ASTM A106 Gr.C Pipes
ASTM A106 Gr.C Pipes - industrial steel pipe
Material for Mining & Industrial Equipment
Professional carbon steel extend component lifespan in harsh industrial conditions.
Carbon steel is an alloy made primarily of iron and a small amount of carbon, typically between 0.05% and 2.0% by weight. It is the most widely produced type of steel in the world, used in everything from car frames to kitchen knives. What makes it “carbon steel” rather than another type of steel is simple: carbon is the main element added to iron to change its properties, with minimal amounts of other alloying elements like chromium or nickel.
Carbon steel is valued for its high strength, durability, affordability, versatility, and recyclability, making it a preferred material across industries.
Carbon steel is a material that is still widely used today in modern engineering, due to its combination of high mechanical strength, high fabrication flexibility and economic value. It is versatile and can be used for various purposes, such as building structures, manufacturing industrial components, and creating decorative features.

Carbon steel is grouped by carbon content, and this directly influences its strength, hardness, formability and performance. A grasp of these classifications enables professionals to choose materials for a project in the most effective manner.
Carbon Content: ≤ 0.30%
Provides high formability, excellent weldability and low cost. Widely used for general fabrication and structural components.
Carbon Content: 0.30% – 0.60%
Offers greater strength and wear resistance while maintaining reasonable machinability. Suitable for machine parts and axles.
Carbon Content: 0.60% – 1.00%
Delivers high hardness and toughness for critical mechanical components requiring durability under cyclic loading.
Carbon Content: > 1.00%
Provides exceptional hardness and abrasion resistance for special industrial components and wear-intensive applications.
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
