ASTM5120
Steel with higher hardenability, poorer toughness, and better weldability
ASTM5120 is a steel with high hardenability, poor toughness, and good weldability.
● Characteristics and scope of application
ASTM5120 15Cr steel has higher strength and hardenability, but poor toughness; it has better weldability and generally does not require heat treatment after welding. ASTM5120 is used for carburized parts with high core strength requirements and surface wear, large size, or complex shape but low load, such as gears, gear shafts, cams, piston pins, worms, etc., 5120 lost wax investment Casting can also be used as quenched and tempered parts that work at high speeds and bear moderate impact loads.
● Mechanical properties
Tensile strength σb (MPa): ≥835(85)
Yield strength σs (MPa): ≥540(55)
Elongation δ5 (%): ≥10
Sectional shrinkage ψ (%): ≥40
Impact energy Akv (J): ≥47
Impact toughness value αkv (J/cm2): ≥59(6)
Hardness: ≤179HB
Sample size: The sample blank size is 15mm
● Heat treatment specifications and metallographic structure
Heat treatment specifications: Quenching: 880℃ for the first time, 780~820℃ for the second time, water cooling or oil cooling;
Tempering 200℃, water cooling, air cooling.
● Delivery status
Delivery with heat treatment (normalizing, annealing, or high-temperature tempering) or without heat treatment, the delivery status should be specified in the contract.
