Duplex stainless steels are considered resistant to stress corrosion cracking because they are not as resistant to this form of corrosion as ferritic stainless steels.
2507 (UNS S32750) is a super duplex stainless steel designed for applications requiring excellent strength and corrosion resistance.
Duplex steels have the best resistance to pitting corrosion. This steel has effective fatigue strength to resist corrosion of the steel. The steel can be used in a wide range of heating temperatures in the industry.
Duplex steel UNS S31803 round bar is widely used for ferritic and austenitic duplex stainless steel bars.
As a global leader in the supply and distribution of duplex 2205 round steel, our steel is used in oil and gas, hydropower, pressure vessels, pulp and paper, structural components, chemical tankers and many other industrial applications.
Duplex 2205 is the most widely used duplex (ferritic/austenitic) grade of stainless steel. It is used due to its excellent corrosion resistance and high strength.
Duplex 2205 has higher resistance to crevice and erosion corrosion than sus316L austenitic stainless grades.
Duplex Steel S32205 bar stock is a ferritic, duplex, austenitic 3% molybdenum, 22% chromium and 5% – 6% nickel alloy stainless steel.
Duplex steel UNS S31803, UNS S32205 round rods and wires are widely used in chemical, oil and gas, fertilizer and other application industries.
Duplex 2205 round steel contains 22% chromium, 3% molybdenum, and 5-6% nickel. In addition to excellent impact toughness and high strength, it also has high general, local and stress corrosion resistance.
Duplex 1.4462 round bars also have low thermal expansion and high thermal conductivity as well as high corrosion and erosion fatigue properties compared to austenite. The corrosion resistance of duplex 2205 is almost twice that of other austenitic stainless steels.
2205 has good solderability. The motivation for welding dual-phase steels is to maintain the corrosion resistance, toughness and strength of the base metal in the weld metal and heat affected zone.
Duplex steels are also magnetic, a property that can be used to easily distinguish them from ordinary austenitic stainless grades.
We are a manufacturer of Stainless Steel Round Bar, Formed Steel and Rebar, we supply bars such as 304, 304l, 316, 316l and 347. We are proud to have the largest share of stainless steel forming steel in the country.
Another advantage of grade 304 stainless steel bar over grade 303 is that it is slightly harder and has better corrosion resistance. Because of this, grade 304 stainless steel bar is used in large quantities in the manufacture of fasteners and fixtures such as nuts, bolts, washers, clips, fittings and clamps. Products made from grade 304 stainless steel in the fastener industry are often referred to as “A2”.
Duplex-grade stainless steel alloys have ferritic/austenitic properties, giving these materials superior strength and excellent resistance to oxidation.
