Piyush Steel is a leading manufacturer and exporter of the excellent quality of Stainless steel 904L Flanges. These flanges are developed by using the standards quality of raw materials to ensure high quality and durability. The material for SS flanges is under ASME designation like SA105, SA266, etc. Additionally, there are many other industry standards that are referred to as WNR 1.4539 that might be used in some cases on ASME work. These flanges are also known as UNS N08904. To all the buyers we are providing the flanges in standards specifications that vary in dimensions, standards, pressure ratings, sizes, and face types. On the demand of buyers, these flanges are provided to them in customized specifications.
Table Of Content
Because of many good features that are found in the Stainless steel 904L Flanges, the demand and use have become high among the industrialists. These flanges possess many good features like-
• Resistance to stress corrosion cracking
• Pitting and oxidation resistance
• Holds high temperature
• Holds heavyweight
• Rugged construction
• Greater general corrosion resistance
• Accuracy in dimensions
• Smoothness in surface finishes
904L is the austenitic stainless steel. The molybdenum addition provides its superior resistance to localized attacks that includes crevice corrosion and pitting by chlorides and greater resistance to reducing acids. Additions of copper alloy provide corrosion resistance to various concentrations of the sulfuric acid. The high alloy content also provides it high resistance to chloride stress corrosion cracking but the alloy is susceptible. The low carbon content is making it greatly resistant to sensitization through welding that prevents intergranular corrosion. It is thus used in many industrial applications like heat exchangers, pollution control, etc.
Manufacturing of the flanges-
There at our highly operational industry, the manufacturing process of Stainless steel 904L Flanges starts by using the purest quality of raw materials. The raw substances that we are using for the fabrication of flanges are well tested to assure that no poor quality of production is executed of flanges. The manufacturing begins under the strict guidance of professional experts in compliance with the proper use of available modern machinery and latest technology. The quality control team is hired that are looking at the product quality maintenance so that no bad quality of flanges is manufactured and supplied. The designing and fabrication of flanges are done by considering raw material quality standards and production guidelines.
Testing of the flanges-
Before the Stainless steel 904L Flanges are packed are dispatched to the respected buyers, its testing is conducted properly. The tests are done with the clear motive of checking how good the quality of flanges that are produced is. Testing conducted is namely-
• Positive material identification test
• Hardness test
• Flattening test
• Flaring test
• Intergranular corrosion test
• Chemical test
• Mechanical test
• Pitting resistance test
• Micro test
• Macro test
The test certifications are also provided by us in order to prove that no Stainless steel 904L Flanges are provided that could be filled up of impure elements. To proves the purity of flanges we are providing TC like-
• Mill test certifications in accordance with EN 10204/3.1b
• 100% radiography test report
• Buyers report
• Third party Inspection report
• Raw material certificate
Documents offered -
We too are providing essential documents to our buyers just to give them a surety that full fairness is maintained in dealing and excel the quality of flanges are provided. Documents like QAP, heat treatment chart, packaging list, guarantee letter, material traceability report, NABL approved lab test report, etc are provided to the buyers.
