  • IntroductionStainless steels are selected for applications where their inherent corrosion resistance, strength and aesthetic appeal are required. However, dependent on the service conditions, stainless steels will stain and discolour due to surface deposits and so cannot be assumed to be completely...

  • Salt spray testing is an accepted method for assessing the suitability of stainless steel parts and fabrications that are likely to encounter chloride environments in service.For any particular part,...

  • The most common types of corrosion in stainless steel are:Pitting corrosion - The passive layer on stainless steel can be attacked by certain chemical species. The chloride ion Cl- is the most common of these and is found in everyday materials such as salt and bleach. Pitting corrosion is avoided b...

  • IntroductionMost stainless steel types and forms, ie wrought or cast, can be successfully electropolished. Electropolishing of sulphurised free-machining grades, however, does not give a high standard of surface finish.The anodic dissolution of a thin layer of the surface is similar in principal to...

  • Stainless steel is theoretically 100% recyclability and its long term life makes it an ideal environmental performer much better than many other materials. Stainless steel products are designed to ha...

  • Corrosion mechanisms in stainless steelIntroductionStainless steels are generally very corrosion resistant and will perform satisfactorily in most environments. The limit of corrosion resistance of a...

  • Yes. Stainless and carbon steels can be welded together. It is important to use a filler metal that is appropriate for the stainless steel. It is important to note that galvanic corrosion may be a pr...

  • Stainless steel products (sheets, plates, bars, wire etc.) are usually supplied in the “annealed” condition. That means that the last operation is to heat the material up a temperature where the r...

  • Austenitic stainless steel grades are the number one choice for materials that can endure corrosive environments. Austenitic stainless steel tube is rich in chromium and nickel, which make it ideal ...

  • The cleaners of stainless steel can be kept while in storage being processed or during use, the greater the assurance of optimum corroison resistance. Some tips on the care of stainless steel are listed below:1.Use paper or other, protective wrapping on the surface of the stainless steel until pro...

  • Our tubes can get fully welding and smooth inner welding, without blister, leak welding or back line through the good control of welding and grinding technology of welding current and speed proportion. And we never put the welding line on the corner of the square and rectangular tubes. ...

  • Comparision of the suface of ornamental stainless steel tube The surface of our tubes are with high quality which without scratching, pittings, sand holes. And ...

  • Introduction of the advantages of our raw material Our tubes are made from first class material which produce by famous suppliers , such as BAOSTEEL, TISO, TSINGSHAN, etc., which can make sure the high stability and corrosion resistance. And the surface of the t...

  • What is a Standard Finish?“Standard” finishes are produced on an on-going basis. They are generally available off the shelf or can be obtained with a short lead-time. They are the finishes that are used for most stainless steel applications. Standard finishes are categorized as either “Mill” or “Polished”.“Mill” finishes are the least expensive finish option. There are both hot- and cold-rolled mi...

We ca...

  • Importance of surface finish in determining corrosion resistance Lack of knowledge in this area is a major cause of problems. Most specifiers and designers understand the importance of selecting a grade of stainless steel, for example 1.4301 (304) or 1.4401 (316). But s...

  • Vinmay established a strict quality inspection system and scientific examination standards. All of our tubes are produce strictly according ASTM A554 / EN10296-2 Standard.Before the production, we will have the checked the quality of the raw material. The chemical component of the raw material will be inspected by the professional assay offices. And the thickness and surface of the raw material wi...

  • Steel crate package, which suit to the tubes need to be protected well.

  • The Quality inspectors inspect the tubes during each production processes from raw material,tube welding,polishing,packaging.1,Before the production of each machine, we will have the first checked and record the data.2, During the production, our inspector and engineer have been carefully moniting and we record the data every two hours.

  • After high standard requirements on polishing process,we can meet the requirements of electroplating,fine polishing and other application as the result of good smoothness and brightness of our tubes without any pitting,sand hole.1)As for the mirror polish square/rectangular tube , we will polish it as least four times)2)During the polishing processing, we set a special sanding wheel to polish the ...
