General Properties
The remarkable Alloy 420 Stainless Steel Plate is a hardenable martensitic stainless steel bar derived from Alloy 410. Like its predecessor, it boasts at least 12% chromium, ensuring robust corrosion resistance. However, with added carbon compared to Alloy 410, it achieves enhanced strength and hardness. Post-annealing, it demonstrates excellent ductility but can be hardened to an impressive minimum Rockwell hardness of 50 HRC, the highest among the 12% chromium grades. While typically not welded due to its hardening characteristics, welding remains feasible. Crafted for high hardness, it may trade-off other properties such as corrosion resistance, which is lower than typical austenitic grades. Its operational range is limited by decreased ductility at sub-zero temperatures and reduced strength from over-tempering at high temperatures. Optimal corrosion resistance is attained when the metal is hardened, and the surface is finely ground or polished.
Specifications: UNS S42000.
Applications:
The versatile 420 stainless steel is ideal for uses demanding superior corrosion resistance and hardness, albeit not recommended for temperatures exceeding 800°F (427°C) due to rapid hardening and diminished corrosion resistance. This alloy is perfect for:
Knives
Blades
Surgical instruments
Needle valves
Shear blades
Scissors
Hand tools
Corrosion resistance:
Less resistant than austenitic grades and 17% chromium ferritic alloys
Good resistance to atmospheric conditions, foods, fresh water, and mild acids in the hardened state
Resistance diminishes in the annealed state
Maintains a smooth surface finish
Heat resistance:
Not advisable for use above pertinent tempering temperatures due to reduced mechanical properties
Scaling temperature approximates 1202°F (650°C)
Machinability
Hard, elongated chip buildup observed.
Comparable to machining certain high carbon tool steels
Welding
Welding is generally avoided due to air hardening nature
Preheat to 300-400°F before welding
Temper for 2 hours post-welding
Hot Working
Gradually heat to 1400°F, then to 2000-2200°F for optimal performance
Post-furnace, cool slowly to prevent cracking
Reheating necessary to sustain working temperatures above 1600°F.
Cold Working
Suitable for only light cold working.
Aggressive forming may lead to cracking.
Annealing
Anneal at 1550-1650°F (843-900°C)
Cool the furnace 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.
