The Ultimate Guide to Understanding 150M19 Steel Grade

[ad_1] “150M19” is a low carbon manganese steel grade that is commonly used in the automotive and engineering industries. It falls under the British Standard BS970, and is similar in composition to AISI 1024 and 1524 steel grades.

Technical Properties:
– Tensile strength: 620-850 MPa
– Yield strength: 440 MPa
– Elongation: 18%
– Hardness: 201 Brinell

Mechanical Properties:
– Good tensile and yield strength
– Good hardness and wear resistance
– Excellent machinability and formability
– Good weldability

Chemical Composition:
– Carbon: 0.18-0.24%
– Manganese: 1.45-1.80%
– Phosphorus: 0.05% max
– Sulfur: 0.05% max

This steel grade is often used for making components such as gears, shafts, axles, and crankshafts due to its good combination of strength, toughness, and wear resistance. It can be heat treated to achieve higher hardness and strength levels. It is also suitable for welding and can be easily machined into various shapes.
