Question

Up to what amount of carbon content in steels, can they be treated by oxygen cutting?

(a) 0.3%

(b) 0.2%

(c) 0.7%

(d) 0.4%

This question was addressed to me in unit test.

This intriguing question originated from Oxygen Cutting in section Welding and Related Processes of Casting-Forming-Welding II

Answer 1

Right answer is (c) 0.7%

For explanation I would say: For a steel to be treated by oxygen cutting process, the carbon content that should be available in terms of percentage composition is around 0.7%, that is, the steel that can be treated by this process is a high alloy steel.
