Nkedo ígwè na-nkewa dị ka ha chemical mejupụtara na-ekewa n'ime igba carbon ígwè mgbatị akụkụna igba alloy ígwè mgbatị akụkụ. Dị ka nhazi ọkwa nke ojiji e ji mee ihe, ígwè ọgbụgba nwere ike kewaa n'ime injinịa na nhazi ihe nkedo ígwè (carbon alloy steel and alloy structural steel), tụba akụkụ nchara pụrụ iche (nchara nchara na-eguzogide igwe, nchara na-eguzogide okpomọkụ, nchara na-eguzogide , alloy based alloy) na ihe nkedo nkedo ígwè (ihe eji eme ihe igwe, ihe nchara). Na ụlọ ọrụ ebe a na-ekepụta ihe, ihe ndị eji eme ihe eji eji igwe eme ihe bụ nkewa dịka ndị a:
1) igba carbon nchara: igba obere carbon ígwè, igba ajụ carbon ígwè, igba elu carbon ígwè (elu ike carbon nchara)
2) Ọkara-alloy nchara na ala-alloy nchara maka nkedo: igba nchara manganese, igba silico-manganese nchara, igba ntụtụ manganese-molybdenum nchara, nkedo manganese-molybdenum-vanadium ọla kọpa, igba chromium ígwè, chromium-molybdenum igba ígwè, chromium -manganese-silicon cast steel, chromium-manganese Molybdenum igba nchara, chromium molybdenum vanadium igba nchara, chromium ọla kọpa igba ígwè, molybdenum igba nchara, chromium nickel molybdenum igba ígwè, wdg Dị iche iche chemical ọcha nwere ike rụọ ọrụ dị iche iche iji melite arụmọrụ kwekọrọ . N'isiokwu ndị na-esonụ, anyị ga-ewebata ngwongwo nke ngwongwo alloy ndị metụtara ya na ọrụ ndị ihe kemịkal jikọtara n'otu n'otu.
3) Nchara nchara na-eguzogide corrosion: igwe anaghị agba nchara, martensitic anaghị agba nchara, austenitic anaghị agba nchara na austenitic-ferritic duplex igwe anaghị agba nchara.
4) Nchara na-eguzogide okpomọkụ: nchara nchara chromium, nchara nchara chromium na nchara nchara dị elu.
5) Eyi na-eguzogide nkedo ígwè: eyi na-eguzogide manganese ígwè, eyi na-eguzogide chromium ígwè
6) Nkedo ígwè na ọkachamara ọkachamara: igwe ihe nkedo dị ala, ihe eji arụ ọrụ ígwè (ịnwụ anwụ), mgbatị mgbatị, nkenke mgbatị, nkedo nkedo nkedo.
