Even early in 1996, Goodklife company established its R&D department. 12 researchers work here, including 4 senior engineers, 3 intermediate engineers and some professors from famous universities. Until now, we have developed some high alloy tool steel, like G1, G2, G3 and 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 and have been rewarded the national invention patents. The life of blades and knives made of G1 and G2 is 2~3 times longer than normal steel.
