High-Precision Tungsten Steel Valve Stem with YG10X

Product Description

High-Precision Tungsten Steel Valve Stem with YG10X

Product Overview

Our tungsten steel valve stem is manufactured from premium YG10X carbide material through precision machining processes, designed for demanding industrial environments. This valve stem achieves industry-leading standards in coaxiality (≤0.002mm) and cylindricity (≤0.002mm), with the spherical head's profile tolerance controlled within 0.005mm, ensuring reliability and long service life in high-pressure, high-wear operating conditions.

Material Characteristics: YG10X Carbide

YG10X is an ultra-fine grain tungsten carbide-cobalt hard alloy with the following outstanding properties:

• Exceptional Hardness: HRA≥92.5, significantly higher than ordinary alloy steel
• Superior Wear Resistance: Wear coefficient only 1/15 that of high-speed steel
• High Flexural Strength: ≥2200MPa, ensuring structural integrity
• Corrosion Resistance: Excellent stability against most chemical media
• Thermal Stability: Maintains good mechanical properties at temperatures up to 600°C

The ultra-fine grain structure (grain size 0.4-0.6μm) gives YG10X both high hardness and good toughness, making it particularly suitable for precision components requiring dimensional stability.

Specifications

Quality Assurance System

We implement strict quality control throughout the entire process:

1. Incoming Inspection: Composition analysis and physical property testing of YG10X material
2. In-Process Inspection: Key dimension checkpoints at each manufacturing stage
3. Final Inspection:
• Coordinate measuring machine (accuracy 0.5μm)
• Roundness tester for cylindricity measurement
• Optical profile projector for contour comparison
4. Batch Traceability: Each product has an independent quality record
