I-AISI 4140 Steel 1.7225 42CrMo4 SCM440

I-AISI 4140 Alloy Steel insimbi evamile ye-chromium-molybdenum evamise ukusetshenziswa ngemva kokucinywa nokufutheka, ngamandla amakhulu, ukuqina okuphezulu. Ipuleti le-alloy 4140 liphinde libe namandla aphezulu okukhathala kanye nokuqina okuhle komthelela wezinga lokushisa eliphansi.

I-Gnee inenzuzo enkulu ku-4140 steel plate:

• 1500+ amathani isitoko sansuku zonke se-4140 alloy plate noma ibha eyisicaba.
• Isimo / esigoqiwe esishisayo / Q+T (PH esiqinile ngaphambili) siyatholakala.
• Ubukhulu 4-300mm buyatholakala ukuthunyelwa kwezinsuku ezingu-1-3.
• Ukuqina 1-10mm ishidi eligoqiwe elibandayo izinsuku ezingama-30 zokuhola.
• Isevisi ye-Sika ibe ububanzi futhi usike ube nobude obutholakalayo.
• Isevisi yomshini wokubekezelela kanye nensizakalo ye-roughness iyatholakala.

Uma kuxoxwa nge-AISI 4140, kubalulekile ukuqonda ukuthi inombolo yebanga isho ukuthini:

I-AISI 4140 yenziwa ngokubeka insimbi, ikhabhoni, nezinye izakhi eziwuketshezi esithandweni somlilo sikagesi noma esithandweni somoya-mpilo. Izakhi ezinkulu ze-alloying ezengezwe ku-AISI 4140 yilezi:

• I-Chromium
• IManganese
• I-Molybdenum

Uma i-iron, i-carbon, nezinye izakhi ze-alloying sezixubene ndawonye zibe uketshezi, kuvunyelwe ukupholisa. Insimbi ingase idonswe; mhlawumbe izikhathi eziningana.

Ngemva kokuqedwa kokufakwa kwe-annealing, insimbi iyashisisa ibe yisigaba esincibilikisiwe futhi ukuze ikwazi ukuthelwa efomini oyifunayo futhi ingase isetshenziswe ishise noma igodole ngamarola noma amanye amathuluzi ukuze ifinyelele ubukhulu obufunekayo. Yebo, kukhona okunye ukusebenza okukhethekile okungangezwa kulokhu ukunciphisa isikali sokugaya noma ukuthuthukisa izakhiwo zemishini.

I-AISI 4140 iyinsimbi ephansi ye-alloy. Izinsimbi ze-alloy eziphansi zincike ezintweni ngaphandle nje kwe-iron ne-carbon ukuze kuthuthukiswe izakhiwo zazo zemishini. Ku-AISI 4140, izengezo ze-chromium, i-molybdenum, ne-manganese zisetshenziselwa ukukhulisa amandla kanye nokuqina kwensimbi. Ukwengezwa kwe-chromium ne-molybdenum yingakho i-AISI 4140 ibhekwa njengensimbi "ye-chromoly".

Kunezindawo ezimbalwa ezibalulekile zemishini ye-AISI 4140, kufaka phakathi:

• Amandla Okuqina: Insimbi ye-AISI 4140 ivamise ukuba namandla aqinile aqinile acishe abe ngu-95,000 psi.
• Ukuqina
• I-Ductility
• Ukuqina

Ithebula elingezansi ligqamisa ukwakheka kwamakhemikhali kwe-AISI 4140:

Ukwengezwa kwe-chromium ne-molybdenum kukhuthaza ukumelana nokugqwala. I-molybdenum ingaba usizo ikakhulukazi lapho uzama ukumelana nokugqwala ngenxa yama-chloride. I-manganese eku-AISI 4140 isetshenziselwa ukukhulisa ukuqina kanye ne-deoxidizer. Ezinsimbi ze-alloy, i-manganese ingabuye ihlangane nesibabule ukuze kuthuthukiswe ukusebenza kahle futhi yenze inqubo yokungcwatshwa kwe-carburizing iphumelele kakhulu.
