Stainless AISI 420 UNS S42000 Cold Rolled Strip Steel, Coil
Martensitic stainless steels are essentially alloys of chromium and sufficient carbon content
that transform into martensite, a distorted body-centered cubic crystal structure, after hardening.
They are magnetic, and are formulated to respond well to heat treatment.
Similar to non-stainless hardenable steels, the maximum attainable hardness, and strength,
is in direct proportion to the amount of carbon present in the alloy.
However, the chromium present in the alloy allows for maximum hardness to be reached in
all but the thickest sections by austenitizing and quenching in air (air-hardening).
Corrosion resistance in mild atmospheric environments is excellent; many times better
than mild steel; however common martensitic stainless steels are not as corrosion-free as highly
alloyed austenitic stainless grades such as 316L in harsh environments.
Martensitic stainless steels are specified when the application requires good tensile strength,
creep, and fatigue strength properties, in combination with moderate corrosion resistance and
heat resistance up to approx. 1200 °F.
Typical (historical) uses of this grade include cutlery, turbine engines, petrochemical equipment,
surgical and dental instruments, scissors, valves, gears, cams and ball bearings.
Depending on the carbon content, martensitic alloys can be capable of tensile strengths approaching
300 ksi (2000 Mpa).
The most common, type 410, can be hardened to approximately 200 ksi (1400 Mpa) in an as quenched-state.
However, a tempering operation is usually performed to increase ductility and reduce brittleness.
Martensitic stainless steels are readily available in coil, sheet, strip, plate, wire and bar forms.
AISI 420 - UNS S42000
AISI Type 420 is a martensitic stainless steel that provides increased strength and hardness
relative to Type 410, with moderate corrosion resistance. It is magnetic in both the annealed
and hardened conditions.
Maximum corrosion resistance is attained in the fully hardened or fully hardened and stress
relieved condition.
High carbon content results in the formation of chromium carbide compounds,
providing excellent wear resistance and edge retention when hardened.
