1.3343 High Speed Steel Bar

Products Description

1.3343 High Speed Steel as the representative of the general steel W-Mo high speed steel. The steel has the advantages of fine and uniform carbide, high toughness and good plasticity.
It contains a variety of alloy elements in high alloy steel, is ledeburite steel. It has high hardness, high wear resistance, high hardness, high hardenability and sufficient plasticity and toughness, and has good casting, forging, welding and machining performance, so it occupies an important position in the tool steel.
