Gas Carburizing Mild Steel: A Strong, Better Option

Summary for gas carburizing mild steel Discussion

Gas carburizing mild steel is presented as a direct substitute for pack carburizing in this thread. Muhammed Hanifa, who makes excavator gears and pinions and currently heat treats them by traditional pack carburizing, asks whether fabricated mild-steel parts can be gas carburized or whether conventional carburizing is the only option. The reply is clear: yes, gas carburizing can be used to replace pack carburizing in every case, according to the answerer. The answer also notes a likely practical benefit: gas carburizing should give more uniform results. No limitations or exceptions are discussed in the excerpt, so the discussion is brief and one-sided, focused on confirming that mild steel parts can be carburized by gas rather than pack methods.

Q. Hi,
We are a workshop making excavators gears and pinions. We heat treat them with traditional carburizing (pack carburizing). We use mild steel to make these gears and pinions. Is it possible to gas carburize these parts having them fabricated using mild steel? Or conventional carburizing is the only method for mild steel. Please help.

A. Yes, of course gas carburizing can be used to replace pack carburizing in every case. And you will probably get more uniform results.
