Stainless Steels

ASC2250® LDX Plates and Strips

(2101 Duplex) Corrosion Resistant, Lean Duplex Stainless Steel Plate

ASC2250 LDX Plates and Strips offers nearly 3 times the strength of type 316L stainless plate, and has a higher wear resistance.  Typical applications includes stainless brackets, containers, guides, washers,    liners and wear strips.  This hybrid stainless steel plate exhibits equal parts Ferrite and Austenite. Excellent product for use in certain sour service environments over 410 and 416 stainless.

ASC2250 LDX is the newest hybrid of stainless steels offering superior service and performance for maintenance applications.  It combines high chromium, nitrogen, and molybdenum to enhance the corrosion resistance and toughness of the steel.  Typical hardness is 290 BHN.  Typical tensile strength is 94,000 PSI minimum.  Call or email us for a quote.

Key Features

Stress Corrosion Cracking (SCC) Resistance – the duplex grain structure of ASC2250 LDX, with its continuous Ferritic phase means this product is much less sensitive to stress corrosion cracking (Sulfide and Chloride). Austenitic stainless grades, such as 304L and 316L are more susceptible to fracture.

Corrosion Fatigue – resists fatigue failure in corrosive environments due to its unique combination of high strength and resistance to corrosion.

Fatigue Resistance – has been evaluated (pulsating tensile fatigue) at two million cycles with a probability of rupture listed at 50.

Caustic Solution Corrosion – testing in simulated “white liquor” shows less weight loss and superior  corrosion resistance when compared to other common stainless steels.

Pitting Resistance – (PRE 26)

High Strength – up to 3x times the strength of 316L stainless.
