What is Carbon Steel?

Carbon steel is an iron-carbon alloy, which contains up to 2.1 wt.% carbon. For carbon steels, there is no minimum specified content of other alloying elements, however, they often contain manganese. The maximum manganese, silicon, and copper content should be less than 1.65 wt.%, 0.6 wt.% and 0.6 wt.%, respectively.

What Are The Types Of Carbon Steel?

Low-carbon steel

Low-carbon steel is the most widely used form of carbon steel. These steels usually have a carbon content of less than 0.25 wt.%. They cannot be hardened by heat treatment (to form martensite) so this is usually achieved by cold work.
Carbon steels are usually relatively soft and have low strength. They do, however, have high ductility, making them excellent for machining, welding, and low cost.
High-strength, low-alloy steels (HSLA) are also often classified as low-carbon steels, however, also contain other elements such as copper, nickel, vanadium, and molybdenum. Combined, these comprise up to 10 wt.% of the steel content. High-strength, low-alloy steels, as the name suggests, have higher strengths, which are achieved by heat treatment. They also retain ductility, making them easily formable and machinable. HSLA is more resistant to corrosion than plain low-carbon steels.

Medium-carbon steel

Medium-carbon steel has a carbon content of 0.25 – 0.60 wt.% and manganese content of 0.60 – 1.65 wt.%. The mechanical properties of this steel are improved via heat treatment involving austenitizing followed by quenching and tempering, giving them a martensitic microstructure.
Heat treatment can only be performed on very thin sections, however, additional alloying elements, such as chromium, molybdenum, and nickel, can be added to improve the steel's ability to be heat-treated and, thus, hardened.
Hardened medium-carbon steels have greater strength than low-carbon steels, however, this comes at the expense of ductility and toughness.

High-carbon steel

High-carbon steel has a carbon content of 0.60– 1.25 wt.% and manganese content of 0.30 – 0.90 wt.%. It has the highest hardness and toughness of carbon steel and the lowest ductility. High-carbon steels are very wear-resistant as a result of the fact that they are almost always hardened and tempered.
Tool steels and die steels are types of high-carbon steels, which contain additional alloying elements including chromium, vanadium, molybdenum, and tungsten. The addition of these elements results in very hard wear-resistant steel, which is a result of the formation of carbide compounds such as tungsten carbide (WC).

What is Carbon Steel Flanges?

Carbon Steel Flanges manufacturer of different Carbon steel materials. There are different grades to the Carbon steel depending on the material composition and the mechanical properties vary. Fitwel Industries LLP is a leading manufacturer and supplier of these flanges. Carbon Steel Flange is a forged, or it is called a cast ring which is designed to connect different sections of the pipe or any other machinery that requires an intermediate connecting point. These flanges are in massive demand in the market because of their tensile strength and surface finishing.

What Are Carbon Steel Flanges Used For?

A Carbon Steel Class 150 flange Mumbai is a method of connecting pipes, valves, pumps, and other equipment to form a piping system. It also provides easy access for cleaning, inspection, or modification. Carbon Steel Flanges are usually welded or screwed. Flanged joints are made by bolting together two Flanges with a gasket between them to provide a seal.

There Are Various Types of Carbon Steel Flanges

Our manufacturing facilities are well equipped to manufacture various types of flanges namely:

Carbon Steel Slip On Flange

These are easily fitted and welded into different pipes. Slip on pipe flange is slipped over the Pipe and then welded both inside and outside to provide sufficient strength and prevent leakage. These flanges are ideal for lower pressure applications.

Carbon Steel Weld Neck Flange

Carbon Steel Weld Neck flanges have a long tapered hub and are often used for high pressure applications. These flanges are designed to be joined to a Piping system by Bun Welding. The Neck, or Hub, transmits stresses to the Pipe, reducing stress concentrations at the base of the Flange.

Carbon Steel Blind Flange

A Carbon Steel Blind flange is a round plate that has all of the relevant boltholes but no centre hole, and because of this feature this flange is used to close off the ends of the piping system and pressure vessel openings. It also permits easy access to vessels or Piping systems for inspection purposes.

Carbon Steel Socket Weld Flange

These Carbon Steel Socket Weld Flanges are attached by inserting the pipe into the socket end. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. Socket-weld pipe flanges are mainly used for smaller sizes of high-pressure pipes.

Carbon Steel Threaded Flange

Carbon Steel Threaded flanges are similar to slip-on pipe flanges except the bore of threaded pipe flange has tapered threads. These flanges are ideal for relatively low pressure piping systems. Threaded flanges are used with pipes that have external threads. The benefit of these pipe flanges is that they can be attached without welding.

Carbon Steel Lap Joint Flange

Carbon Steel Lap Joint Flanges slide over the pipe and are most commonly used with Stub End Fittings. A pipe is typically welded to the Stub End and the Lap Joint pipe flange is free to rotate around the stub end. Lap Joint pipe flanges are often used for applications that require frequent dismantling. Threaded pipe flanges are often used for small diameter, high-pressure requirements.

Carbon Steel Orifice Flange

Carbon Steel Orifice Flanges are used instead of standard pipe flanges when an orifice plate or flow nozzle must be installed. Pairs of pressure tappings are machined into the orifice flange, making seperate orifice carriers or tappings in the pipe wall necessary.

In addition to these we also manufacture Orifice Flange, Stub-end fittings, plate flanges, backup flanges, Beveled ID flanges, and Reducing flanges.
