Everything You Need to Know About 240M07 Steel Grade

[ad_1] 240M07 is a carbon manganese steel that is commonly used in the production of components such as gears, shafts, and fasteners. It is also known as EN1A in the United Kingdom. This steel grade is known for its high machinability, good weldability, and moderate strength.

Mechanical properties:
– Tensile strength: 370-540 MPa
– Yield strength: 230-400 MPa
– Elongation: 25-28%
– Hardness: 60-80 HRB

Technical properties:
– Density: 7.85 g/cm3
– Young’s modulus: 200 GPa
– Poisson’s ratio: 0.30
– Thermal expansion: 11.0 x 10-6/K

Chemical composition:
– Carbon (C): 0.07-0.15%
– Manganese (Mn): 0.80-1.2%
– Phosphorus (P): 0.04% max
– Sulfur (S): 0.20-0.30%
– Silicon (Si): 0.10-0.40%

These properties make 240M07 steel grade suitable for applications where good machinability and moderate strength are required. It is often used in automotive, construction, and general engineering industries. However, it is important to consult with a materials engineer or steel supplier to determine the best heat treatment and machining practices for this steel grade.
