Product DescriptionProduct DescriptionTotem Customized 38CrNi3MoVA Large-Diameter Flange Shaft with Corrosion-Resistant CoatingThe Totem Customized 38CrNi3MoVA Large-Diameter Flange Shaft is a high-performance engineered component designed for demanding industrial applications. Crafted from premium 38CrNi3MoVA alloy steel, this flange shaft offers exceptional strength, toughness, and fatigue resistance, making it ideal for heavy-duty machinery, power transmission systems, and critical rotating equipment.Key Features:Material Excellence: Manufactured from 38CrNi3MoVA, a high-strength, low-alloy steel known for its superior mechanical properties and durability under high-stress conditions.Large-Diameter Design: Engineered to meet the needs of heavy industrial applications, ensuring reliable performance in high-torque and high-load environments.Corrosion-Resistant Coating: Enhanced with a specialized anti-corrosion coating to prolong service life, even in harsh or corrosive environments (e.g., marine, chemical, or offshore applications).Precision Customization: Totem offers tailored solutions, including custom dimensions, tolerances, and flange configurations, to perfectly match your operational requirements.Rigorous Quality Control: Each shaft undergoes stringent testing to ensure compliance with international standards for dimensional accuracy, hardness, and structural integrity.Technical SpecificationsHeat Treatment Process of 38CrNi3MoVA Large-Diameter Flange ShaftKey Heat Treatment Stages:Key Heat Treatment Stages:Normalizing (Pre-Treatment)The shaft is heated to 880–920°C, held for sufficient time to achieve uniform austenitization, and then air-cooled.Purpose: Refines the grain structure, eliminates internal stresses from forging, and improves machinability before final heat treatment.Quenching (Hardening)The shaft is heated to 830–860°C (austenitizing temperature), soaked to ensure temperature uniformity, and then quenched in oil or polymer to achieve high hardness.Cooling Rate: Controlled to avoid excessive distortion or cracking, critical for large-diameter components.Tempering (Stress Relief & Toughness Enhancement)After quenching, the shaft is tempered at 550–650°C (depending on required hardness and toughness), followed by air cooling.Effect: Balances hardness and ductility, reduces brittleness, and improves impact resistance.Typical hardness range after tempering: HRC 28–35 (adjustable based on application needs).Optional Secondary Tempering (For Critical Applications)A second tempering cycle may be applied to further stabilize the microstructure and eliminate residual stresses, ensuring dimensional stability in large shafts.Packaging & ShippingDrawings & DimensionsDetailed CAD drawings and dimensional diagrams are available for download here or upon inquiry.
