Steel is one of the most essential materials used in industrial and commercial applications, thanks to its combination of strength and flexibility. Steel is a form of iron alloy, which is combined with other elements to improve its strength, formability, and durability. While there are many types of steel, such as carbon steel and stainless steel, one of the most commonly used steel grades is International Cast Steel (ICS). In this article, we explore what ICS steel is and why it is important for a range of construction applications.
International Cast Steel (ICS) is a type of cast steel that is formulated to the standards of ASTM A743-05. ICS can be divided into several grades, from low-alloy steel to high-alloy steel. Low-alloy steel contains 0.8% to 1.25% carbon and minimal amounts of other alloying elements, while high-alloy steel contains 1.25% to 2.25% carbon and other alloying elements, such as chromium, vanadium, and molybdenum. ICS is a general purpose steel that is commonly used in casting. It is typically used to manufacture items such as valves, crankshafts, gears, and machine parts.
One of the major benefits of ICS is its ability to withstand corrosion and resist wear and tear. This is due to the presence of alloying elements, which helps to enhance the mechanical properties of the steel. Additionally, the steel can be heat treated or tempered, to increase its tensile strength, fracture toughness, and fatigue strength. This makes it a popular choice for heavy-duty engineering materials, particularly for parts used in naval, structural, and automotive applications.
Another benefit of ICS is its low cost. The production of ICS is much less labor-intensive than that of carbon steel or stainless steel, due to its lower melting temperature and shorter manufacturing time. Additionally, casting is generally less expensive than other steel forming processes, such as forging, which can also help to keep costs down.
Despite its many advantages, ICS has some drawbacks. The steel is not as ductile or machinable as carbon steel or stainless steel, making it difficult to work with after it has been cast. Additionally, ICS must be heated in order to gain the desired strength and dimensional accuracy, which can be energy-consuming. Finally, ICS has a higher scrap rate than other steel grades, as even a slight discrepancy in the melting temperature can cause flaws in the final product.
Despite its drawbacks, ICS steel is still an important component in many industrial and commercial applications. It is versatile, cost-effective, and durable, making it an ideal material for a range of engineering applications. Its ability to withstand corrosion, its low cost, and its good machinability also make it an attractive choice for many parts and components. For all these reasons, ICS continues to be an important part of the steel industry.
