Saina UNS T30407 ASTM A681 faia galuega malulu D7 Meafaigaluega pa uamea Gaosi ma Fa'atau | Ruiyi
u'amea pa'u pa'u vevela D7o se u'amea u'amea masani fa'aaogaina, ma o ona vaega autu o le carbon (C), chromium (Cr), molybdenum (Mo), manganese (Mn) ma le silicon (Si). O lona tuufaatasiga kemikolo ma mea tau masini e faapea:
vaila'au fa'apitoa:
– Kaponi (C): 1.40-1.60%
– Chromium (Cr): 11.00-13.00%
– Molybdenum (Mo): 0.50-1.10%
– Manganese (Mn): 0.20-0.60%
– Silisi (Si): 0.10-0.40%
Amioga fa'ainisinia:
- Malosi faʻamalosi: ≥1275 MPa
- Malosi e maua ai: ≥1120 MPa
- Fa'aumiumi: ≥15%
– Malosi: ≥321 HB
Hot forging die steel D7 e maualuga le maaa, maualuga le malosi, lelei le ofuina ma le faʻamautuina o le vevela, ma e talafeagai mo le gaosiga o masini, faʻamaufaʻailogaina, meafaigaluega tipi ma isi meafaigaluega ma vaega e manaʻomia ai le malosi maualuga ma le ofuina o le teteʻe.
| Ituaiga oloa | Oloa | Fua | Fa'agasologa | Tuuina atu Tulaga |

D7 mate uʻamea o se uʻamea mea faigaluega malulu maualuga-carbon maualuga-chromium ma lelei le ofuina teteʻe, maaa ma vevela tetee, ma e talafeagai mo le gaosiga eseese ma meafaigaluega. O nisi nei o fa'aoga autu ole D7 meafaigaluega uamea:
1. Fa'ailoga fa'ailoga ua mate: O le u'amea D7 e maualuga lona ma'a'a ma le ofuina, ma e talafeagai mo le gaosiga o fa'ailoga fa'ailoga, e pei o tu'i ma nofoa tu'i.
2. Gaosi mea faigaluega tipi: O le maaa ma le ofuina o le D7 mold sila e avea ma mea lelei mo le gaosiga o meafaigaluega tipi, e pei o naifi, vili vili, vili, ma isi.
3. Fausia galuega malulu mate: D7 mate uamea e sili ona lelei le ofuina ma teteʻe aʻafiaga, ma e talafeagai mo le gaosiga malulu galuega mate, e pei o blanking mate, punou mate, ma isi.
4. Fausiaina o galuega vevela mate: D7 mate uʻamea e maualuga le vevela ma e talafeagai mo le gaosiga o galuega vevela, e pei o le vevela vevela mate, vevela vevela mate, ma isi.
5. Fausiaina o palasitika palasitika: D7 mold sila e lelei le ofuina o le ofuina ma le corrosion resistance, ma e talafeagai mo le faia o palasitika palasitika, e pei o tui tui, extrusion molds, ma isi.
Ona o lona maaa sili ona lelei, ofuina le teteʻe ma le vevela, D7 mate uamea e masani ona faʻaaogaina i le fale gaosi oloa e gaosia ai ituaiga eseese o oti ma meafaigaluega e faʻaleleia ai le gaosiga lelei ma le lelei o oloa.
E mafai e RAYIWELL ona ofoina atu isi galuega vevela po'o le mea faigaluega malulu uamea mafolafola pa po'o le lapotopoto pa e pei ona taua i lalo, matou te fa'afeiloa'i fo'i le fa'atonuga fa'ale-aganu'u.
