Description of AISI 4150 Alloy Steel Round Bar

SAE or AISI 4150 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. This tough steel alloy performs good strength, wear resistance, and great hardness. That means it must be heat-treated to be suitable for machining. It has high weldability and can be achieved through most commercial methods. Now AISI 4150 has been used in the aerospace, defense, oil and gas, and automotive industries.
