SS 17-4 PH Cold Rolled Coils are cold-rolled coils for a smooth, precise finish with enhanced mechanical properties. Their high strength, excellent dimensional accuracy, and corrosion resistance make them suitable for high-performance applications.
We ensure transparency with our Stainless Steel 17-4 PH Coils as we have the assurance of quality. All shipments are accompanied by necessary documents: a commercial invoice, packing list, fumigation certificate, heat treatment chart, and NABL-approved lab test report. We provide EN 10204/3.1b material test certificate, PMI test certificate, 100% radiography test report, and Third-Party Inspection Certificate. The documentation is thorough and well-structured to ensure total client satisfaction.
17-4 PH stainless steel Industries that require exceptional strength, resistance to corrosion, and dimensional stability frequently use coils. They are utilised for fasteners, structural elements, and turbine blades in the aerospace sector. Because these coils are resistant to seawater conditions, the marine industry uses them in shafts and propeller components. They are used in process equipment, heat exchangers, and reactors in the chemical and petrochemical industries. Other applications include nuclear waste processing, paper mills, and food processing machinery. They are perfect for high-load, high-precision manufacturing settings because of their exceptional mechanical properties and high performance under stress.
