General Properties
Alloy 420 Stainless Steel Plate is an exceptional hardenable martensitic stainless steel bar, derived from the renowned Alloy 410. Just like Alloy 410, it boasts a minimum of 12% chromium, ensuring substantial corrosion resistance. However, the 420 variant surpasses its predecessor with a higher carbon content, designed to significantly enhance both strength and hardness. With remarkable ductility post-annealing, it can be hardened to an impressive Rockwell hardness of 50 HRC, the pinnacle of the 12% chromium grades. While its hardening capabilities make welding uncommon, it remains a possibility. The development of martensitic stainless steels focuses on achieving superior hardness, sometimes at the expense of other attributes. Although its corrosion resistance doesn't match that of typical austenitic grades, the optimal performance is achieved when the metal is hardened, with a meticulously ground or polished surface. Its operational range is limited by the reduction in ductility at sub-zero temperatures and strength loss due to over-tempering at high temperatures.
Specifications: UNS S42000.
Applications:
420 stainless steel is extensively employed in scenarios demanding exceptional corrosion resistance and rigidity. Its usage above 800°F (427°C) is rare due to rapid hardening and diminished corrosion resistance. Key applications include:
Knives
Blades
Surgical instruments
Needle valves
Shear blades
Scissors
Hand tools
Corrosion resistance:
Lower resistance compared to austenitic grades and 17% chromium ferritic alloys
Exhibits good resistance to atmospheric conditions, foods, fresh water, and mild acids when in the hardened state
Resistance is diminished in the annealed state
Surface finish remains smooth
Heat resistance:
Not advised for use beyond relevant tempering temperatures due to reduced mechanical properties
Scaling temperature is approximately 1202°F (650°C)
Machinability
Characterized by hard, elongated chip buildup.
Comparable to machining high carbon tool steels
Welding
Generally avoided due to air hardening characteristics
Preheat to 300-400°F before welding
Temper for 2 hours post-welding
Hot Working
Recommended to slowly ramp up to 1400°F, then proceed to 2000-2200°F
Post-furnace work, cool slowly to prevent cracking
Reheating is necessary to maintain working temperatures above 1600°F.
Cold Working
Suitable for only light cold working.
Aggressive forming risks causing cracks.
Annealing
Anneal at 1550-1650°F (843-900°C)
Allow furnace to cool gradually.
Tempering
Temper at 300-400°F
Air cool to achieve maximum hardness and corrosion resistance.
Hardening
Soak at 1850-1950°F, then quench in hot oil.
