SAE4150 | AISI 4150 Steel | 50CrMo4 | DIN 1.7228 Alloy Steel Forged Round Bar Alloy Steel Bar
AISI 4150 steel is a high-strength alloy structural steel, which has a higher carbon content than AISI 4140 steel in the Cr-Mo series medium carbon alloy steel.
AISI 4150 steel has high strength and toughness, good hardenability, and no obvious temper brittleness, but has white spot sensitivity during hot working.After normalizing or quenching and tempering, the machinability is good, but the plasticity is low during cold deformation, and the corresponding welding performance is poor.
AISI 4150 steel is suitable for forgings with higher strength or larger section than AISI 4140 steel, such as manufacturing large and medium-sized plastic molds that require certain strength and toughness.

Forged Round Bar AISI 4150 1.7288 Forging
Initial Forging Temperature:1200℃
Final Forging Temperature:800℃
Forging Ratio:above 4:1
Post-Forging Treatment: AISI 4150 Steel should be cooled as slowly as possible in sand after forged.As a white point sensitive steel,the recommended practice is to do hydrogen elimination heat treatment immediately after forging.
Forged Round Bar AISI 4150 1.7288 Application
SAE 4150 has good machinability and hence it is used to make nuts, bolts, gears, shafts, arms, rollers, crankshafts, etc. SAE 4150 is used in the automobile industry, aviation industry, automotive industry, oil and gas industry, etc.
