ASTM A536 Birta Lagu Tuuray Nodular | Usha Birta ee Shaadhka Shaadhka ah ee Spheridal Graphite
Hordhac Badeecada
ASTM A536 Nodular Cast Iron Bar waa walax si sax ah loo farsameeyay oo loogu talagalay codsiyada waxqabadka sare leh ee nidaamyada haydarooliga iyo baabuurta. Laga sameeyay heerka adag ee ASTM A536, birtan spheroidal graphite (SG) waxay isku daraysaa xoogga birta iyo sifooyinka birta ee ka-soo-saarka sare iyo gariirka. Waxaa si gaar ah loogu qiimeeyaa iska caabbinta daalka ee aadka u fiican, farsamaynta, iyo xasilloonida cabbirka ee cadaadiska.
Birta la shubay ee Nodular, oo sidoo kale loo yaqaan birta ductile, way ka duwan tahay birta cawlan iyadoo ka kooban kaarboonku ay sameeyaan qanjidhada graphite ee spheroidal halkii ay ka ahaan lahaayeen jajab. Kala soociddan qaab-dhismeedka ayaa siinaysa tamar aad u sarreysa iyo xoog wax soo saar, taasoo ka dhigaysa agab lagu kalsoonaan karo oo loogu talagalay deegaannada culayska qaada iyo cadaadiska sare leh.
- baararka birta ee ductile waxaa loo soo saaraa si waafaqsan heerarka caalamiga ah. Darajooyinka birta ee caadiga ah ee loo isticmaalo baararka birta ee ductile waxaa lagu muujiyaa siyaabo kala duwan iyadoo loo eegayo waddamada iyo heerarka kala duwan.
Kuwa soo socda waa heerarka birta ductile ee badanaa loo isticmaalo (darajooyinka) ee dhowr nidaam oo caadi ah:
| ASTM A536 | 1563kii | ISO 1083 | JIS G5502 |
| 60-40-18 | EN-GJS-400-15 | GGG40 | FCD400 |

| 100-70-03 | EN-GJS-600-3 | GGG60 | FCD600 |
Sharaxaadda Badeecada
Ulaha birta ah ee loo yaqaan "ductile iron" waxaa badanaa loo isticmaalaa meelaha sida geerka iyo qaybaha usha ee wax soo saarka farsamada, shaftyada crankshafts iyo ulaha isku xira warshadaha baabuurta, tuubooyinka iyo qaybaha dhismaha ee goobta dhismaha, qaybaha haydarooliga ee mashiinnada dhismaha, iyo waalka iyo walxaha bamka ee warshadaha tamarta.
