nkọwa

M2/1.3343 die 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.


ngwa:

1)Production load large, complex shape and valuable tool (e.g, scraper, gear, milling cutter, drilling, tapping, etc.)

2)Cold forging die, forging tools;

3)Strip cutting machine, heading forming die;

Na-ekpo ọkụ:To minimize distortion and stresses in large or complex tools use a double preheat. Heat at a rate not exceeding 400°F per hour (222°C per hour) to 1100°F (593°C) equalize, then heat to 1450-1550°F (788-843°C). For normal tools, use only the second temperature range as a single preheating treatment.
