2. Material: Alloy steel
3. Heat treatment: Annealing or Quenching/Tempering
4. Transport packaging: Steel Pallet
5. Service: Customization
6. Warranty period: One year
Application
In the field of construction machinery, hydraulic piston rods, transmission shafts, high-strength bolts, and frame connecting rods for excavators, cranes, and loaders are used to adapt to heavy loads and vibration environments
during operations.
In the automotive industry, the half shafts, gear shafts, connecting rods, and steering knuckles of heavy-duty trucks and off-road vehicles, as well as the chassis structural components and motor drive shafts of new energy vehicles, meet the requirements of fatigue resistance and stability.
In the field of mechanical manufacturing: machine tool spindles, gears, worm gears, couplings, transmission rods for automated production lines, load-bearing components for press machines, suitable for high-frequency and high load working conditions.
In the field of petrochemicals, drill pipe joints, salvage tools, and wellhead equipment connectors for oil wells below 2000 meters are designed to withstand high pressure and corrosive environments underground.
Aerospace field: aircraft engine auxiliary components, landing gear connecting parts, fuselage structural reinforcement parts (mostly precision machined), balancing lightweight and high-strength requirements.
In the military industry: artillery locking components, tracked equipment transmission components, weapon supports, suitable for strengt
h and reliability requirements under complex working conditions.Feature
1.42CrMo4 is a medium carbon alloy structural steel with high strength, high hardenability, and good toughness
2. Mechanical properties: Tensile strength (σ b) ≥ 1080MPa, yield strength (σ s) ≥ 930MPa, elongation (δ 5) ≥ 12%, section shrinkage rate (ψ) ≥ 45%, impact toughness (Akv) ≥ 63J, hardness in annealed state ≤ 217HB, can be improved to HRC48-52 after heat treatment.
3. Heat treatment process: The quenching temperature range is between 820 ° C and 860 ° C, followed by rapid cooling in oil or water; The tempering temperature depends on the required hardness, usually between 540 ° C and 680 ° C, followed by air cooling. By quenching and tempering, the mechanical properties of 42CrMo4 can be significantly improved, including increasing its strength, toughness, and wear resistance.
