Understanding the Properties and Uses of 820A16 Steel Grade

820A16 is a low carbon steel grade with good mechanical properties and moderate wear resistance. It is commonly used in applications where high strength and hardness are required, such as in the manufacturing of gears, shafts, and other machine components.

Mechanical Properties:
– Tensile Strength: 620-850 MPa
– Yield Strength: 480 MPa
– Elongation: 12%
– Hardness: 200-250 Brinell (HB)

Chemical Composition:
– Carbon: 0.17-0.22%
– Silicon: 0.15-0.35%
– Manganese: 0.70-1.00%
– Phosphorus: 0.035% max
– Sulfur: 0.040% max
– Chromium: 0.40-0.60%
– Molybdenum: 0.20-0.30%

The specific properties and composition of 820A16 steel make it suitable for use in a variety of industrial applications, particularly in the production of heavy-duty machinery and equipment. Its moderate wear resistance and high strength make it a popular choice for components that are subject to high stress and mechanical wear.
