Carbon steel ice skates are generally used by beginners at the entry level, the ice knife of different quality mainly depends on the carbon content, such as spring steel. Although the hardness of ice knives used in the same project reaches the same standard, due to different grades of steel, higher grade steel keeps the service life of ice knife for longer under the same conditions. Under normal circumstances, ice knives made of carbon steel surface hardness is HRC56~64.
Stainless steel ice skates are made by high-grade carbon steel or high-speed tool steel, and generally used by skilled or intermediate enthusiasts, the ice knife with a higher steel grade, it has a strong corrosion resistance performance, and can make skaters improve the frequent jump and rotation. Such ice knife is usually coated with a titanium compound, after grinding the maximum hardness of HRC85, reducing the friction between the ice knife and ice, improve the sliding speed, typical as 14C28N Martenite stainless steel, has excellent edge performance, has very high hardness and good corrosion resistance after cold processing.
Powder alloy (PM) ice skates are generally used by a professional athlete or fever enthusiasts, such as K190, K390 alloy is high-end ice knife steel.
