AISI 4140 Icyuma 1.7225 42CrMo4 SCM440

AISI 4140 Alloy Steel nicyuma gisanzwe cya chromium-molybdenum isanzwe ikoreshwa nyuma yo kuzimya no gutwarwa, hamwe nimbaraga nyinshi, gukomera cyane. Isahani ya alloy 4140 nayo ifite imbaraga zumunaniro mwinshi hamwe nubushyuhe buke bwo hasi.

Gnee ifite inyungu nini kuri plaque 4140:

• Toni 1500+ buri munsi ububiko bwa 4140 isahani cyangwa isahani iringaniye.
• Bishyushye / bifatanye / Q + T (PH yabanjirije) imiterere irahari.
• Umubyimba 4-300mm uraboneka muminsi 1-3 yoherejwe.
• Umubyimba 1-10mm urupapuro rukonje ruzengurutse iminsi 30 yo kuyobora.
• Kata mubugari & gukata kumurongo muremure urahari.
• Imashini yo kwihanganira & roughness ibice serivisi irahari.

Mugihe muganira kuri AISI 4140, ni ngombwa kumva icyo umubare wamanota usobanura:

AISI 4140 ikorwa mugushira ibyuma, karubone, nibindi bintu bivanga mu itanura ryamashanyarazi cyangwa itanura rya ogisijeni. Ibintu byingenzi bivangavanze byongewe kuri AISI 4140 ni:

• Chromium
• Manganese
• Molybdenum

Iyo ibyuma, karubone, nibindi bintu bivanga bimaze kuvangwa hamwe muburyo bwamazi, biremewe gukonja. Ibyuma birashobora noneho gufatanwa; birashoboka inshuro nyinshi.

Annealing imaze kurangira, ibyuma byongeye gushyukwa mugice cyashongeshejwe kugirango gishobore gusukwa muburyo bwifuzwa kandi gishobora kuba gishyushye cyangwa ubukonje bukorwa binyuze mumuzingo cyangwa ibindi bikoresho kugirango bigere kubyimbye. Byumvikane ko, hari nibindi bikorwa byihariye bishobora kongerwaho kuriyi kugirango bigabanye urusyo cyangwa kunoza imiterere yubukanishi.

AISI 4140 nicyuma gike cyane. Icyuma gike cyane gishingiye kubintu bitari ibyuma na karubone gusa kugirango byongere imiterere yabyo. Muri AISI 4140, hiyongeraho chromium, molybdenum, na manganese bikoreshwa mu kongera imbaraga no gukomera kwicyuma. Kwiyongera kwa chromium na molybdenum niyo mpamvu AISI 4140 ifatwa nkicyuma cya "chromoly".

Hariho ibintu byinshi byingenzi byubukanishi bwa AISI 4140, harimo:

• Imbaraga za Tensile: AISI 4140 ibyuma mubisanzwe bifite intego ntarengwa ya tensile yingana na 95.000 psi.
• Gukomera
• Guhindagurika
• Gukomera

Imbonerahamwe ikurikira irerekana imiti ya AISI 4140:

Kwiyongera kwa chromium na molybdenum bitera kurwanya ruswa. Molybdenum irashobora kuba ingirakamaro cyane mugihe ugerageza kurwanya ruswa bitewe na chloride. Manganese muri AISI 4140 ikoreshwa mukwongera ubukana kandi nka deoxidizer. Mu byuma bivangavanze, manganese irashobora kandi guhuza na sulfure kugirango irusheho gukora neza kandi itume carburizing ikora neza.
