Manufacturer of Copper Nickel Flanges in India
Due to its outstanding ASTM A193 Grade B6 resistance to corrosion caused by seawater, copper-nickel is also known as cupronickel alloys, which are frequently utilized in maritime applications. A form of a copper alloy called cupronickel, often known as copper-nickel (CuNi), contains nickel and fortifying elements like iron and manganese.
Compared to 90-10 copper-nickel alloy, it is more robust and can withstand more significant flow rates. You can also add other elements that can be added to copper-nickel to improve hardness, corrosion resistance, weldability, strength, and castability. The addition of nickel alloy in copper-nickel flanges increases the strength and corrosion resistance of copper-nickel.
What are Grade B6 bolts per ASTM A193?
For high tensile stainless steel bolts, threaded rods, and other exterior threaded fasteners, there is a material specification known as ASTM A193 Grade B6 produced by Super Duplex Fasteners Manufacturer. The AISI 410 stainless steel bar stock or forging stock used to make ASTM A193 Grade B6 bolts is machined and heat-treated to a minimum tensile strength of 110 ksi.
Applications requiring high tensile strength are met by using ASTM A193 B6 stainless steel bolts. A193 B6 stainless steel studs are produced using ferritic grade AISI 410 stainless steel as a primary material. About 13% of this grade of stainless steel alloy is made of chromium.
Fasteners made of super duplex alloy 2507
Compared to standard duplex and 300 series stainless steel grades, Super Duplex Flanges fasteners have higher mechanical strength, excellent corrosion resistance, and less tendency to pit. They are also known by their corresponding designation, super duplex 2507. Due to their high yield strength, which is twice that of conventional austenitic stainless steel like 304 and 316 stainless steel bolts' annealed yield strength, Duplex 2205 and Super Duplex 2507 stainless steel bolts stand out.
Know about the duplex flange
The Duplex Flanges are primarily used to create pipework systems by joining pumps, pipes, valves, and other pieces of equipment. The SS 316L Flanges grades work pretty well for simply fixed service flange connections; however, they perform slightly less when producing intricate metallic shapes. Fortunately, due to the widespread preference for SS 304L Flanges made of mild steel in non-corrosive applications, the workability of the duplex into complex and circular shapes is less of a concern in structural steel.
Specifications of flanges made of super duplex steel S32750 & S32760
Due to the addition of nitrogen, Super Duplex UNS S32760 Reducing Flanges have a reinforced microstructure, manufacturing thin, light, and cost-effective flanges.
Super duplex stainless steel Alloy 2507 (UNS S32750) has a chromium content of 25%, a molybdenum content of 4%, and a nickel content of 7%. It was created for demanding applications requiring exceptional strength and corrosion resistance, such as chemical processes, petrochemical, and seawater equipment.
The steel has excellent thermal conductivity, a low coefficient of thermal expansion, and exceptional resistance to chloride stress corrosion cracking. Excellent resistance to pitting, crevice, and general corrosion is provided by the high concentrations of chromium, molybdenum, and nitrogen.
