Common Mild Steels
Mild steel contains 0.16% to 0.29% carbon alloy and is therefore not ductile. Mild steel tubes are coated with copper and are therefore resistant to corrosion, however, extra care must be taken to keep the rust at a distance. The hardness of mild steel can be increased by carburizing, where the steel is heated below its melting point in the presence of another material and then quenched again, hardening the outer surface of the carbon and maintaining a soft core. The most commonly used low carbon steels are - A-106 and A-S3. A-106 belongs to grades A and B and is used in cold or dense coils.
Mild Steel Availability and Uses
Mild steel comes in a variety of structural shapes and can be easily welded into pipes, tubes, tubing, etc. Mild steel pipe and tubing is easy to fabricate, readily available, and relatively inexpensive compared to other metals. When properly protected, this steel has a life expectancy of up to 100 years. Mild steel pipe is used for structural purposes, as well as for mechanical and general engineering purposes. It is also used in potable water supplies and for chlorination and sodium silicate to inhibit corrosion of mild steel pipe.
Often, these pipes are coated with other metals, such as copper, to prevent corrosion. Mild steel pipe and tubing is used for structural applications as well as mechanical and general engineering applications. It is also used in potable water supplies and for chlorination and sodium silicate to inhibit corrosion of mild steel pipe. Extra care is always required to prevent low carbon steel pipe from rusting.
