Table Of Content
Stainless steel 904L alloy is the super austenitic SS that is developed for the average to the high corrosion resistance at the wider ranges of processing atmosphere. The combination of alloying elements like nickel, chromium, copper, and molybdenum is assuring excellent resistance to corrosion. With the highly alloyed chemistry, 4.5% of molybdenum and 25% of nickel alloy, chloride stress corrosion cracking and pitting and general corrosion resistance becomes possible.
Alloy 904L is developed for withstanding the atmosphere that is containing the diluted sulfuric acid. It is also offering resistance ability to inorganic acid like hot phosphoric and organic acid as well. The alloy with the help of standard shop fabrication process can be welded easily.
Development of the product-
The designing and development of Stainless Steel 1.4539 Welded Tubing begin by effectively using the superior quality of raw materials that are well tested and approved by the quality checker. This thus adds greater strength to the product that is produced. The manufacturing of tubes is done under the strict guidance of professional experts that are having proper skills and knowledge of product development.
No doubt the use of fresh technology and modern tools has helped us in making the superior quality of SS tubes. The tubes are regularly checked by the quality controller team that is checking it intelligently so that no poor quality of tubes is created. We consider national and international product quality standards for the development of the product.
Few good qualities of the tubes-
• Dimensional accuracy
• Smoothness in surface finishes
• Holds high pressure and high temperature
• Pitting, oxidation, SCC, crevice corrosion resistance
Few important test certifications are provided to the buyers by our industry is like manufacturer test certifications accordance with En 10204/3.1b. Also, we provide test certifications like 100% radiography test report, third-party inspection record report, buyers report, etc.
We are too providing the documentation to the buyers at the time of delivering. These are lot helpful to us in clearing the doubts regarding the product quality and also ensure all buyers that we are fairly dealing. List of few essential documents provided by us-

Prior to the dispatching of the tubes to the buyers we are sending each and every produced piece for the testing. The testing is done by us to make sure that the manufacturing of tubes is done according to the industry setup manufacturing norms and as per national/international product quality standards. The tests done by us is Positive material identification test, hardness test, intergranular corrosion test, pitting resistance test, mechanical test, chemical test, etc.
The packaging of the Stainless Steel N08904 Seamless Tubes is done with lot care so that damage free delivering of the product is done. Thus we conduct packaging in wooden cases, wrapping in polyethylene sheets and in bundles (hexagonal) tightly. This doesn’t allow all our produced ranges of product to get damages when it is delivered to the buyers. Also, we are doing the product packaging as per the clients' demands.
