 Super Duplex Stainless Steel S32750 / S32760 Wire Mesh, which can readily be used down to at least -50 Degree C. Super Duplex S32750 Hexagonal Wire Mesh is extremely corrosion resistant, work hardenable alloys, where their microstructures consist of a mixture of austenite and ferrite phases. As a result, Super Duplex S32760 Welding Wire Mesh display properties characteristic of both austenitic and ferritic stainless steels. Combination of austenitic and ferritic properties in Super Duplex S32750 Netting Wire Mesh can mean some compromise when compared with pure austenitic and pure ferritic grades. Super Duplex S32760 Woven Wire Mesh is in most cases, tougher than ferritic stainless steels, where tooling and work surfaces must be thoroughly cleaned before use. Strengths of Super Duplex S32750 Spring Steel Wire Mesh can in some cases be double that for austenitic stainless steels. Whilst Super Duplex S32760 Fencing Wire Mesh is considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steels. However, the corrosion resistance of the least resistant Super Duplex S32750 Wire Mesh is greater than that for the most commonly used grades of stainless steels, i.e. Type 304 and Type 316. Super Duplex S32750 Wire Mesh are also magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless.

• Stainless ferritic-austenitic Cr-Ni-Mo steel with nitrogen addition.
• High corrosion resistance, especially against stress corrosion cracking in solutions containing chloride.
• Good strength properties.
• Resistant to intergranular corrosion in the temperature range up to 300°C.
• Heat treatment subsequent to welding not necessary.
• The surface condition for optimum corrosion resistance: pickled, heat treated free from scale or machined.

• Components in the chemical industry, e.g. separator and heat exchanger parts, from the paper industry, oil and gas production, compressor parts, seawater desalination plants.

• Good weldability. Welding is possible with all processes usual for stainless steels. We recommend depending on applications electric arc welding with covered electrodes, inert gas welding or SA-welding. Preheating and heat treatment after welding is not necessary. For high stressed heavy walled constructions, the limited preheat temperature of 150°C maximum is recommendable. Maximum interpass temperature 150°C. Keep heat input low especially for small wall thicknesses. The TIG-process should be given a reference for root welding.

• Pressure vessels, tanks, piping, and heat exchangers in the chemical processing industry
• Piping, tubing, and heat exchangers for the handling of gas and oil
• Effluent scrubbing systems
• Pulp and paper industry digesters, bleaching equipment, and stock-handling systems
• Rotors, fans, shafts, and press rolls requiring combined strength and corrosion resistance
• Cargo tanks for ships and trucks
• Food processing equipment
• Biofuels plants

• Machine manufacturing units
• Dairy and food processing industry
• Furniture
• Tools industry

Super Duplex Steel S32760 Round Bars has outstanding corrosion resistance to an extensive range of media, by means of exceptional resistance to crevice corrosion and pitting in seawater and other chloride comprising atmospheres, through Critical Pitting Temperature beyond 50 Deg C. Super Duplex S32750 Round Bars is steel industrialized for uses that demand corrosion resistance and high strength. Super Duplex Steel S32750 Square Bars merges the most necessary features of both austenitic and ferritic steels. Meanwhile, these Super Duplex Steel S32760 Flat Bars are also being offered in different sizes and shapes to our customers. Immediately below certain range, the austenite Super Duplex Steel S32750 Threaded Bars becomes substantially stronger than the ferrite and may cause cracking, a particular danger to “cold” edges. Super Duplex Steel S32760 Hollow Bars has high strength and high corrosion resistance to produce high corrosion fatigue strength. Below 1700 Degree F, there can be rapid formation of intermetallic phases in these Super Duplex Steel S32750 Hexagonal Bars because of the combination of temperature and deformation. In this test, uniaxial loaded Super Duplex Steel S32760 Triangular Bars mill – annealed specimens have withstood 500 hours without cracking at an applied stress.
