ot rolled mild steel seems to have a wider tolerance for amount of included carbon than cold rolled, making it a bit more problematic to use as a blacksmith. Also for similar metals, hot rolled seems to typically be less costly.

ApplicationsHot rolling is used mainly to produce sheet metal or simple cross sections, such as rail tracks

Hot-dip galvanisation is a form of galvanisation. It is a usually dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements. Galvanized steel is widely used in applications where rust resistance is needed, and can be identified by the crystallization patterning on the surface (often called a spangle).

Applications

• Construction and building:roofing; ventilating duct; handrail; partition panel, etc
• Further processing:coating base plate
• Electric appliance:Refrigerator; washing machine; recorder; microwave, etc

Cold-rolled sheets and strips come in various conditions: full-hard, half-hard, quarter-hard, and skin-rolled. Full-hard rolling reduces the thickness by 50%, while the others involve less of a reduction.Skin-rolling, also known as a skin-pass, involves the least amount of reduction: 0.5-1%. It is used to produce a smooth surface, a uniform thickness, and reduce the yield point phenomenon (by preventing Lders bands from forming in later processing).

Applications

• Domestic & Appliances
• Oil barrels & containers
• Washing Machines & geyser
• Electronics & Electrical components
• Bicycles
• Automobiles
• Refrigerators

Mild steel, also called plain-carbon steel, is the most common form of steel because its price is relatively low while it provides material properties that are acceptable for many applications, more so than iron. Low carbon steel contains approximately 0.050.15% carbon and mild steel contains 0.160.29% carbon; making it malleable and ductile. Mild steel has a relatively low tensile strength, but it is cheap and malleable; surface hardness can be increased through carburizing

ApplicationsMild steel is used for almost all non-specialist steel products cars, domestic goods, constructional steel. street `furniture` signs etc Fence posts, wire, plate , tin cans. key rings
