High Speed Steel 3243

Main Characteristic

3243 is in the group of High Speed Tool steel which can stand for high temperature
and maintain its strength at any temp. It's properties in the sense is much better when
compare to 3343. Thanks to its cobalt content which help maintain its cutting edge
and can last for any condition of usage. Suitable for cutting task that need to cut through
high strength materials in a condition of high temp or high abrasive in long period

OutStanding Properties
