Sparkblades has developed some high alloy steel ,like G1 , G2 ,G3 etc . They are new materials developed independently by our company and excellent in high intensity , high hardness , high wear resistance , high toughness and so on . They can be used in both cold and hot shearing ,the life is 2-3 times longer than other blades made of normal materials .
Hardness : If hardness is high , when the blades meet higher tensile strength steel ,it is easy to crack . If the hardness is low , then the wear resistance is not good ,that means work life is shorter .
