This 4140 steel stamping shaft, also known as 42CrMo4 or 1.7225, is a chromium-molybdenum alloy steel bar designed for heavy-duty stamping, shaft, and roller applications. The material is supplied in a quenched and tempered state, meeting ASTM, JIS, GB, and EN standards. Mechanical properties include a tensile strength of ≥1080 MPa, yield strength of ≥930 MPa, and elongation of 12%, with a hardness of ≤217HB. The chemical composition features carbon at 0.38-0.45%, chromium at 0.90-1.20%, and molybdenum at 0.15-0.25%, ensuring high strength and machinability.
The alloy’s chromium and molybdenum content provides superior toughness and wear resistance, making it suitable for high-stress environments like aviation, automotive, and machinery manufacturing. Typical industry use includes applications where precision and durability are critical, such as hydraulic shafts, gears, and connecting rods. The material is often heat-treated to achieve specific hardness levels, with standard post-processing including annealing, normalizing, or stress relieving to meet engineering tolerances.
Buyers in sectors like petrochemical, electronic information, and transportation source this shaft for its ability to withstand dynamic loads and cyclic stresses. It is available in customized dimensions based on buyer drawings, with common lengths ranging from 1 to 6 meters. The material’s versatility extends to cold-drawn or hot-rolled finishes, depending on the application’s requirements. For bulk orders, confirm the supplier’s ability to meet specific diameter, straightness, and surface finish tolerances.

Before placing an order, verify the supplier’s ability to meet your exact specifications, including diameter, length, and surface finish tolerances. Request a material test report (MTR) to confirm the chemical composition and mechanical properties, as these are critical for high-stress applications. Check if the supplier can provide third-party inspection certificates for quality assurance.
Confirm the logistics details, including packaging, loading port, and Incoterms. For bulk shipments, clarify whether the material will be supplied in bundles or individual pieces, and ensure the packaging meets export standards to prevent damage during transit. Lead times may vary based on customization requirements, so agree on a realistic delivery schedule.
Quality checks should include dimensional verification, hardness testing, and visual inspection for surface defects. For machined components, request a first-article inspection (FAI) report to ensure the parts meet your drawings. Documentation such as the MTR, heat treatment records, and compliance certificates should accompany the shipment for traceability.
