Steel introduction: PM ASP® 2030 Steel

/in /by

The ASP® is a range of powder metallurgy high-speed steel brands form Erasteel, a subsidiary of France Eichmann group. The ASP® steels are suitable for a wide range of tooling and component applications like cutting tools, cold work tools, saws & knives, automotive components and wear-resistant components. The steel mainly includes: ASP®2005, ASP®2017, ASP®2023, ASP®2030, ASP®2052 and ect, they can be good at different applications such as ASP®2055 with cobalt for gear cutting, ASP®2030 for taps and ASP®2005 for the cold work. Today we will introduce ASP® 2030 steel for you, if interested in, please read on.

 

Features

HSS ASP2030 is characterized by good high wear resistance, high compressive strength and high hardness, overall hardening and heat treatment dimensional stability and resistance to reignition, especially suitable for use in high load forming dies and multi-blade tools.

Heat treatment

  • Soft annealing in shield gas in the temperature of 850 ~ 900℃ for 3 hours, then slow cooling 10℃ to 700℃ per hour, followed by air cooling.
  • De-stress is between 600℃ and 700℃ for about 2 hours, then slowly cool to 500℃.
  • Quenching in the shielding gas, preheating at 450 ~ 500℃ and 850 ~ 900℃ respectively, austenitizing at the required hardness suitable temperature, slow cooling to 40 ~ 50℃.
  • It is recommended to temper 3 times at 560℃ for at least 1 hour each time, cool to room temperature (25℃) in the process of tempering.

 

Surface treatment

ASP2030 is a good substrate material for PVD (physical coating) and CVD (chemical coating). If nitriding is required, 2 to 15 m thick permeable layer or steam tempering is recommended.
