Na-ekpo ọkụ: Iji belata mgbagha na nrụgide na nnukwu ngwaọrụ ma ọ bụ mgbagwoju anya jiri ọkụ ọkụ okpukpu abụọ. Okpomọkụ n'ọkwa na-agaghị agafe 400°F kwa elekere (222°C kwa elekere) ruo 1100°F (593°C) hahahaha, wee kpoo ruo 1450-1550°F (788-843°C). Maka ngwaọrụ nkịtị, jiri naanị oke okpomọkụ nke abụọ dị ka otu ọgwụgwọ ikpo ọkụ.

Ịkwado (Ọkụ dị elu): Kpoo ọkụ ngwa ngwa site na preheat.
For Cutting Tools:
Ọkụ: 2200-2250°F (1204-1232°C)
Nnu: 2175-2225°F (1191-1218°C)
Iji mee ka ike sie ike, jiri okpomọkụ kacha ala.
Iji mee ka ike siri ike dị ọkụ, jiri okpomọkụ kachasị elu.
For punches, dies, and tools that require maximum
toughness without hot hardness:
Ọkụ: 2075-2175°F (1175-1191°C)

Na-emenyụ: Gas nwere nrụgide, mmanụ ọkụ, ma ọ bụ nnu. Maka gas na-agbanye nrụgide, ọ̀tụ̀tụ̀ nkwụsịtụ ọsọ ọsọ ruo n'okpuru 1000°F (538°C) dị oké mkpa iji nweta ihe ndị a chọrọ. Maka mmanụ, menyụọ ruo oji, ihe dị ka 900°F (482°C), wee dị jụụ n'ikuku ruo 150 -125°F (66-51°C). Maka nnu nke edobere na 1000-1100°F (538-593°C), haha ​​nhata, wee dị jụụ n'ikuku ruo 150 -125°F (66-51°C).

Na-ewe iwe: Iwe ozugbo emenyụchara. Oke okpomọkụ a na-ahụkarị bụ 1025-1050°F (552-566°C). Jide na okpomọkụ maka awa 2, wee mee ka ikuku dị jụụ ruo okpomọkụ. Achọrọ iwe ọkụ ugboro abụọ. Maka nnukwu akụkụ obe, na karịsịa maka oghere ndị a ga-eji waya EDM gbutu ngwaọrụ, a na-atụ aro iwe ọkụ ugboro atọ.
