Super Duplex steel Fasteners a widely used product manufactured by Champak Steel & Engg. Co. is a very wide platform. We supply the product by maintaining the best quality to serve the client. We made a very cost-effective product too which can match both the national and international markets. When the applications demand exceptional corrosion resistance and strength these grades of super Duplex stainless steel fasteners are used. They are consisting of nitrogen content, molybdenum, and chromium, which supplies outstanding resistance to crevice corrosion attack a chloride pitting.
Super Duplex Steel Fasteners has a metallurgical microstructure which is consist of a mixture of ferrite and austenite category of steel in a proportion of 50-50 that is equal. Some of the advantages of using these fasteners include its physical and superior mechanical properties such as high yield strength, excellent tensile strength, high impact strength, and excellent corrosion resistance. The Super Duplex Steel Fasteners has a quality to fulfill the high demands urge by the gas, oil and marine industries because of its outstanding physical and mechanical properties. It has a perfect combination of molybdenum and chromium which makes it resistant highly to generalized corrosion.
It is difficult to process this alloy due to the presence of elements of alloy like nickel, nitrogen, chromium, and molybdenum. The Super Duplex Steel Fasteners are exposed to thermal cycle operation like welding in the result of which intermetallic phases by precipitation are formed. The Super Duplex Steel Fasteners are widely demanded in chemical processing, desalination equipment, marine application, oil and gas industry, and the gas scrubbing industry. It has outstanding features of high strength, higher thermal conductivity, fatigue, better workability, good weldability, etc.
To provide the best quality product various tests are performed. The test include is the mechanical test, positive material test, creep test, torsion test, compression test, flexure test, fatigue test, proof load test, axial tensile strength, hardness test, mechanical test, and drop-weight test. Some other test is. Pitting corrosion test, radiographic test, ultrasonic test, flaring test, intergranular corrosion test, chemical analysis, destructive/ non-destructive test, micro/macro test, wedge tensile strength test. Packing is done in the standard forms like individual wrapping with strength film, cores on its pallets, spiral wound paper tubes, cartons and cases, crates, and wooden boxes.
