NITRONIC 30® UNS S20400

Strip, Coil, Foil & Wire, ASTM A240, ASTM A666

Applications

Coal handling equipment: screens, chute liners, buckets. Well screens, mixing tanks, hose clamps. Mining equipment

Description

Nitronic 30® is a nitrogen-strengthened austenitic stainless steel developed for applications requiring good aqueous corrosion resistance combined with good resistance to abrasive and metal-to-metal wear. Nitronic 30® has annealed mechanical properties which are well above those of typical austenitic grades such as 304.

Additional Properties

Corrosion Resistance

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 for All Alloys - Consult Sales for Applicable Finishes.

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 with special finish requests.

Heat Treatment

Nitronic 30® is non hardenable by heat treatment.
