Zvimiro zveSimbi ye4130

Hunhu hwesimbi ye4130 hunosiyana zvichienderana nemamiriro ayo ekupisa. Zvakajairika zvemamiriro ezvinhu akajairwa kana akadzima uye akadziya ndeizvi:

• Simba reKusimba: 560 – 1080 MPa

• Simba reGoho: 460 – 930 MPa

• Kureba paKuzorora: 18 - 25%

• Kuoma: 149 – 217 HB (Brinell), zvichienderana nemamiriro ezvinhu

• Kuwanda kwevanhu: 7.85 g/cm³

• Modulus yeElasticity: ~205 GPa

Izvi zvinoita kuti simbi ye4130 ikwane kushandiswa pakusimba kwakanyanya uko kunodiwa kuenzana kwesimba uye ductility.

Kurapa Kupisa kweSimbi ye4130

Simbi ye4130 inopindura zvakanaka kune nzira dzakasiyana-siyana dzekurapa kupisa, zvichibvumira mainjiniya kugadzirisa hunhu hwayo.

1. Kunyungudutsa– Kupisa kusvika 870°C (1600°F) uye kutonhora zvishoma nezvishoma kuti michina ive nani.

2. Kugadzirisa zvinhu– Kupisa kusvika 900°C (1650°F) zvichiteverwa nekutonhodza kwemhepo kuti zvigadziko zvegorosi zvinyatsonaka.

3. Kudzima uye Kugadzirisa– Kudziisa kusvika ~870°C, kudzima mafuta kana mvura, wozodziisa pakati pe400°C–700°C kuti uwane kuomarara uye kusimba kwaunoda.

4. Kuomesa Nyaya– Kuisa kabhoni kana kuti nitriding kuti pave nekuomarara kwepamusoro ukuwo mukati mayo muchiramba makasimba.

Simba reSimbi ye4130

Simba resimbi ye4130 rinoenderana nekupisa kwairi kuita. Kana yaiswa muchimiro che annealed, ine simba riri pakati nepakati asi ine simba rekugadzira rakawanda. Kana yadzimwa uye yakadzikira, ine simba rakawanda rekudhonza uye rinoburitsa simba rayo, zvichiita kuti ive yakakodzera zvikamu zvechivakwa zviri muchimiro chayo.

Semuyenzaniso:

• Mamiriro AkavharirwaSimba reKubata ~560 MPa, Simba reKuburitsa ~460 MPa

• Mamiriro Akadzima & AkadzikamaSimba reKubata ~1080 MPa, Simba reKuburitsa ~930 MPa

Kushanda kwesimbi uku kunoita kuti simbi ye4130 ishandiswe zvakasiyana-siyana mumaindasitiri akasiyana-siyana.

Kuramba Kuora

Kunyange zvazvo simbi ye4130 iine chromium, kuramba kwayo ngura kwakaderera pane simbi dzisina ngura. Kune nzvimbo dzinogara dzichiita ngura, machira ekudzivirira, mapurasitiki, kana kupenda zvinokurudzirwa. Mukushandiswa kwemuchadenga nemotokari, inowanzo pendwa kana kuputirwa nehupfu kudzivirira oxidation.

Kuchinjika uye Kugona Kuchinjika

Chimwe chezvakanakira zvikuru zvesimbi ye4130 ndechekuti inogona kusungirirwa zvakanaka. Inogona kusungirirwa uchishandisa nzira dzeTIG, MIG, kana oxy-acetylene, chero bedzi kudziyisa kwakakodzera (150°C–300°C) kwakaitwa kudzivirira kutsemuka. Kurerutsira kushushikana mushure mekusungirirwa kunowanzo shandiswa pazvinhu zvakakosha.

Kugona kugadzika kunoonekwa sekwakanaka kana simbi iri mumamiriro ekubatidzwa. 4130 inogadziriswa nekupisa ingada maturusi ecarbide uye kumhanya kunononoka.

Mafomu Akajairika eSimbi ye4130

Simbi ye4130 inowanikwa mumhando dzakasiyana-siyana kuti ikwane maitiro akasiyana ekugadzira:

• Mabhawa akatenderera

• Machubhu nemapombi

• Mapepa nemaplate

• Zvidhinha zvakagadzirwa

• Waya

Vagadziri vakaita sesakysteelkupa mafomu aya kumaindasitiri pasi rese, zvichiva nechokwadi chekuti mhando yacho inogara iripo uye kuti mitemo yeASTM inoenderana.
