Super Duplex 2507 Bolts is super-duplex stainless steel grade. Super Duplex Fasteners is a grade of the austenitic-ferritic stainless steel. Hence it has the structure of both austenitic & ferritic stainless steel. The ferrite content of Super Duplex Screws in a solution annealed and quenched condition is between 35-55%. Applications of stainless steel fasteners such as grade Super Duplex Studs can be found across various industries. For instance, the Super Duplex Nuts and Bolts are used in Flue Gas Scrubbing Equipment, Desalination Equipment, Marine Applications, Chemical process pressure vessels, piping and heat exchangers, Pulp & Paper Mill Equipment, Oil and gas industry equipment as well as the Offshore Oil production and technology.
Super Duplex Stud Bolts such as stainless steel 2507 Duplex is known for its ability to be highly resistant to uniform corrosion when exposed to environments containing organic acids such as formic and acetic acid. These Super Duplex 2507 hex screw are also highly resistant to inorganic acids as well. This holds true, especially if the acidic medium contains chlorides. Since the content of carbon is low in Alloy 2507, the Super Duplex 2507 washers tends to be highly resistant to carbide- related intergranular corrosion. Due to the Ferritic portion present in the duplex or dual microstructure phase of the alloy, Super Duplex Nuts are very resistant to stress related corrosion cracking or SCC in warm chloride containing environments.
Table of Content
The chemical composition of Grade 2507 Stainless Steel Bolts includes 25% chromium, 4% molybdenum, and 7% nickel along with elements like carbon, nitrogen and copper in smaller amounts. Due to high levels of chemical elements like chromium, molybdenum, and nickel, Super Duplex 2507 Fasteners have a high resistance to inorganic acids which could cause chloride stress corrosion cracking. It is also resistant to corrosion against organic acids, viz acetic and formic acid. The content of carbon in the Super Duplex Hex Bolt is very low. The risk of carbide precipitation during heat treatment at the grain boundaries is lowered in the presence of trace amounts of carbon. It is also highly resistant to carbide related inter-granule corrosion.
Super Duplex Nuts and Bolts are known for their high strength, ductility, malleability, resistance to corrosion and pitting. It is also known for its high mechanical strength and good weldability. Although the strength of Saf 2507 Bolts is really good, exposing it to a temperature higher than 570°F or 298 °C is not recommended as the stainless steel loses its toughness. Because Super Duplex Alloy 2507 Bolts has good tensile strength along with a low coefficient of thermal expansion, high thermal conductivity and impact strength, 2507 Stainless Steel Bolts are suitable for a variety of mechanical and structural components.
Through additions of elements such as chromium, nitrogen and molybdenum in the stainless steel alloy of Super Duplex Stud Bolt localized corrosion such as pitting and crevice attack are improved. Due to a high PREN value, Alloy 2507 Super Duplex Hex Bolt has excellent localized pitting resistance. The PREN value of Super Duplex Hex Bolt is about 42, which is one of the highest values. A higher PREN number indicates outstanding resistance to pitting.
Usage of 2507 Super Duplex Fasteners needs to be limited to applications below a temperature of about 600° F. Prolonged exposure of the Super Duplex Bolts and Nuts at elevated temperature can reduce both the toughness as well as the corrosion resistance of alloy 2507.
Grade 2507 Super Duplex Stainless Steel Fasteners possesses excellent mechanical properties. Besides these properties, the Super Duplex Steel Bolts has characteristics such as Low rate of thermal expansion, Good weldability as well as workability. Super Duplex Stainless Steel Fasteners can be welded with the addition of filler metals in the alloy. This grade of stainless steel does not require a pre heat as well as a post heat treatment for welding.
