Product introduction
Galvanizing refers to the surface of metal, alloy or other materials coated with a layer of zinc to play the role of beautiful, rust prevention and other surface treatment technology. Galvanizing is the process of adding zinc coating to the surface of steel or iron. Because zinc acts as a sacrificial coating, it protects the steel or iron underneath, thus extending the life of metal parts. But galvanizing is a complex process that can be done in a variety of ways. There are different forms of galvanizing, including hot dip galvanizing and hot diffusion galvanizing, and these variations each have advantages and disadvantages. Therefore, it is helpful to understand the different forms of galvanizing before incorporating it into a prototyping or manufacturing project.
Inspection equipment

Material introduction
Low-carbon Steel
Low-carbon steel, commonly known as mild steel, is by far the most common type of steel. Because of its low cost and material properties, low-carbon steel is suitable for a wide range of applications. Low-carbon steel contains approximately 0.05-0.25% carbon, making it malleable and ductile. Mild steel has a low tensile strength, but it is inexpensive and straightforward to form; carburizing can increase surface hardness.
High-strength, low-alloy steels (HSLA) are also categorized as low-carbon steels, with other ingredients including copper, nickel, vanadium, and molybdenum. Together, these can account for up to 10% of the steel composition. As the name implies, high-strength, low-alloy steels have higher strengths due to heat treatment. They also retain ductility, allowing them to be readily formed and machined. HSLA is more corrosion-resistant than regular low-carbon steel.
Medium-carbon Steel
Medium-carbon steel has 0.30 – 0.50% carbon and 0.60 – 1.65% manganese. This steel’s mechanical properties can be enhanced by a heat treatment involving austenitizing, followed by quenching and tempering, giving them a martensitic microstructure.
Heat treatment is only possible on extremely thin portions. However, steel can add additional alloying elements such as chromium, molybdenum, and nickel to increase its capacity to be heat treated and thus hardened.
Hardened medium-carbon steels have greater strength than low-carbon steels but at the sacrifice of ductility and toughness. This steel is mostly used in manufacturing machine components like shafts, axles, gears, crankshafts, couplings, and forgings. Still, it may also be used in rails and railway wheels.
High-carbon Steel
High-carbon steel has 0.60– 1.00% carbon and 0.30 – 0.90% manganese. It possesses the greatest hardness and toughness of carbon steel but the least ductility. Because they are nearly always hardened and tempered, high-carbon steels are extremely wear-resistant. High carbon steels might be employed in springs, rope wires, hammers, screwdrivers, and wrenches.
Tool steels and die steels are high-carbon steels containing extra alloying elements such as chromium, vanadium, molybdenum, and tungsten. The incorporation of these elements leads to particularly tough wear-resistant steel, which is a consequence of the production of carbide compounds like tungsten carbide (WC).
Properties And Applications of Common Carbon Steel Grades
Carbon steel comes in various forms, and can be used in many industries and sectors. Low-carbon steels are frequently used in vehicle body components, structural forms (I-beams, channel and angle iron), pipelines, building and bridge components, and food cans. Medium-carbon steels are frequently used for railway tracks, train wheels, crankshafts, and gears and machinery parts needing this combination of qualities because of their high strength, resistance to wear, and toughness. High-carbon steels are utilized in cutting tools, springs, great-strength wire, and dies due to their high wear resistance and hardness.
Low-carbon, medium-carbon, and high-carbon steel correspond to some common grades. The following table compares several carbon steel grades’ examples, qualities, and applications.
