Alloy inserts have innovative features
Alloy blade is a much lower cost than stainless steel, but it is because tungsten steel, which is both wear-resistant and hard enough, is not particularly expensive and is more suitable for round blade cutting. Not only is the cost lower than that of those made of stainless steel, but more importantly, the tungsten steel blade keeps the blades stable at high temperatures in rotating contact, also because the price of these tungsten steel materials is not particularly high. And it is easier to process. Now the round insert can be made of tungsten steel and more round inserts with innovative features.
