Description
Our 42CrMo Steel Forging Blanks – High Load, Stress Relieved Forged Parts are specifically designed for the manufacturing of hydraulic cylinder components operating under high pressure and repetitive motion. Produced using high-quality carbon or alloy steel, each blank is forged to ensure excellent structural integrity and optimized grain flow for improved fatigue resistance.

Key Features:

  • Material Options: 42CrMo, 45#, 35#, or other customized grades

  • Stress-Relief Treatment: Minimizes internal stress for enhanced dimensional stability during final machining

  • Rough Machining: Pre-machined surfaces (inner/outer diameter, end faces) reduce customer processing time

  • High Structural Integrity: Forging process eliminates internal voids and enhances load-bearing capacity

Applications:

    • Hydraulic cylinder barrels, end caps, and rod guides

    • Suitable for use in construction machinery, mining equipment, industrial presses, and marine hydraulics

    • Designed to handle high-pressure environments, axial loads, and dynamic movement cycles

Item Details
Product Name 42CrMo Steel Forging Blanks – High Load, Stress Relieved Forged Parts
Material Grades - High-strength carbon steels: 35#, 45#, customized grades available - Excellent tensile strength, impact toughness, and fatigue resistance - Designed for thick-walled or bored hydraulic cylinder components under cyclic pressure
Forging Equipment - Hydraulic hammers: 5T / 8T / 12T - Large open-die forging press with optional axial core boring - Supports near-net shape forging of cylinder barrels and end closures
Manufacturing Process Hot Forging → Intermediate Heat Treatment → Optional Core Boring / Drilling → Rough Machining → UT & Dimensional Inspection
Forging Ratio ≥ 3.0 — Enhances grain flow along cylinder axis, improving fatigue resistance and sealing surface stability
Applications - Cylinder barrels, end caps, glands, and rod guides for hydraulic systems - Used in construction machinery, presses, marine hydraulics, and mining equipment - Suitable for high-pressure, heavy-load, and repeated motion conditions
Heat Treatment Options - Tempered for high strength and internal hardness - Stress relief applied after forging to reduce residual stress before final machining
Testing & Inspection - Chemical: Spectrometer-controlled composition analysis - Mechanical: Hardness, tensile, yield, impact toughness - Ultrasonic (UT): Multi-angle flaw detection, focused on critical bore and seal areas - Dimensional: Outer/inner diameter, length, wall thickness, concentricity, and straightness
Value-Added Services - Customized bore diameter, wall profile, and external features - Rough-machined ends, grooves, or counterbores ready for final machining - Anti-rust coating, protective caps, steel banding, and export crate packaging - Laser part marking, OEM branding, and full traceability documentation
