Introduction
Chinese 45Mn2 steel is an alloy steel which is usually used to make various machine parts and tools. 45Mn2 steel is a medium carbon steel with relatively high hardness and good strength. It has good cold forming properties and can be welded and heated. It is also known as 15CrMn alloy steel.
History
45Mn2 steel is a type of alloy steel which was developed in the 1970s in China for the purpose of making machine parts that were strong and durable enough to withstand pressure and tough tasks. This type of steel is made up of a combination of elements, including carbon, manganese, phosphorus and sulfur. 45Mn2 steel was the first type of steel produced in China and it was developed to replace carbon steel, which had been used extensively in the past.
Composition
45Mn2 steel is composed of the following chemical elements: Carbon, 0.42-0.50%; Silicon, 0.17-0.37%; Manganese, 0.90-1.20%; Chromium, 0.30-0.45%; Nickel, 0.50%; Molybdenum, 0.15%; Phosphorus, 0.03%; Sulfur, 0.03%.
Properties
45Mn2 steel has a number of advantages when compared to other types of steel. It is very strong and durable, which makes it suitable for use in the manufacture of machine parts and tools. It has good cold forming properties, making it easy to shape into the desired shapes and sizes. In addition, it has good welding and hardening properties, making it easy to join and make permanent changes.
Application
45Mn2 steel is used in a variety of applications because of its strength and durability. It is commonly used to make agricultural machinery, machinery tools, machine tools, and other tools and parts in the automotive industry. It is also used to make valves, oil field equipment, and industrial machinery. In addition, it is used for cold punching and forging applications, as well as for making balls, pins, bolts, nuts, and other fasteners.
Conclusion
45Mn2 steel is an alloy steel developed in the 1970s in China. It is a medium carbon steel with relatively high hardness and good strength. It has good cold forming properties and can be welded and hardened. It is composed of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, and molybdenum. This type of steel is used to make parts and tools, as well as agricultural machinery, machinery tools, machine tools, valves, and other equipment.
