SAE4340 40CrNiMoA Umuyoboro utagira ibyuma

SAE4340 40CrNiMoA Alloy Ikidodo Cyuma Cyuma Cyerekanwe

Ibisobanuro bigufi:

40CrNiMoA alloy idafite icyuma ni umuyoboro mwinshi, ukomeye-ukomeye cyane wavanze ibyuma byubatswe.Ibigize birimo ahanini chromium, nikel, molybdenum hamwe na karuboni nkeya, silikoni, manganese nibindi bintu, binyuze mubipimo byihariye hamwe no gutunganya ubushyuhe, bifite imbaraga zo kurwanya ruswa no gukora ubushyuhe bwinshi.Bitewe nuburyo bwiza bwubukanishi hamwe nuburyo bugari bwo gukoresha, bwakoreshejwe cyane mu nganda nyinshi.

Umwanya wo gusaba

1. Mu nganda zikomoka kuri peteroli, irashobora gukoreshwa mugukora ibikoresho byingenzi nkibikoresho byumuvuduko ukabije, reaction, guhinduranya ubushyuhe, nibindi, bishobora kwihanganira ingaruka zubushyuhe bwinshi, umuvuduko mwinshi nibitangazamakuru byangiza.

2. Mu nganda zikoresha amashanyarazi, irashobora gukoreshwa mugukora ibice byamashanyarazi, amashyiga, amashyanyarazi hamwe nibindi bikoresho, bishobora kwihanganira umutwaro mwinshi hamwe nubushyuhe bwo hejuru.

3. Mu kirere cyo mu kirere, irashobora gukoreshwa mu gukora ibice by'ingenzi nk'ibikoresho bigwa mu ndege hamwe n'ibikoresho bya fuselage mu rwego rwo kuzamura umutekano n'imikorere y'indege.

Byongeye kandi, imiyoboro ya 40CrNiMoA irashobora kandi gukoreshwa mugukora ibice byingenzi mumamodoka, amato, gari ya moshi nizindi nganda kugirango ubuziranenge bwibicuruzwa kandi byizewe.

Ibisobanuro byo kuvura ubushyuhe

Kuzimya ubushyuhe: 850 ºC;gukonjesha: amavuta;ubushyuhe bukabije: 600 ºC;gukonjesha: amazi, amavuta.

Imiterere yo Gutanga

Gutanga mu kuvura ubushyuhe (bisanzwe, annealing cyangwa ubushyuhe bwo hejuru) cyangwa nta buryo bwo kuvura ubushyuhe, imiterere yo kubyara igomba kugaragazwa mumasezerano.
