucocwa kweenkozo, ukupholisa kwiqondo lokushisa kwegumbi kwenziwa ngomoya.
Ukuwelda:Ngaphambi kokuba i-17-4 PH ifakwe kwizinto eziphathekayo, kufuneka kuqwalaselwe imeko yezinto ezisisiseko.Kwifom ezinzile, ubhedu lukhoyo kwizinto eziphathekayo.Oku kukhuthaza ukuqhekeka kushushu.
Ukuze ukwazi ukwenza i-welding iimeko zokuwelda zifunekayo.I-Undercuts okanye i-welding defects ingakhokelela ekubunjweni kwenotshi.Oko kufanele kuphetshwe.Ukuthintela ukwakheka kokuqhekeka koxinzelelo, izinto kufuneka ziphinde zixhomekeke kwisisombululo sokuguga kunye nokuguga okulandelayo ngexesha elifutshane kakhulu emva kwe-welding.
Ukuba akukho unyango emva kobushushu olwenzekayo, amaxabiso omatshini-tekhnoloji kwi-weld seam kunye nendawo echaphazeleke bubushushu kwizinto ezisisiseko inokwahluka kakhulu.
Ukuchasa umhlwa:xa iipropathi zomatshini kunye nokuxhatshazwa kwe-corrosion of martensitic steels ayanelanga, i-17-4 PH ifanelekile ukusetyenziswa kwiindawo zaselwandle.Inomdibaniso weempawu ezintle kakhulu zoomatshini kunye nokumelana nokubola.
Kumanzi olwandle amileyo, i-17-4 PH ichaphazeleka kukonakala kwimingxuma.Oku kufuna ukhuseleko olongezelelweyo.
Umatshini:I-17-4 PH inokutshintshwa kwimeko enzima kunye nesisombululo-efakwe kwisisombululo.Ngokuxhomekeke kubunzima, ukucwangciswa kwe-machina kuhluka, oku kuya kuxhomekeka kwimeko.
Unyango lobushushu
Phakathi kwe-1020 ° C kunye ne-1050 ° C izinto eziphathekayo 17-4 PH isisombululo-i-annealed.Oku kulandelwa kukupholisa ngokukhawuleza - amanzi, ioli okanye umoya.Oku kuxhomekeke kwi-cross-section yezinto eziphathekayo.
Ukuqinisekisa ukuguqulwa okupheleleyo ukusuka kwi-austenite ukuya kwi-martensite, izinto eziphathekayo kufuneka zibe namandla okupholisa phantsi kweqondo lokushisa.

Izinto eziluncedo kwisarha cut
Ukucutshungulwa nge-saw yi-mechanical processing of the material, ebangela ukuguqulwa okuncinci okungalindelekanga kunye nokwanda kobunzima besakhiwo esikhoyo, njengokusika kwe-thermal.
Ngaloo ndlela, i-workpiece yomatshini inesakhiwo esilinganayo nakwi-edge, engatshintshiyo ekuqhubekeni kwezinto.
Le meko ivumela ukugqiba ngokukhawuleza kwe-workpiece ngokusila okanye ukubhola.Ngoko akuyomfuneko ukuba anneal izinto okanye wenze umsebenzi ofanayo kwangaphambili.
