Principal Design Features
|
|
This alloy is a general purpose heat treatable chromium steel which is a popular cutlery grade.
|
|
|
Applications
|
|
Dental and surgical instruments, cutlery, pump shafts, plastic molds and dies, steel balls, and various hand tools.
|
|
|
Machinability
|
|
Similar to machining some of the high carbon tool steel, this alloy has tough, stringy chip build-up.
|
|
|
Welding
|
|
Not commonly welded due to its air hardening characteristics. Welding may be performed after preheating to 300-400 F (149-204 C) with post weld tempering at temperature for 2 hours . Filler metal should be AWS E/ER420.
|
|
|
Hot Working
|
|
Bring temperatures slowly up to 1400 F (760 C), then on to 2000-2200 F (1097-1204 C), after working, furnace cool slowly to avoid cracking. Reheat often to keep the working temperature above 1600 F.
|
|
|
Cold Working
|
|
420 will withstand only minor cold work. Radical forming operations will result in cracking.
|
|
|
Annealing
|
|
1550-1650 F (843-900 C), slow furnace cooling.
|
|
|
Tempering
|
|
300-400 F (149-204 C), air cool for maximum hardness and corrosion resistance.
|
|
|
Hardening
|
|
Soak at 1850-1950 F (1010-1066 C) at quench in heated oil.
