1. Hunhu hwezvinhu uye zvakajairwa
34CrMo4 isimbi yakagadzirwa ne chromium-molybdenum alloy, iyo inowanzoshandiswa kugadzira masirinda egasi ane simba guru, masirinda nezvimwe zvikamu zvine zvinodiwa zvakasimba zvekushanda. Kubva pamaonero ezvakajairwa, ndeimwe yezvinhu zvesimbi zvakagadzirwa ne alloy zvakataurwa zvakajeka muEuropean standard EN 10083-3, uye inosanganawo nezvinodiwa zveChinese standard GB 18248, iyo pasina mubvunzo inopa vimbiso yakavimbika yehunhu hwayo nekushanda kwayo. Ine simba rakawanda, inodzivirira kupisa zvakanyanya uye inodzivirira kuneta. Mitemo yekushandisa 34CrMo4 seamless steel pipes yemasirinda egasi yakasiyana-siyana, ichifukidza mitemo yakawanda yenyika neyepasi rose. Izvi zvinosanganisira
Standard yechiChinese: GB/T 18248-2021 (yemachubhu egesi silinda chete)
Muyero weEuropean: EN 10083-3/EN 10297-1
Muyero wepasi rose: ISO 11120
Chiyero cheAmerica: ASTM A372/A372M-3
Chiyero cheJapan: JIS G 3429
2. Kudzora kuumbwa kwemakemikari (%)

Chinhu	C	Si	Mn	P≤	S≤	Cr	Mo	zvimwe
Zviri Mukati	0.30-0.37%	≤0.40%	0.60-0.90%	0.020%	0.020%	0.90-1.20%	0.15-0.30%	Ni≤0.30% Cu≤0.20%

Cherechedza: Fosforasi nesarufa zvese ≤ 0.030%

3.Kushanda kwakanaka kwazvo kwemakanika

Mushure mekupisa uye kudziya (kudzima + kudzimisa), pombi yesimbi isina musono ye34CrMo4 ine simba rekudhonza re ≥980MPa, simba rekuwedzera re ≥835MPa, uye kureba kwe ≥12%. Patembiricha yakaderera ye -50°, simba rekupinza rinogona kuramba riri ≥27J.

4. Pfungwa huru dzekugadzira
1. Maitiro ekugadzira:
Kushandisa nzira yekudhirowa inopisa inotenderedza/inotonhora isina musono → kuona zvikanganiso zve ultrasonic (UT) → kudzima nekudzikamisa (kudzima + kudzimisa) → bvunzo ye hydraulic → kuongorora chigadzirwa kwapera
2. Mamiriro ekutumira:
Kazhinji inotumirwa yakamonerwa kana kutorwa ichitonhora, kurapwa kwekupedzisira kwekupisa kunodiwa mushure mekunge mushandisi wekupedzisira agadzirisa.
5. Kunyorerana pakati pemamakisi epamba
34CrMo4 inoramba iine zita rimwe chete mumitemo yeChinese, uye mashandiro ayo akaenzana ne:
GB/T 3077: 34CrMo
Magiredhi akafanana: 42CrMo (chigadzirwa chinofanira kugadziriswa)
6. Nzvimbo dzakajairika dzekushandisa

Maindasitiri	Kushandiswa kwakananga	Zvinodiwa pakushanda
Kuchengetedza simba uye kutakurwa	Masilinda eCNG/LPG, masilinda ekuchengetera hydrogen	Kutakura kumanikidzwa kwakanyanya (20-35MPa)
Midziyo yekurapa	Masilinda eokisijeni yekurapa	Kuchena kwakanyanya (kune S/P shoma)
Midziyo yekudzimisa moto	Masilinda ekufema, masilinda ekudzimisa moto	Kusimba kwekupisa kwakaderera
Kutakurwa	Masilinda ehurongwa hwemabhureki emotokari dzekutengeserana	Kuneta kunodzivirira kudedera
Masoja nendege	Matangi epropellant	Kugadziriswa kwezviyo zvakatsetseka zvakanyanya

7. Magadzirirwo echigadzirwa chakajairika (mm)

Dhayamita yekunze: Φ108-356
Ukobvu hwemadziro: 4-16.8
Saizi dzakajairika:
Φ139.7×4.5, Φ203×5.4, Φ279×6.8, Φ355.6×7.5, nezvimwewo.
(Kugadzirisa saizi isiri yakajairika kunotsigirwa)
8. Nzvimbo huru dzekushandisa dze34CrMo4
34CrMo4, sechigadzirwa chesimbi chechromium-molybdenum, inonyanya kushandiswa kugadzira mapaipi esimbi asina musono emasilinda egasi ane simba guru/masilinda esimbi ane simba guru uye midziyo ine simba guru. Mukushanda kwayo, inonyanya kushandiswa mukugadzira masilinda eCNG, kusanganisira kugadzira masilinda egasi rechisikigo akamanikidzwa emotokari nemamwe masilinda emidziyo ane simba guru, zvichipa rutsigiro rwakavimbika rwezvinhu zveminda iyi.
