Introduction

Analysis of Standard Technological Innovation

Revision Background and Development History

Against the industrial background of accelerated development of cemented carbide circular economy, GB/T26055 standard has undergone its first major revision since its initial release in 2010. The 2022 version focuses on solving the following industry pain points:

Technical gaps in the comprehensive processing of recycled raw materials
Decomposing the machine tool industry's demand for fine particle size of tungsten carbide materials
Strengthening the standardization requirements for precise control of trace elements

Key points for core parameter optimization

Technical indicators	2010 version	2022 version	Optimization range
Grade system	4 grades	Added WCH5, a total of 5 grades	Classification accuracy increased by 25%
Fisherman particle size (μm)	Not specified	≤700nm	Filling the gap in ultra-fine standards

Quality control technology innovation

Element precision control system

Establish system control requirements for difficult-to-control synergistic elements:

Indicator dimension	Qualified standard
Ta/Nb sum	≤0.03%
Critical oxygen content	<0.25%

Morphological three-dimensional control

Powder chromaticity uniformity
Particle shape irregularity<30% of the honey snow narration observation system generation
Flow characteristic method to detect moisture
