Carbide formers like Cr,Mo ,will increase that slightly.Also there are trade secrets in the pack ,alkali metals and earths can facilitate carburization and affect C content.High surface C has few applications so most commercial carburization is done in gases and limits surface carbon to numbers like 0.8 %.What is a carbon footprint - definition of carbon footprintA carbon footprint is defined as the total amount of greenhouse gases produced to directly and indirectly support human activities,usually expressed in equivalent tons of carbon dioxide (CO2)..In other words When you drive a car,the engine burns fuel which creates a certain amount of CO2,depending on its fuel consumption and the driving distance.What is Carbon Steel? Properties,Grades,Types of Carbon Carbon steel is steel with carbon content up to 2.1% by weight.The definition of carbon steel from the American Iron and Steel Institute (AISI) states Steel is considered to be carbon steel when no minimum content is specified or required for chromium,cobalt,molybdenum,nickel,niobium,titanium,tungsten,vanadium or zirconium,or any other element to be added to
