2507 hot rolled stainless steel coil

2507 hot rolled stainless steel coil

This 2507 stainless steel combines the characteristics of austenitic and ferritic stainless steels. Compared with ferrite, it has higher plasticity and toughness, no brittleness at room temperature, significantly improved resistance to intergranular corrosion and welding performance, and at the same time retains iron.

Simple description about Duplex 2205 Stainless Steel/Super Duplex 2507 Stainless Steel

Duplex Stainless Steel (DSS) refers to approximately 50% of ferrite and austenite and generally contains less than 30% of stainless steel. In the case of lower C content, the Cr content is 18% to 28%, and the Ni content is 3% to 10%. Some steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N.

This 2507 super duplex stainless steel combines the characteristics of austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no brittleness at room temperature, significantly improved resistance to intergranular corrosion and welding performance, and at the same time retains iron. The 475°C brittleness and high thermal conductivity of the ferritic stainless steel make it superplastic.

Compared with austenitic stainless steels, they have high strength and resistance to intergranular corrosion and chloride stress corrosion resistance. Duplex 2507 stainless steel has excellent pitting corrosion resistance and is also nickel-saving stainless steel.

It has high thermal conductivity and low thermal expansion rate and can be used in heat exchangers and water heaters, but long-term exposure to temperatures close to or exceeding 600°F will result in a decrease in strength.

Finally, 2507 stainless steel is stronger than more nickel based alloys and can use less material to accomplish similar tasks, saving cost and weight. It is also easier to machine and weld than pure austenitic alloys.

Duplex stainless steel classification

The first type is a low-alloy type, which stands for UNS S32304 (23Cr-4Ni-0.1N). The steel does not contain molybdenum and its PREN value is 24-25. It can be used instead of AISI304 or 316 in terms of stress corrosion resistance.

The second type of alloy is a type of alloy, represented by UNS S31803 (22Cr-5Ni-3Mo-0.15N) with a PREN value of 32-33, and its corrosion resistance is between AISI 316L and 6% Mo+N austenitic stainless steel. between.

The third category is a high alloy type, generally containing 25% Cr, also containing molybdenum and nitrogen, and some also contain copper and tungsten, standard grade UNSS32550 (25Cr-6Ni-3Mo-2Cu-0.2N), PREN value is 38-39 The corrosion resistance of this type of steel is higher than that of 22% Cr duplex stainless steel.

The fourth type is a super duplex stainless steel type, containing high molybdenum and nitrogen, standard grade UNS S32750 (25Cr-7Ni-3.7Mo-0.3N), some also containing tungsten and copper, PREN value greater than 40, can be applied to harsh Medium conditions, with good corrosion and mechanical properties, comparable to super austenitic stainless steels.
