TheASTM A312 UNS S30815 253MA Stainless Steel Pipendeyepamusoro-inoshanda austenitic Stainless simbi alloy inozivikanwa nekupikisa kwayo kwepamusoro-tembiricha oxidation, ngura, uye yakanakisa michina zvivakwa munzvimbo dzakakwirira dzetembiricha.253MAyakagadzirirwa zvakananga kushumirwa mumashandisirwo anoda kugadzikana kwepamusoro-tembiricha, kunyanya muchoto uye kupisa kupisa maindasitiri. Kupokana kwayo kwakatanhamara kuyera, carburization, uye general oxidation inoita kuti ive chinhu chakavimbika kune yakanyanyisa nharaunda.
Iri giredhi resimbi isina tsvina rinoshandiswa zvakanyanya mukupisa-tembiricha maindasitiri uye rakanakira maapplication uko ese ari maviri epamusoro simba uye oxidation kuramba kwakakosha.
Zviyero uye Zvinotsanangurwa
TheASTM A312 UNS S30815 253MA Stainless Steel Pipeinogadzirwa maererano nemitemo inotevera:
- ASTM A312: Yakajairwa Kutsanangurwa kweSeamless, Welded, uye Yakanyanya Kutonhora Yakashanda Austenitic Stainless Steel Pipes
- UNS S30815: The Unified Numbering System for Materials inoratidza izvi segiredhi resimbi isina tsvina.
- EN 10088-2: European Standard yeStainless Simbi, inovhara zvinodiwa pakuumbwa kwechinhu ichi, michina zvivakwa, uye kuyedzwa.
Kuumbwa Kwemakemikari(% neHuremu)
Mushonga wemakemikari we253MA (UNS S30815)yakagadzirirwa kupa yakanakisa kuramba kune oxidation uye yakakwirira-tembiricha simba. Iyo yakajairwa kuumbwa ndeyekutevera:
| Element | Kuumbwa (%) |
| Chromium (Cr) | 20.00 - 23.00% |
| Nickel (Ni) | 24.00 - 26.00% |
| Silicon (Si) | 1.50 - 2.50% |
| Manganese (Mn) | 1.00 - 2.00% |
| Kabhoni (C) | ≤ 0.08% |
| Phosphorus (P) | ≤ 0.045% |
| Sarufa (S) | ≤ 0.030% |
| Nitrogen (N) | 0.10 - 0.30% |
| Simbi (Fe) | Balance |
Zvinhu Zvekushandisa: Hunhu Hunokosha
253MA(UNS S30815) inosanganisa yakanakisa yepamusoro-tembiricha simba neoxidation kuramba. Izvi zvinoita kuti ive yakanaka kune maapplication ari munzvimbo dzakanyanyisa, senge mavira uye kupisa exchanger. Izvo zvinhu zvine yakakwira chromium uye nickel yemukati, inopa yakanakisa kuramba oxidation patembiricha inosvika 1150 ° C (2100 ° F).

Kugadzira Maitiro: Hunyanzvi hwePrecision
Kugadzirwa kwe253MA Stainless Simbi Mapaipiinotevera nzira dzemazuva ano dzekugadzira kuti ive nechokwadi chemhando yepamusoro uye kusimba:
- Seamless Pipe Manufacturing: Yakagadzirwa kuburikidza ne extrusion, kuboora kutenderera, uye elongation maitiro ekugadzira mapombi asina musono ane yunifomu yemadziro ukobvu.
- Kutonhora-Kushanda Maitiro: Inotonhora kudhirowa kana pilgering maitiro anoshandiswa kuti azadzise zviyero uye nzvimbo dzakatsetseka.
- Kupisa Kurapa: Mapombi anorapwa kupisa pane chaiwo tembiricha kuti awedzere ma mechanic zvivakwa uye yakakwirira-tembiricha kuita.
- Pickling & Passivation: Mapombi anopinzwa kuti abvise zviyero uye oxide mafirimu uye anopfuudzwa kuti ave nechokwadi chekuramba kuenderera mberi nekuora.
Kuedza uye Kuongorora: Kuvimbiswa Kwehutano
Womic Steel inoteedzera yakaomesesa yekuyedza protocol kuti ive yemhando yepamusoro ye253MA Stainless Simbi Mapaipi:
- Chemical Composition Analysis: Yakasimbiswa uchishandisa spectroscopic matekiniki kuratidza kuti alloy inosangana neakadururwa nziyo.
- Mechanical Testing: Tensile, kuoma, uye kukanganisa kuyedzwa kuti uone kushanda kwezvinhu patembiricha dzakasiyana.
- Hydrostatic Testing: Mapombi anoedzwa kusimba kusimba kuti ave nechokwadi chekuvuza-isina kuita.
- Kuyedzwa Kusina Kuparadza (NDT): Inosanganisira ultrasonic, eddy ikozvino, uye dhayi inopinda mukati mekuyedza kuona chero mukati kana pamusoro pehurema.
- Visual & Dimensional Inspection: Imwe neimwe pombi inotariswa nemaziso kuti ipere, uye kurongeka kwedimensional kunotariswa maererano nezvakatsanangurwa.
