Steel heating is sometimes utilized for altering carbon content. Upon heating of steel within oxidizing environment, oxygen makes a combination with iron for forming iron-oxide layer. This layer protects steel from the decarburization. Upon conversion of steel into austenite, oxygen & iron combine for forming slag that does not provide any protection against decarburization. Formation […]
