Konke Malunga ne-4130 Steel (Iipropati, Amandla, kunye nokusetyenziswa)

I-elementi	Ipesenti (%)
Ikhabhoni (C)	0.28 – 0.33
I-Chromium (Cr)	0.80 – 1.10
I-Molybdenum (Mo)	0.15 – 0.25
IManganese (Mn)	0.40 – 0.60
I-Silicon (Si)	0.15 – 0.35
I-Sulfur (S)	≤ 0.040
I-Phosphorus (P)	≤ 0.035

I-Chromium yonyusa ubulukhuni, amandla okutsalwa, kunye nokumelana nokugqwala, ngelixa i-molybdenum iphucula ubulukhuni, ukumelana nokurhubuluza, kunye nokuqina.

Iipropati zoomatshini zentsimbi ye-4130

Iimpawu zoomatshini zentsimbi ye-4130 ziyahluka ngokuxhomekeke kwimeko yayo yonyango lobushushu. Amaxabiso aqhelekileyo kwiimeko eziqhelekileyo okanye ezicinyiweyo neziqinisiweyo zezi:

• Tensile strength: 560 – 1080 MPa

• Unikeze Amandla: 460 – 930 MPa

• Ukwandiswa ngexesha lokuphumla: 18 – 25%

• Ukuqina: 149 – 217 HB (Brinell), kuxhomekeke kwimeko

• Uxinano: 7.85 g/cm³

• Imodulus ye-Elasticity: ~205 GPa

Ezi xabiso zenza intsimbi engama-4130 ifaneleke ukusetyenziswa ngoxinzelelo oluphezulu apho kufuneka ulungelelwano lwamandla kunye nokuguquguquka.

Unyango lobushushu lwentsimbi ye-4130

Intsimbi ye-4130 isabela kakuhle kwiinkqubo ezahlukeneyo zonyango lobushushu, ivumela iinjineli ukuba zilungise iimpawu zayo.

1. Ukuqokelela– Ukufudumeza ukuya kuthi ga kwi-870°C (1600°F) kunye nokuphola kancinci ukuze kuphuculwe ukusebenza komatshini.

2. Ukulungisa izinto zibe zesiqhelo– Ukufudumeza ukuya kuthi ga kwi-900°C (1650°F) kulandele ukupholisa ngomoya ukuze kucocwe isakhiwo sengqolowa.

3. Ukucima kunye nokunciphisa– Ukufudumeza ukuya kuthi ga kwi-870°C, ukucima ioyile okanye amanzi, uze emva koko ufudumeze phakathi kwe-400°C–700°C ukuze ufumane ubunzima nokuqina okufunekayo.

4. Ukuqinisa iTyala– Ukugalela i-carburizing okanye i-nitriding ukuze kubekho ubulukhuni obungakumbi bomphezulu ngelixa ugcina umbindi uqinile.

Amandla entsimbi ye-4130

Amandla entsimbi ye-4130 axhomekeke kunyango lobushushu. Kwimeko efakwe intsimbi, inika amandla aphakathi kodwa inamandla aphezulu okusebenza. Kwimeko ecinyiweyo nethomalalisiweyo, ifikelela kumandla aphezulu okutsalwa kunye nokukhupha, okwenza ifaneleke kwiindawo zokwakha phantsi komthwalo onzima.

Umzekelo:

• Imeko eNgxotshiweyo: Amandla okuThamba ~560 MPa, Amandla okuKhula ~460 MPa

• Imeko Ecinyiweyo Neyomeleleyo: Amandla okuThamba ~1080 MPa, Amandla okuKhula ~930 MPa

Olu luhlu lokusebenza koomatshini lwenza intsimbi ye-4130 ibe nobuchule kwiindawo ezahlukeneyo.

Ukumelana nokugqwala

Nangona intsimbi ye-4130 ine-chromium, ukumelana kwayo nokugqwala kuphantsi kunentsimbi engagqwaliyo. Kwiindawo ezithandwa kukugqwala, kucetyiswa ukuba kufakwe ii-coating zokukhusela, ii-plating, okanye iipeyinti. Kwizicelo zeenqwelo-moya nakwiimoto, idla ngokupeyintwa okanye ifakwe i-powder-coating ukuthintela i-oxidation.

Ukudityaniswa kunye nokuSebenza

Enye yeenzuzo eziphambili zentsimbi ye-4130 kukukwazi kwayo ukuwelda kakuhle. Ingawelda kusetyenziswa iindlela ze-TIG, MIG, okanye i-oxy-acetylene, ukuba nje ifudunyezwa ngokufanelekileyo (150°C–300°C) ukuze kuthintelwe ukuqhekeka. Ukunciphisa uxinzelelo emva kokuwelda kudla ngokusetyenziswa kwiindawo ezibalulekileyo.

Ukukwazi ukusebenza ngomatshini kuthathwa njengokulungileyo xa intsimbi ikwimeko yokutsalwa. I-4130 enyangwa ngobushushu ingafuna izixhobo zekhabhayithi kunye nesantya esicothayo.
