Tools: ASP60 like other high speed steel as thermoplasticforging, machining, grinding, machining, welding andpolishing. But in order to avoid the cold forming process.Grinding and EDM can be well applied to high alloy ASP 60.When grinding, must avoid overheating of local surface,machining can choose tungsten steel or high speed steel cutting tools.

Bending strength:

Bending strength is used to measure the material toughness. Through the different quenching temperature to control the material toughness and hardness.

The bending test specimen for round bar diameter 5mmafter quenching at 560 ℃ tempering for three times, eachholding one hour.

Rmb= the ultimate flexural strength of KN/mm2, ± 10%.

Reb= bending yield strength KN/mm2, ± 5%.

Good toughness

Very good red hardness

Very good abrasion resistance

Application: ASP60 steel is especially suitable for application in a single point cutting tool hardness high requirements on the wear resistance of steel and red. Suchtools, cutting tools, forming cutter knife, cold work tool andcutting tool material for machine processing difficult. The annealed state machine processing properties of ASP 60 is low, if the tool manufacturing permits, ASP 60 will showgood performance in the final tool. For example: end milling cutter, cutter shape is simple but extremely long life or simple cold work tool.

Special performance:

ASP60 steel can achieve very high hardness and red hardness. In addition, the size and shape of the ASP60 and other ASP series steel like hardening process has a goodstability of the advantages. But, regardless of size, all have the same toughness. Machining performance is lower than other high speed steel. Grinding performance is better than other high alloy high speed steel, but slightly inferior thanASP30.
