Steel is one of the most versatile products as it can be fabricated into any shape. Do you know why the welding process is more prevalent in the steel industry? Welding is a process where you can fuse two or more steel products into a single product through pressure, heat, or both. Many steel dealers in Chennai find welding the prime solution for fabricating metals in pharmaceuticals, petrochemicals, food and beverage, and related industries. One of the significant concerns in carbon steel is they don’t distribute the heat evenly. Thus, it makes the carbon steel rust, embrittlement, and warping. Hence, in this post, let us see some welding tips to fabricate carbon steel for even heat distribution.

Right filler metal:

The foremost welding tip to fabricate carbon steel is to choose the suitable filler metal. The filler metal refers to the unalloyed or alloy metals that are heated, melted, liquified, and allowed to flow between the space of two joining metals. This filler metal gives the welded metals the required strength and corrosion resistance. So, the filler metal that you will use to weld the carbon steel can affect the output material’s quality and strength. Thus, to choose the suitable filler metal, first, consider the dimension of the metal that is going to be welded and the filler metal. The filler metal should be thinner or equal to the base metal; otherwise, the weld will be too weak.

Similarly, the base and filler metal should have the same chemical composition because different chemical properties can weaken the welding process. For example, if you are welding 316 austenitic stainless steel, the steel suppliers use 316L metal as a filler metal. The letter “L” refers to the low carbon content and trace level.

Preparations:

Another excellent tip to consider in fabricating carbon steel is proper welding preparation. We all know that carbon steel is one of the sensitive steel and gets contaminated by dirt and dust particles easily. So, while welding the carbon steel, make sure that your workstation and instruments are clean enough. If not proper preparation is done, it can consecutively reduce the corrosion resistance and strength of the metal. Similarly, use a brush dedicated only to clean the carbon steel. The JSW steel dealers in Chennai offer the best carbon steel for various industrial and commercial purposes.

Gas coverage:

Thirdly, give the welding the maximum gas coverage to reduce the oxidation level. While welding the metal, use enough shielding gas and a bigger face shield rather than increasing the gas input. Similarly, ensure that the input gas or shielding gas should be chosen wisely because it can affect the properties of the metals. The shielding gas combinations commonly used are argon and carbon dioxide, helium, argon, and carbon dioxide or argon and oxygen.

Hence, use these tips to fabricate your carbon steel effectively with proper heat distribution. Bharat Steel is the best steel dealer in the city, offering products like SAIL TMT bar, steel tubes, pipes, and many more with high quality and precision.

Have you ever heard of ductile iron pipes? If not, here is a short description of the iron pipes. Ductile iron is a metal made from crude iron where the iron ore is smelted in a blast furnace to obtain the product. It has high carbon content and stable chemical properties. You may think, why is it called ductile iron? The graphite in the ductile iron has round nodules which suppress the cracks and enhance its ductile property. On the other hand, steel pipes are made from steel ore and undergo a process of molding and welding to meet the requirements. These are the most utilized products by manufacturers and steel suppliers in Chennai. The tubular sections in the steel have high strength naturally, which withstand the longitudinal stress and the bending forces.

However, the ductile iron and steel pipes may look similar at first glance. But they do have differences that make the steel pipes stand out. Hence, in this post, let us see why one should choose steel pipes over ductile iron pipes.

Carbon content:

The foremost difference between ductile pipes and steel pipes is the carbon content. The carbon content can be a blessing and curse at the same time because the higher the carbon content, the more the metal has hardness and strength. But at the same time, the product is subjected to brittleness and weldability. So, in the case of ductile iron pipes, they have a carbon content of around 3.0%-3.9%, whereas the iron pipes have carbon content ranging from 0.8% to 0.60%. However, JSW steel dealers in Chennai prefer steel pipes, even though they have less carbon content, they are not brittle and weldable.

Tensile strength:

Another prime difference between ductile iron and steel pipes is tensile and yield strength. The tensile strength defines the maximum load a metal can withstand while undergoing external pressure without being fractured or cracked. The tensile strength of the ductile iron ranges from 42,000 psi to 80,000 psi. But the tensile strength of the steel pipe is around 60,000 psi to 100,000 psi. Not only pipes, but even steel SAIL TMT bar also have tensile above 100,000 psi.

Yield strength:

Thirdly, ductile iron and steel pipe differ based on yield strength. The yield strength refers to the level of stress. It means by the time the metal reaches the saturation point or a level the metal would have undergone a deformation. The yield strength of the ductile iron is lesser or equal to 350 MPa, whereas for the steel pipes, it is around 290 MPa – 550 MPa. All the steel products have good yield strength, for example, the MS chequered plate has a good yield strength of around 540MPa.

Hence, these are the major differences between ductile iron and steel pipes. Even though they look alike, it is always to choose the appropriate one depending upon your project and application. Therefore, approach Bharat Steel, the best steel suppliers in Chennai, for quality steel products.
