DESCRIPTION
Type 420 is a martensitic stainless steel that provides good corrosion resistance similar to 410 plus increased strength and hardness. It is magnetic in both the annealed and hardened conditions. Maximum corrosion resistance is attained only in the fully hardened condition. It is never used in the annealed condition.

ADDITIONAL PROPERTIES
CORROSION RESISTANCE
Type 420 provides full corrosion resistance only in the hardened or hardened and tempered. In these conditions, its corrosion resistance is similar to type 410. Refer to NACE (National Association of Corrosion Engineers) for recommendations.
FINISHES
# 1 - Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
# 2D - Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process. # 2B - Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.
#BA- Bright annealed cold rolled and bright annealed
#CBA- Course bright annealed cold rolled matte finish and bright anneal
#2 - Cold Rolled
# 2BA- Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part. Polished - Various grit finish for specific polish finished requirements.
* Not all finishes are available in all alloys - Contact Ulbrich Sales for more information.
WIRE FINISHES
XC - Extra clean bright annealed or bright annealed and cold rolled Grease - Ultra-bright finish (for decorative applications) Soap - Soap is not removed from tempered wire to act as a lubricant. * Contact Ulbrich Wire for custom wire finishes.
COLD FORMING
Type 420 can be moderately drawn and formed in the annealed condition.
HEAT TREATMENT
Alloy 420 can be hardened by cold working and by heat treating. Please refer to Ulbrich Technical Services Department for more information. Alloy 420 is capable of being heat treated to a hardness of HRC 51 minimum.
WELDING
The martensitic class of stainless steels has limited weldability due to its hardenability. For best results refer to: SSINA's "Welding of Stainless Steels and Other Joining Methods" .
