Low Price AISI SAE3415 Hot Rolled Alloy Rod Diameter 33mm Die Steel Round Rods 12CrNi3 Stainless Steel Bar for Machinery
1, Chemical composition
SAE3415 is a low-carbon nickel chromium alloy structural steel with a chemical composition design that balances strength and toughness. The specific range is as follows:
Elemental carbon (C), silicon (Si), manganese (Mn), chromium (Cr), nickel (Ni), phosphorus (P), sulfur (S)
Content: 0.14-0.20% ≤ 0.40% 0.40-0.70% 0.60-1.00% 3.00-3.50% ≤ 0.035% ≤ 0.035%
2, Mechanical properties
Performance indicator numerical range
Tensile strength (σ b) ≥ 930 MPa (higher after quenching and tempering)
Yield strength (σ s) ≥ 685 MPa
Elongation rate (δ 5) ≥ 11%
Sectional shrinkage rate (ψ) ≥ 50%
3, Core Features
Balance between high strength and toughness
Scientific proportioning of carbon and nickel elements enhances tensile strength (≥ 930 MPa) and cross-sectional shrinkage rate (≥ 50%), suitable for high load components;
Nickel element optimizes low-temperature toughness and adapts to extreme working conditions of aerospace and energy equipment.
Wear resistance and corrosion resistance
Chromium element enhances surface hardness, significantly improves wear resistance after carburizing, and prolongs the service life of components such as gears and crankshafts;
Excellent oxidation and corrosion resistance, suitable for high-temperature petrochemical pipelines and nuclear power valves.
Process adaptability
Good hardenability, supporting uniform hardening of large section parts (such as heavy-duty gear shafts);
Easy to forge and cut, suitable for the forming requirements of complex mechanical parts.
4, Typical applications
Automotive industry: crankshafts, connecting rods, gearbox gears (high dynamic load and friction scenarios);
Aerospace: engine turbine shaft, high-temperature load-bearing structural components;
Heavy machinery: mining equipment gears, hydraulic system high-pressure connecting rods;
Energy equipment: nuclear power plant valves, petrochemical high-temperature pipeline connectors.
5, Quality Inspection and Process Control
Defect detection: It is necessary to verify the internal uniformity of the material through ultrasonic testing to avoid cracks or inclusions;
Performance verification: Hardness gradient testing (surface and core) and tensile testing are used to ensure that the mechanical properties meet the standards.
SAE3415 has become the preferred material for key components in the aerospace, energy equipment, and heavy machinery fields due to its high strength, excellent wear resistance, and process adaptability
