[email protected]Blister steel used by Huntsman as raw material was made by the cementation process or by carburization of iron. Carburization is a heat treatment process, in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder.

Get QuoteNov 27, 2019 Steel, for example, is both harder and stronger than pure iron. And unlike iron, steel isnt an essential mineral. You dont need to consume steel as part of your diet. The primary difference between iron and steel is that the former is a metal, whereas the latter is an alloy. Iron is simply a metal element that occurs naturally on Earth.

Get QuoteCast iron is an iron alloy containing 2 wt. 4 wt. carbon, 1 wt. 3 wt. silicon and smaller amounts of minor elements 1. In comparison, steel has a lower carbon content of up to 2 wt. and a lower silicon content. Cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before being cast.

Get QuoteThe process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel.
