420 Stainless Steel Round Hole Plate Introduction
420 Stainless steel round hole plate is a type of metal made by punching on 420 stainless steel plates to form round hole patterns. Nowadays, the round hole perforation is the most popular perforation pattern.
420 Stainless steel is a martensitic stainless steel with similar corrosion resistance to 410. In addition, it has increased strength and hardness and is magnetic in both hardened and annealed conditions. In order to attain maximum corrosion resistance, 420 stainless steel can be fully hardened and stress relieved.
