420U6 cold rolled stainless steel sheet
420U6 is a specific grade of martensitic stainless steel, known for its high hardness and good corrosion resistance. Here are some details about 420U6 stainless steel, particularly in the context of a cold rolled sheet:
High strength
High corrosion resistance

420U6 stainless steel is used in applications requiring high hardness and moderate corrosion resistance, such as:
Cutlery: Knife blades, surgical instruments.
Tools: Cutting tools, chisels, and hand tools.
Industrial: Pump shafts, valves, and other components exposed to mild corrosive environments.
Cold rolling involves passing the steel through rollers at a temperature below its recrystallization temperature, resulting in increased strength and improved surface finish. Cold rolled 420U6 sheets would have:
Higher Strength: Due to the work hardening effect.
Improved Surface Finish: Smoother and more uniform surface.
Tighter Tolerances: Better dimensional accuracy.
420U6 can be hardened by heat treatment. The typical heat treatment process includes:
Annealing: Heat to 840-900°C, then cool slowly to relieve stresses.
Hardening: Heat to 950-1050°C, then quench in air or oil.
Tempering: Heat to 150-370°C, then cool in air. The exact temperature depends on the desired balance between hardness and toughness.
