Low carbon steel

Low Carbon Steel

Low carbon steel, also known as mild steel, is a type of steel that contains a low amount of carbon, typically up to 0.3% by weight.

What is Low Carbon Steel?

Low carbon steel contains the least amount of carbon in the carbon steel family, usually limited to 0.30% or lower. This minimal carbon content gives the steel its mild nature, hence its other common name, mild steel. Due to its low carbon content, mild steel is softer and easier to manipulate compared to higher carbon steels, which makes it well-suited for mass production and various fabrication processes.

Properties of Low Carbon Steel

Low carbon steel offers unique characteristics that set it apart from other carbon steels:

Carburizing and Strengthening

While low carbon steel is generally soft, its surface hardness can be improved through a process known as carburizing. Carburizing involves heating the steel in the presence of a carbon-rich atmosphere, which adds carbon to the surface. This results in a harder surface layer, making the steel more resistant to wear and increasing its load-bearing capabilities.

Common Grades of Low Carbon Steel

Applications of Low Carbon Steel

Low carbon steel’s combination of low cost, ease of manufacture, and adaptability makes it a common choice for numerous products and industries:

Benefits of Low Carbon Steel

Low-carbon steels contain up to 0.30% carbon. A majority of this class of steel is flat-rolled products like sheet or strip; usually they are in a cold-rolled and annealed condition. These steels have high formability as they contain very low carbon, usually less than 0.10% C, with up to 0.4% Mn.

Low carbon steel is a type of steel that has small carbon content, typically in the range of 0.05% to 0.3%. Its reduced carbon content makes it more malleable and ductile than other steel types. Low carbon steel is also known as mild steel. Low carbon steel is one of the most common types of steel.

Hot rolled is relative to the terms of the cold-rolled, cold-rolled is in the recrystallization temperature below the rolling, and the hot rolling is carried out at above the recrystallization temperature rolling.

Advantages

hot rolled can damage the cast microstructure of the steel ingot, refinement of the crystal grains of the steel, and eliminate the defects of the microstructure, so that the the steel organization compacting, improve the mechanical properties.

This improvement is reflected in the rolling direction, so that the steel is no longer to a certain extent isotropic; pouring the formation of bubbles, cracks, and osteoporosis, under high temperature and pressure can also be welded together.

Low carbon steel has the characteristics of short tempering time, softness, stamping resistance and ductility. It easily accepts for various processing such as forging welding and cutting. It is commonly used in the manufacturer of steel bar, stamping parts, chains, rivets, bolts, wire, etc.

Disadvantages

【H】 Ceramic lined pipe

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.

【H】 Cast basalt lined steel pipe

Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.

【H】 Ceramic Tile Lined Pipes

Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.

【H】 Rare earth alloy wear-resistant pipe

The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.

【H】 Tubes Erosion Shields

Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.

【H】 ASTM A213 T91 Alloy Tube

The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
