Product Details

ASTM 4140 Steel Coil Application

AISI 4140 steel round bar is an alloy structural steel with good strength and good comprehensive mechanical properties after heat treatment. It has good manufacturability. Maximum operating temperature is 427°C. It is used to manufacture forgings that require higher strength and larger quenched and tempered sections than 35CrMo steel, and can also be used to manufacture turbine fasteners, high-strength parts, valves, bolts, joints, hydromechanical shafts, couplings, tool bodies, molds , brake shoe, winch shaft, support plate filling block, etc.

4140 Steel Coil Characteristics

1.It is low alloy steel with chromium, molybdenum, and manganese.
2.Great toughness, fatigue strength, abrasion and impact resistance.
3.It is widely be used in the industry due to its excellent versatility and usefulness.
4.The higher carbon content in it, the higher the strength and heat treatment capabilities it is.
5.It can be oil hardened to relatively high hardenability.
