World Steel Grade Comparison Table of Alloy Tool
Steel is an alloy of iron and other elements, mainly carbon. Steel, also known as alloy steel, is generally classified as an alloy of carbon and other elements, mainly chromium, molybdenum, vanadium, nickel, cobalt, and a few other metals. Steel is a very useful material that can be applied in many diverse industries, from the automotive parts industry to the medical instrument industry. Steel is also extremely strong and durable, making it an excellent choice for engineering and manufacturing in many different ways.
Steel is divided into different types, including carbon, high-alloy, and stainless steel. The classification of steel is based on its composition, structure, and properties. In the alloy tool steel industry, steel grades are typically categorized into three main groups: low alloy, medium alloy, and high alloy. Each of these groups has its own unique characteristics, such as strength and durability, and is used for different applications and industries.
Low Alloy Steel: Low alloy steel, also known as low carbon steel, contains less than 0.2 percent carbon and can be formed very easily and is difficult to strengthen by heat treatment. Low alloy steel is generally used for applications requiring greater toughness and ductility than high alloy steel. Low alloy steel is also very resistant to corrosion and can be used in a variety of environments. Low alloy steel has many different grades, such as 1018, 1020, 1035, 1045, and 4140.
Medium Alloy Steel: Medium alloy steel, on the other hand, contains up to 0.7 percent carbon and is commonly treated with heat or induction hardening to increase its strength and hardness. This type of steel is commonly used for general engineering and construction, as well as industrial and manufacturing applications. Medium alloy steel is typically available in grades such as 4130, 4140, 4330, 4340, 6150, and 8620.
High Alloy Steel: High alloy steel contains a higher amount of carbon and other alloying elements, such as chromium, molybdenum, vanadium, and nickel. This type of steel is much harder and more difficult to work with, but is often the best choice for certain applications requiring increased strength and wear resistance. High alloy steel is commonly used in jet engines and high-performance car parts. High alloy steel grades include AISI D2, AISI D3, AISI H13, and AISI M2.
There are several methods for determining the steel grade. One of the most common ways to classify steel grades is by using standard steel grade notations such as SAE-AISI and ASTM. Standardization across the steel industry is critical, as it allows for easier identification and comparison of different steel grades. Different organizations such as the American Iron and Steel Institute (AISI) and the Society of Automotive Engineers (SAE) have different methods for classifying steel.
The most important thing to remember when selecting steel is to make sure that you select the right grade for the specific application. If you are unsure which grade to use, it is best to consult a steel manufacturer or supplier to help you determine the right grade for your needs. With the right grade of alloy steel, you can be sure that your project will last and meet all the requirements of your specific application.
