420 stainless steel strip

What is 420 stainless steel strip ?

AISI Type 420 stainless steel is a martensitic alloy that offers increased strength, hardness and corrosion resistance compared to Type 410. Both the annealed condition and the hardened condition are magnetic. The maximum corrosion resistance can be achieved in either the fully-hardened condition or the fully-hardened and stress relieved conditions. When hardened, the high carbon content leads to the formation of chromium-carbide compounds that provide excellent edge retention and wear resistance. It is not recommended to use the alloy at temperatures above 800degF (42degC), as it will soften and lose its corrosion resistance.
Type 420HC is a higher carbon version that can be used to achieve higher hardness.

420 Stainless Steel Strip Hardness

  • Temperature for subcritical annealing of AISI 420 stainless: 1245-1400 degF, 675-760 degC. Air cooling from the temperature range. The Rockwell hardness for AISI 420 stainless steel is 94-97 HRB.

  • For type 420 steel, the full annealing temperatures are 830-885 degrees Celsius (1525-1625 degrees Fahrenheit), then soak in a bath of water for a few minutes. Then furnace cool down to 790 degrees Celsius (1455 degree Fahrenheit), continue cooling with 15-25 degC/h/27-45 degF/h to 595 degrees C (1100 degF), air cool to room temperature. The Rockwell hardness for type 420 steel is between 86 and 95 HRB.

  • The isothermal annealing temperatures for AISI 420 stainless steel are: heat to 830-885 degrees Celsius (1525-1625 degrees Fahrenheit); hold 2 hours at 705 degrees Celsius (1300 degF), corresponding Rockwell hardness of 95 HRB. It is important to preheat the steel at a subcritical temperature range.
