Ngā Mea Katoa mō te 4130 Steel (Ngā Āhuatanga, te Kaha, me ngā Whakamahinga)

Huānga	Ōrau (%)
Waro (C)	0.28 – 0.33
Konukōmiuma (Kr)	0.80 – 1.10
Molibdenuma (Mo)	0.15 – 0.25
Manganēhi (Mn)	0.40 – 0.60
Hiraka (Si)	0.15 – 0.35
Whānariki (S)	≤ 0.040
Whēkau (P)	≤ 0.035

Ka whakanui ake te chromium i te pakeke, te kaha kume, me te ātete ki te waikura, ko te molybdenum ia ka whakapai ake i te pakari, te ātete ki te ngoki, me te pakeketanga.

Ngā Āhuatanga Hangarau o te Rino 4130

He rerekē ngā āhuatanga ā-pūkaha o te maitai 4130 i runga i te āhua o tōna maimoatanga wera. Ko ngā uara noa mō ngā āhua kua whakaritea, kua tineihia rānei, kua whakamahanatia ko:

• Kaha Kume: 560 – 1080 MPa

• Te Kaha o te Hua: 460 – 930 MPa

• Te Toronga i te Wā Whakamutu: 18 – 25%

• Te pakeketanga: 149 – 217 HB (Brinell), kei runga i te āhua

• Kiato7.85 karamu/cm³

• Te Tauwehenga o te Āhuatanga~205 GPa

Nā ēnei uara ka pai te maitai 4130 mō ngā tono ahotea teitei e hiahiatia ana he taurite o te kaha me te ngāwari.

Te Whakamahana i te Rino 4130

He pai te urupare a te maitai 4130 ki ngā tukanga maimoatanga wera maha, e āhei ai ngā kaihangarau ki te whakatikatika i ōna āhuatanga.

1. Te whakamahana– Te whakamahana ki te 870°C (1600°F) me te whakamatao puhoi kia pai ake ai te mahi miihini.

2. Te Whakaōrite– Te whakamahana ki te 900°C (1650°F) ā, muri iho ka whakamataohia ki te hau hei whakapai ake i te hanganga o te witi.

3. Te Whakamātao me te Whakamātao– Te whakamahana ki te ~870°C, te tinei i te hinu, te wai rānei, kātahi ka whakamahana i waenga i te 400°C–700°C kia whiwhi ai i te māro me te pakari e hiahiatia ana.

4. Te Whakapakari i te Take– Te whakakāpūhau, te whakanitā rānei hei whakapakari i te mata, me te pupuri tonu i te uho kia pakari.

Te Kaha o te Rino 4130

Ko te kaha o te maitai 4130 e whakawhirinaki ana ki te maimoatanga wera. I roto i te āhua whakamahana, he kaha ngawari engari he kaha miihini teitei. I roto i te āhua tineia me te whakamahana, ka eke ki te kaha kume me te kaha tuku teitei ake, e pai ai mō ngā wāhanga hanganga i raro i te kawenga taumaha.

Hei tauira:

• Āhua WhakamahanaKaha Kume ~560 MPa, Kaha Tuku ~460 MPa

• Āhua kua tineihia, kua whakamahanahia hokiKaha Kume ~1080 MPa, Kaha Tuku ~930 MPa

Nā tēnei whānuitanga o ngā mahi ā-mīhini ka taea te whakamahi i te maitai 4130 puta noa i ngā ahumahi maha.

Ātete ki te Waikura

Ahakoa kei roto i te maitai 4130 te chromium, he iti ake tōna ātete ki te waikura i ngā maitai kore waikura. Mō ngā taiao e ngāwari ana ki te waikura, e taunakihia ana kia pania, kia whakakikoruatia, kia peitatia rānei. I roto i ngā mahi rererangi me ngā mahi motuka, he maha ngā wā ka peitahia, ka pania rānei ki te paura hei ārai i te waikura.

Te Āheinga Whakarewa me te Āheinga Mīhini

Ko tētahi o ngā painga matua o te maitai 4130 ko tōna ngāwari ki te whakarewa. Ka taea te whakarewa mā te whakamahi i ngā tikanga TIG, MIG, oxy-acetylene rānei, mena ka tika te whakamahana i mua (150°C–300°C) kia kore ai e pakaru. He maha ngā wā ka whakamahia te whakamama i te ahotea i muri i te whakarewa mō ngā wāhanga nui.

He pai te āheinga miihini ina kei roto te maitai i te āhua whakamahana. Tērā pea ka hiahiatia he taputapu karāhe me te tere puhoi ake mō te 4130 kua tukatukahia ki te wera.

Ngā Momo Noa o te 4130 Rino

He maha ngā āhua o te maitai 4130 hei whakatutuki i ngā tukanga hanga rerekē:

• Ngā pae porowhita

• Ngā ngongo me ngā paipa

• Ngā pepa me ngā pereti

• Ngā poraka hanga

• Waea

Ngā kaihanga e pai ana kisakysteelte tuku i ēnei puka ki ngā ahumahi o te ao katoa, kia rite ai te kounga me te tutuki i ngā paerewa ASTM.
