STAINLESS STEEL
420
420 is essentially type 410 with higher carbon, and like 410, it is a 12% chromium stainless steel. After heat treatment, because of its higher carbon levels, 420 can achieve higher strength and hardness levels than 410. This results in better wear resistance and edge retention properties.
