Piyush steel today has become one of the most popular industries that are widely appreciated for delivering the commendable quality of industrial products. We are the manufacturer, supplier and exporter of the high quality of Copper Nickel 70/30 (C71500) fasteners. All our offered ranges of fasteners are high in demand today because of the many good features it has to offer. We are providing the product ranges to the buyers in different specifications that are varying differently in standards, sizes, types, length, etc. It is too made available to the national and international buyers at custom-made specifications according to the exact demands buyers are having.
Table Of Content
Copper Nickel 70/30 (C71500) is the alloy that is having the copper of 70% and nickel of 30% with the addition of alloying elements like manganese and iron. These additions are making it somewhat corrosion as well as erosion resistant along with little bit improved strength than other alloys, making it an ideal choice for various applications. The corrosion resistant is well improved notably in the greater velocity water to 4.5m/s and in the polluted seawater. This alloy welded, cold worked and fabricated readily with any need of the special materials. The popular specification that is covering the alloy is C75100 and CN 107 designations. Copper Nickel 70/30 (C71500) fasteners are having high strength, working ability and weldability and this making it weldable or machinable readily with all types of conventional operation. Also, it is having the ability to effectively resist stress corrosion cracking, crevice corrosion, pitting, oxidation, and general corrosion. This fastener is also resisting high heat and high pressure. Moreover, it is having an anti-corrosive body, long-lastingness, greater durability, etc.
Development of the fasteners-
The manufacturing process of Copper Nickel 70/30 (C71500) fasteners are done under the supervision of professional experts with the use of high tech machines and sophisticated technology. This thus reduced the chances of manufacturing of the low quality of fasteners. During the time of development of these fasteners, we are making the effective use of superior quality of alloy that is collected from the reliable market mills and are well tested and quality approved. The availability of quality checker team has also helped us to deliver the commendable quality of fasteners. They are checking the quality of the fasteners based on a few quality checking norms. Whole range of fasteners that we are providing to the buyers is designed according to the set manufacturing norm and product quality standards.
Testing of the fasteners-
The testing of the manufactured ranges of fasteners is done at our manufacturing industry for the purpose of evaluating the quality of those. The produced ranges of fasteners are processed from various kinds of tests that attach to all production lines. The tests done are including chemical test, intergranular corrosion test, axial tensile test, positive material identification test, radiography test, proof load test, drop weight test. Also, more test like pitting resistance test, creep test, ultrasonic test, fatigue test is done on it.
Documenting of the product-
When the ordered ranges of Copper Nickel 70/30 (C71500) fasteners are ready for the shipment of it, we mandatorily consider providing the copies of all essential documents. The test certifications that we are providing is mill test certifications as per En 10204/3.1b, 100% radiography test report, third-party test report, raw material certificate, and buyers test report. Also, we are providing the copies of all essential documents to the buyers like heat treatment chart, quality assurance plan, material traceability report, guarantee letter, packaging list, NABL approved lab testing report, commercial invoice and fumigation certificate. All these help us in proving that we are always delivering the superior quality of product to the buyers.
