M30 Tungsten Carbide Bar Introduction

M30 tungsten carbide bar hardness of not less than 91.5HRA, density is about 14.5g / cm³. Mainly by a mix of tungsten carbide and cobalt powder metallurgy method by milling, ball milling, pressing, sintering, has good wear resistance and flexural strength. Flexural strength of not less than 2200N / mm², including the amount of 78% tungsten carbide ~ 94% plus or minus, cobalt content is 5-11%, plus or minus, the amount of titanium containing between 2% and 10%, containing tantalum amount ranging from 0% to 10%. The main components of tungsten carbide and cobalt alloys, different uses ingredients of tungsten carbide long and cobalt are not consistent, the use of a very wide range. Alloy strip is one of a number of materials, predominantly in a stripe shape. 

Specific material should be used to select the appropriate item according to use carbide, M30 tungsten carbide bar strip nonporous no blisters. Features a high impact toughness and fatigue strength, because it has a high hardness, good weldability, high hardness, high wear resistance characteristics.
