Unveiling the Strength of 655M13 Steel Grade: A Comprehensive Overview

655M13 steel is a low-alloy chromium-molybdenum steel grade that offers high strength and toughness with good hardenability. It is commonly used in applications where high tensile strength and good wear resistance are required, such as in the manufacturing of gears, shafts, and other mechanical components.

Mechanical Properties:
– Tensile Strength: 850-1000 MPa
– Yield Strength: 620-820 MPa
– Elongation: 16-20%
– Charpy Impact Strength: 20-40 J

Chemical Composition:
– Carbon (C): 0.12-0.18%
– Manganese (Mn): 0.40-0.70%
– Silicon (Si): 0.10-0.40%
– Chromium (Cr): 0.40-0.60%
– Molybdenum (Mo): 0.20-0.30%
– Phosphorus (P): 0.035% max
– Sulfur (S): 0.035% max

The combination of these mechanical properties and chemical composition makes 655M13 steel suitable for a wide range of industrial applications, especially in components that require high strength, toughness, and wear resistance. Its heat-treatable nature also allows for further improvements in its mechanical properties, making it a versatile and widely used steel grade in the engineering and manufacturing industries.
