20CrNiMoH Introduction
20CrNiMoH is an alloy steel that is comprised of high chromium and molybdenum contents, along with an expansive element like nickel. This combination of elements provides it with excellent strength and hardness properties, making it ideal for use in components and parts that have demanding structural requirements such as pins, shafts, and sprocket wheels. Additionally, it is highly corrosion resistant, allowing it to perform well in external environments that are wet or contain chemical compounds.
20CrNiMoH Manufacturing Process
20CrNiMoH is typically produced via forging, and is known for its high resistance to shock and wear. The alloy is heated to a higher than normal temperature and is then forced into a desired shape using pressurized or hammer equipment. The shape may include a variety of ideas, from rods, plates, bars, and hollow components. During the forging process, the alloy maintains its strength and hardness levels, as well as its plasticity, which allows it to be machined and formed more easily.
The heating and forging of 20CrNiMoH is conducted in an oxygen-free environment, to ensure the continued strength of the alloy. the entire process is observed and monitored by engineers, who oversee the entire process and ensure that the alloy is prepared to meet the manufacturer’s requirements.
20CrNiMoH Chemical Composition
20CrNiMoH consists of several different metals and elements, including chromium and molybdenum with additional elements such as nickel and phosphorus. The amount and combination of these elements provides the steel its superior strength and durability, along with its corrosion resistance. The chemical composition of 20CrNiMoH is listed below:
• Chromium - 19.0 to 21.0 %
• Molybdenum - 0.90 to 1.15 %
• Nickel - 1.50 to 2.00 %
• Phosphorus - 0.25 %
20CrNiMoH Applications
20CrNiMoH is used primarily in the construction of several different components and welded parts, such as marine rudders, automotive camshafts, and pins for power tools. Many of these components and parts are particularly sensitive and demand great strength, so 20CrNiMoH is an ideal choice. Moreover, due to its superior corrosion resistance, it is commonly used to construct components and parts that are regularly exposed to water and other chemicals.
Conclusion
20CrNiMoH is an alloy steel that combines high chromium and molybdenum content with lower elements like nickel and phosphorus to provide superior strength, hardness, and corrosion resistance. Its most common application is in the construction of parts and components that need these qualities, such as maritime rudders, automotive camshafts, and pins for power tools. The alloy is manufactured via forging, in an oxygen-free environment, and its chemical composition ensures it can withstand corrosion and wear.
