Description of 2205 Duplex Stainless Steel Sheet:
Alloy 2205 (UNS S32305/S31803) is a duplex stainless steel composed of 22% chromium, 3% molybdenum and 5-6% nickel-nitrogen alloy. It has high strength, good impact toughness and good overall and local strong corrosion resistance.
Compared with 316L and 317L austenitic stainless steel, 2205 alloy is superior in pitting corrosion and crevice corrosion resistance. It has high corrosion resistance. Compared with austenite, it has a lower thermal expansion coefficient and heat conduction Higher sex.
Compared with austenitic stainless steel, its compressive strength is twice that, compared with 316L and 317L, the designer can reduce its weight and its cost is also lower.

Features of 2205 Duplex Stainless Steel Plate
2205 duplex stainless steel is a duplex stainless steel composed of 22% chromium, 3% molybdenum and 5-6% nickel nitrogen. It has high strength, good impact toughness and good overall and local stress corrosion resistance.
Compared with 316L and 317L austenitic stainless steel, 2205 alloy is superior in pitting corrosion and crevice corrosion resistance. It has high corrosion resistance. Compared with austenite, its thermal expansion coefficient is lower and heat conduction. Higher sex.
The yield strength of 2205 is twice that of austenitic stainless steel. This feature enables designers to reduce weight when designing products, giving this alloy a more price advantage than 316 and 317L.
This alloy is particularly suitable for the temperature range of -50°F/+600°F. For applications beyond this temperature range, this alloy can also be considered, but there are some limitations, especially when applied to welded structures.
Product & Application
Common applications of 2205 stainless steel plates: chemistry, desalination, material handling, oil and gas mining, pulp and paper, petrochemicals. Products that are partially or fully constructed of duplex stainless steel include: cargo tanks, couplings, diaphragm seals, fasteners, heat exchangers, hubs, exterior pipes, pipe fittings, pressure rollers, pressure vessels, screw conveyors, shafts , Valve parts.
Other Features:
1) Chemical and Physical characteristic: durable, corrosion resistant and high-temperature resistant
2) We also produce pipes with special specifications according to customers' requirements
