General Properties
The Alloy 420 Stainless Steel Plate is a premium, hardenable martensitic stainless steel bar, evolved from the robust Alloy 410. Like its predecessor, it boasts a chromium content of at least 12%, ensuring dependable corrosion resistance. This enhanced stainless steel variant, enriched with more carbon than Alloy 410, is designed to amplify strength and hardness. Post-annealing, it retains good ductility but is capable of hardening to a formidable minimum Rockwell hardness of 50 HRC, the highest among the 12% chromium grades. While welding Alloy 420 is uncommon due to its hardening traits, it remains a possibility. Martensitic stainless steels, including Alloy 420, are engineered for exceptional hardness, albeit with some trade-offs in other characteristics. Its corrosion resistance, though commendable, doesn't quite match that of standard austenitic grades, and its operational range is somewhat constrained by a reduction in ductility at sub-zero temperatures and a loss of strength when over-tempered at high temperatures. Optimal corrosion resistance is achieved when the alloy is hardened and the surface meticulously ground or polished.
Specifications: UNS S42000.
Applications:
420 stainless steel is a versatile material, ideal for applications demanding top-tier corrosion resistance and hardness. However, it's rarely utilized above 800°F (427°C) due to rapid hardening and diminished corrosion resistance. Common applications of the 420 alloy include:
Knives
Blades
Surgical instruments
Needle valves
Shear blades
Scissors
Hand tools
Corrosion resistance:
Less resistant compared to austenitic grades and 17% chromium ferritic alloys
Displays commendable resistance to atmospheric conditions, foodstuffs, fresh water, and mild acids when hardened
Corrosion resistance diminishes when annealed
Smooth surface finish
Heat resistance:
Not advised for use beyond relevant tempering temperatures due to reduced mechanical properties
Scaling temperature approximates 1202°F (650°C)
Machinability
Tends to form hard, elongated chip buildup
Comparable to machining certain high carbon tool steels
Welding
Typically, welding is avoided due to its air-hardening characteristics
Preheat to 300-400°F before welding
Temper for two hours post-welding
Hot Working
Recommended gradual ramp-up to 1400°F, then 2000-2200°F
Post-furnace work, cool slowly to prevent cracking
Reheating is essential to maintain working temperatures above 1600°F
Cold Working
Suitable only for light cold working
Aggressive forming may induce cracking
Annealing
Anneal at 1550-1650°F (843-900°C)
Allow the furnace to cool slowly
Tempering
Temper between 300-400°F
Air cool to achieve maximum hardness and corrosion resistance
Hardening
Soak at 1850-1950°F, followed by quenching in hot oil
