The ASTM A500 specification covers cold-formed welded and seamless carbon steel structural tubing in round, square, rectangular, and "special" shapes for construction and engineering purposes. This specification is applicable to steel tubing for mechanical, structural, and pressure applications.
Carbon steel is a type of steel that contains carbon as the main alloying element, with other elements present in smaller amounts. This metal is commonly used in the manufacturing of many products and structures due to its high strength and low cost.
Carbon steel can be further classified into various grades based on its chemical composition and mechanical properties, such as low carbon steel (mild steel), medium carbon steel, high carbon steel and ultra high carbon steel. Each grade has its own specific uses and applications, depending on the desired properties of the final product.
High Carbon Steel: The carbon content is usually between 0.60% and 2.00%. High carbon steel has high strength and hardness, but low ductility and toughness, and poor weldability. Commonly used high carbon steels include 65mn, t8, t10, etc.
How Can You Tell if Tube Is High Carbon Steel Tube
There are several ways to determine if pipe is high carbon steel tube:
Spark Test: One way to identify high carbon steel tube is to do a spark test. High carbon steel tube produces a distinct spark pattern that is different from other metals. The sparks produced by high carbon steel tube are short, bright, and white in color.
Magnet Test: High carbon steel tube is magnetic, so if a magnet sticks to the metal, it may be an indication that it is high carbon steel tube.
Visual Inspection: High carbon steel tube typically has a higher carbon content than other types of steel, which can make it appear darker in color and have a more matte finish.
Hardness Test: High carbon steel tube is generally harder than other types of steel, so a hardness test can help determine if a metal is high carbon steel tube. A common method is the rockwell hardness test, which involves indenting the surface of the metal with a diamond or tungsten carbide ball and measuring the depth of the indentation.
Material of High Carbon Steel Tube
Iron and carbon are the most abundant materials present in steel. Pure iron is not particularly strong or hard on its own, so it is the addition of carbon that helps give steel its great strength.
The crude iron used to produce steel has a relatively high amount of carbon. Its carbon composition can be as high as 2.1%, which is the greatest amount of carbon a material can contain and still be considered steel.
Iron can be processed further to reduce carbon. This manipulation of carbon alters several material properties, including:
● Strength: The load a material can bear, measured by yield point and tensile strength. Yield point is the point at which a material deforms, but does not break, and tensile strength is the amount of stress needed to actually break a material.
● Ductility: The amount a material can be stretched without becoming brittle. Ductility is measured by elongation, which is the percent the length of a material increases before it breaks.
● Hardness: The wear resistance of material and machinability of material. This is usually measured on the rockwell hardness scale or brinell hardness scale.
The carbon present in steel is typically reduced so that it fits into three main categories of carbon steel: Low (or mild), medium and high carbon steel.
Carbon Steel Tube Types
There are several types of carbon steel, each with unique properties and applications. These types include:
Low carbon steel
Also known as "mild steel," this type of steel is more ductile and easier to shape, form and weld compared to other carbon steel types. This makes mild steel a popular choice over higher-carbon steels when it comes to construction and manufacturing applications.
Medium carbon steel
Contains 0.3% to 0.6% carbon content, making it stronger and harder than low-carbon steel but also more brittle. It is often used in applications that require both strength and ductility.
High carbon steel
High carbon steel contains 0.6% to 1.5% carbon content and is known for its high strength and hardness, but high carbon steel is even more brittle than medium-carbon steel. High carbon steel is used in applications that require high strength.
Manufacturing Process of High Carbon Steel Tube
The manufacturing process for carbon steel varies depending on the type of steel and the intended qualities for the final product. The manufacturing process is often divided into three stages:
Steel can be created entirely from recycled material or from a mix of recycled and virgin steel using the BOF process.
Mild and carbon steel are commonly produced using the basic oxygen furnace (BOF) method, which involves the transformation of raw materials such as iron ore and coke into liquid steel.
The liquid steel is poured into moulds to produce slabs or ingots. Pure oxygen is pushed through the liquid steel to oxidise the extra carbon, resulting in a finished product with a carbon content of up to 0.5%.
Market needs for higher-quality steel products with more consistent characteristics fuelled the development of secondary steelmaking processes.
In an electric arc furnace, steel composition is changed by adding or removing specific components or by manipulating the temperature. EAF processes involve:
● Stirring – Separating non-metallic impurities guarantees a homogenous combination and composition of the steel.
● Ladle furnace – Enables precise temperature control and the measured injection of alloy components.
● Ladle injection – Inert gas is injected into the bottom of the steel bath to achieve a stirring effect.
● Degassing – Removes hydrogen, oxygen and nitrogen while also lowering the product's sulphur content.
● Composition adjustment – Crucial to achieve stirring (by sealed argon bubbling with oxygen blowing - CAS-OB).
The elimination of oxygen is a vital step in secondary steelmaking. As molten steel begins to solidify, the presence of oxygen causes a reaction with carbon, producing carbon monoxide gas.
Controlling deoxidation can be used to change the material properties of the final product and hence the steel's suitability for various desired applications. Deoxidising steel processes involve:
● Rimming steels – Non-deoxidised or partially deoxidised steels.
● Capped steels – Initially comparable to rimming, but the mould is capped to prevent the creation of carbon monoxide.
● Semi-killed steels – Partially deoxidised and have a carbon content in the range of 0.15–0.3%.
● Killed steels – Totally deoxidised to the point where no carbon monoxide is produced during solidification.

Affordability Compared To Other Materials
High carbon steel tube often present a more economical option when evaluating the cost. Their production process and abundant raw materials contribute to a competitive price point, especially compared to alternatives like stainless steel or specialty alloys. This cost-efficiency is particularly beneficial for expansive projects or when sourcing materials in bulk.
Ease Of Fabrication And Modification
Given its properties, carbon steel offers flexibility in its shaping and adaptation. This material can be easily welded, cut, and molded to fit various specifications and requirements. Such malleability proves advantageous for industries and projects that require customized piping solutions.
Resistance To Wear And Tear
Despite its affordability, carbon steel doesn't compromise on longevity. These pipes resist the typical wear and tear seen in industrial and infrastructural applications, ensuring a longer operational life and reducing the frequency of maintenance or replacements. Whether it's the movement of particulate-heavy fluids or exposure to high traffic conditions, high carbon steel tube prove their mettle by standing resilient.

Steel Pipe Materials: High-quality carbon steel materials should be selected. These materials have good strength, toughness and corrosion resistance and can meet the usage requirements of the pipeline system.
Steel Pipe Specifications: Appropriate steel pipe specifications, such as pipe diameter, wall thickness, etc., need to be selected based on actual needs to ensure that the pipeline system can meet the flow and pressure requirements.
Surface Treatment: The surface of carbon steel pipes needs anti-corrosion treatment. Common treatment methods include spray painting, galvanizing, plastic coating, etc. These treatment methods can effectively improve the corrosion resistance and service life of the pipeline.
