WebAISI 420 steel (SS420) is very brittle under just hardened conditions and usually must be tempered to achieve useful toughness. The tempering temperature for 420 grade stainless steel after austenitizing: 205-370 °C (400-700 °F). The corresponding tensile strength and Rockwell hardness are 1550-1930 MPa (225-280 ksi) and 48-56 HRC.

Alloy 420 is a hardenable, martensitic stainless steel that is a modification of Alloy 410. Similar to 410, it contains a minimum of 12% chromium, just sufficient enough to give corrosion resistant properties. Alloy 420 has higher carbon content than Alloy 410 which is designed to optimize strength and hardness characteristics. rack kombi escada
