    CNC machining
Grade 420 stainless steel is a martensitic alloy that exhibits good corrosion resistance, strength, and hardness. Similar to other stainless steel grades, it can be hardened through heat treatment. Both its annealed and hardened forms exhibit magnetic properties. When polished, ground, or hardened, this metal achieves exceptional corrosion resistance properties.
