Steel Classes: Carbon steel (≤2.1% carbon; low alloy) Stainless steel (+chromium) Maraging steel (+nickel) Alloy steel (hard) Tool steel (harder) Wrought iron is commercially pure iron. In contrast to steel, it has a very low carbon content. It is a fibrous material due to the slag inclusions (a normal constituent)

weldability of materials - castirons - twi

Remove slag and peen each weld bead whilst still hot. Fill the groove using nickel (3 or 4mm diameter) or nickel-iron electrodes for greater strength. Finally, to avoid cracking through residual stresses, the weld area should be covered to ensure the casting will cool slowly to room temperature

heap leaching-wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the

incineration process- an overview | sciencedirect topics

In incineration process, fly ash is the major reaction surface of dioxin formation, and the metal, metal oxides and metal chlorides on the surface will promote the formation of dioxin.Therefore, fly ash greatly affects the formation paths. It is confirmed that a small proportion of dioxins will be discharged with flue gas and most remained in fly ash, which may be in the range from 106 to 258
