High Carbon Steel an Low Carbon Steel

And it is the predecessor of branch of China”s oil and gas pipeline science research institute and authoritative pipeline engineering research institute, consists of eight backbone institute and line pipe bureau postdoctoral research stations. Carbon steel is more commonly used than any other metal, and has long been admired for its versatility and low cost. A-106/SA-106 seamless pipe is one of our most popular products.

Pressure pipe applications also include heat exchangers, condenser and boilers. The petroleum industry uses this pipe to carry large amounts of petroleum from the ground to the surface, and this pipe also is commonly used to transfer the petroleum to other places. Many large structures use pipes in the deep foundation, the section that is underground.

Tubes for tubing & casing are manufactured using the hot rolling process. Normally, when iron-based metals like steel are exposed to oxygen, they undergo a chemical transformation, known as oxidation, that changes their properties. Stainless steel is designed to protect against oxidization.

Carbon steel, on the other hand, is characterized by a high carbon content, usually up to 2.1% of its weight. So, what benefits does carbon steel offer? The use of a high carbon content changes the characteristics of steel.

This is why many swords, knives and other bladed weapons are produced with high-carbon steel. In feudal Japan, swordsmiths pioneered a special type of high-carbon steel, tamahagane, for use in weapons like the katana. Even small amounts of moisture, including moisture vapor in the air, can cause carbon steel to rust.

Generally, steel recipes have a weight proportion of carbon in the 0.2% to 2.1% range. Varying proportions of these elements produce steel with targeted values of ductility (the ability of a metal to be drawn into a wire), tensile strength (the ability to be stretched without breaking), and hardness. Carbon steel may contain other agents such as manganese, cobalt, or tungsten, but the proportion of these materials is not specified.

The following shows the four types of carbon steel: However, carbon steel has relatively inferior ductility specs. Corrosion is an oxidation of the metal to a more stable molecular state that results in a weakening of the base steel.

Stainless steel is a unique form of steel which does not corrode. Most forms of stainless steel have a mass proportion of 10.5% to 11.0% chromium. With the use of chromium, stainless steel has the basic properties of steel with the addition of its inability to rust.

When a pipe extruded, the ability to maintain specs depends on the ductility of the material, which is similar for both alloys. Pipe fittings are generally milled, and metalworkers can again expect similar results between the two materials. Like stainless steel, aluminum does not corrode.

Reactivity – for applications requiring no reactivity, stainless steel is the clear choice. Carbon steel (and aluminum) reacts with food, producing flavor changes and potential health hazards. Stainless steel does not cause these interactions.
