Babban rarrabuwa na steels kuma da jinsin

gami da na baƙin ƙarfe, da carbon tare da wani abun ciki na ba fiye 2.14% da aka kira karfe. Akidar karfe halaye: ƙarfi, ductility, tauri, elasticity, karko, da sauransu. Babban rarrabuwa na karfe ne m da:

• Chemical abun da ke ciki.
• Tsarin abun da ke ciki.
• Quality karfe ko gami (dangane da adadin cutarwa impurities da kuma wani hanya ne na samarwa).
• A mataki na deoxidation.
• Alƙawari.

sinadaran da abun da ke ciki

Dangane da adadin carbon a cikin gami abun da ke ciki na rarrabe carbon kuma gami steels. A carbon abun ciki a cikin da iri da kuma yadda suke alamar alama da Gost. Nau'in carbon karfe ne zuwa kashi:

• M (da abun ciki na C (carbon) ne kasa da 0.3%).
• Sredneuglerodistoj (ciki C - daga 0.3 zuwa 0.7%).
• High-carbon (ciki C - fi 0.7%).

A gami da aka gabatar da wasu fiye da babban aka gyara da kuma Additives, musamman sinadaran abubuwa (nickel, chromium, molybdenum, aluminum, boron, vanadium, thallium, da dai sauransu) cewa samar da wani Hadakar doping. Bi da bi, da rarrabuwa na gami steels highlights:

• Low gami (dauke da kasa da 2.5% na gyara na gami karfe).
• Srednelegirovannye (dauke daga 2.5 zuwa 10% na gyara na alloying karfe).
• High-gami (dauke da sama da 10% na gyara na gami karfe).

Nau'in steels ga tsarin abun da ke ciki

Karfe, haƙĩƙa, sun shige cikin doping tsari ne zuwa kashi azuzuwan bisa ga tsarin abun da ke ciki. A tsarin da gami dogara da carbon abun ciki, alloying abubuwa da sanyaya kudi bayan dumama zuwa 900 ⁰S. Akwai biyar nau'ukan tsarin abun da ke ciki:

Nau'in steels Quality

• Talakawa ingancin (abun ciki na S (sulfur)> 0,06%, P (phosphorus) <0,07%).
• Quality (abun ciki na S (sulfur)> 0,04%, P (phosphorus) <0,35%).
• High quality (abun ciki na S (sulfur)> 0.025%, P (phosphorus) <0,025%).
• Musamman high quality (abun ciki na S (sulfur)> 0.015%, P (phosphorus) <0,025%).

Ga talakawa ingancin steels hada da carbon, kudin da fasaha halaye da suke muhimmanci na baya steels sauran azuzuwan.
