HK40 ni - ikoreshwa cyane - karubone 25Cr - 20Ni ubushyuhe bwa austenitike - irwanya ibishishwa bya ASTM A297. Bitewe na karubone iringaniye, chromium na nikel, ibi bikoresho bitanga imbaraga zidasanzwe zo hejuru yubushyuhe - imbaraga zo guturika, imbaraga za okiside iruta imbaraga hamwe n’imikorere myiza yo kurwanya car carburizing mu gihe kirekire - serivisi y’ubushyuhe.

Ibikoresho bya mashini (Igisubizo condition imiterere ivurwa)
Imbaraga zingana Rm: Birarenze cyangwa bingana na 425 MPa
Gutanga imbaraga Rp0.2: Birarenze cyangwa bingana na MPa 240
Kurambura A: Birarenze cyangwa bingana na 10%
Ubushyuhe bwo gukora
Ubushyuhe bukomeza gukora: dogere 950 degree1100 dogere
Ubushyuhe bugufi - igihe cy'ubushyuhe: kugeza kuri dogere 1150‑1200
Ibyiza byibicuruzwa
Ubwiza buhebuje - ubushyuhe bwikurikiranya, kurwanya ihindagurika munsi yubushyuhe bukabije
Ibyiza byo hejuru - ubushyuhe bwa okiside irwanya, kurwanya - igipimo cyo gukuramo
Imikorere yizewe anti - carburizing kumikorere yubushyuhe - kuvura hamwe nitanura rya peteroli
Ubushyuhe bwiza - cycle umunaniro urwanya ubushyuhe bwinshi - gukonjesha akazi
Umuti annealing kuvura kugirango ukureho ibibazo byimbere, hindura microstructure
📌 Ibice bisanzwe bya HK40
Itanura rya feri bar / ibice byo gutanura
Isahani yumuriro, itanura, ubushyuhe - irwanya kwihanganira
Ubushyuhe - kuvura itanura ibitebo, tray, ibikoresho, inkunga
Imiyoboro yumucyo, imiyoboro ivugurura inganda za peteroli
Ibikoresho byo gutwika, imashini yangiza
Ubushobozi bwacu bwo gukora
Dutanga umusaruro wa HK40 dukoresheje umusenyi, gutakaza - guta ifuro, guta ishoramari no guterana.
Gukemura ubushyuhe bukabije kuri dogere 1150‑1200 bikorwa kuri buri cyiciro.
Dushyigikiye umusaruro wa OEM & ODM ukurikije ibishushanyo byawe cyangwa ingero.
