WOYO 4pcs/lot ZH03 (R5) Curving blade for Ultrasonic cutter L-Shaped Blade Curved

Description

Material: High Speed Steel ( HSS ) (1) HSS is a tool steel displaying high hardness ,high abrasion resistance and high heat resistance. (2) HSS has good technics,good cooperation between strength and toughness. Therefore it is mainly used to manufacture complex thin blade and impact-resistant metal cutting tools, which generate heat in high-speed cutting (about 500 ℃) without losing its temper (hardness) 40HRC. And It’s wear resistance is 2 times higher than the high chromium high-carbon steel in high-speed cutting, and sewing 1.5 times stronger. The disadvantage is the larger difficulty of the heat treatment process and using costly. Package list: 2 * L-Shaped Blade Curved
