Frequently Asked Questions
What raw materials are utilized in the manufacturing of these carbide grades?
All products are fabricated using 100% virgin tungsten carbide and cobalt powders, ensuring optimal structural integrity, uniform density, and prolonged tool service life without recycled impurities.
How does cobalt content influence the performance of YG carbide grades?
Lower cobalt content (e.g., YG3 at 3% Co) delivers higher hardness and superior wear resistance for finishing tasks. Higher cobalt content (e.g., YG20 and YG30 at 20%–30% Co) increases impact toughness and bending strength, which is essential for heavy stamping and forging.
Which carbide grade is best for fine finishing chilled cast iron and heat-resistant alloys?
YG6X (K10) is specifically optimized for fine finishing chilled hard alloy cast iron and heat-resistant alloy steels due to its fine-grain structure, high hardness (≥ 92 HRA), and balanced wear resistance.
Which grades should be selected for high-stress stamping and cold-heading dies?
YG15, YG20, and YG30 are recommended for stamping dies, steel tube perforating tools, and high-compression components because their bending strength reaches up to ≥ 2500 N/mm² to withstand severe mechanical impacts.
Can material grades be tailored to specific industrial requirements?
Yes, multiple material grades and tailor-made formulations can be produced depending on specific operating conditions, workpiece hardness, and machining methods.
What surface finish and tolerances can be achieved through your grinding process?
Through precision ground and high polishing processes, parts achieve high dimensional accuracy, uniform edge quality, and smooth surface finishes suitable for critical mechanical components.
