The 34CrNiMo6 Alloy Steel Bar, also referred to as 34CrNiMo6 Steel or 34CrNiMo6 Alloy Steel Rod, is a high-strength, low-alloy structural steel known for its exceptional toughness, wear resistance, and fatigue strength. Produced under strict international standards (EN 10083-3, DIN, ISO), it comes with material certificates, mill test reports, and third-party inspection options. This alloy bar maintains consistent mechanical properties, high hardenability, and reliable corrosion resistance, ensuring stability under demanding industrial conditions.
Key Features & Advantages
High Strength and Toughness: Ideal for components subjected to heavy loads and impact.
Excellent Fatigue Resistance: Maintains performance under repeated stress.
Good Machinability & Weldability: Suitable for forging, machining, and heat treatment.
Durable Surface Performance: Resists wear, abrasion, and mild corrosion.
International Standard Compliance: Meets EN/DIN/ISO quality and certification requirements.
Applications
34CrNiMo6 Alloy Steel Rod is widely used in industries where high strength and reliability are critical:
Automotive components: crankshafts, gears, axles, and connecting rods
Aerospace: landing gear, shafts, and structural parts
Energy equipment: turbines, wind generator shafts
Heavy machinery and mining equipment: gears, pins, and rollers
Defense and marine applications: high-load shafts and critical components
