Introduction - Stainless Steel

Stainless Steel was introduced to the world in August 1912 when Harry Brearely of U.K . recorded an analysis of a cast made during a visit to Royal Small Arms Factory in Enfield, which showed a carbon content of 0.24% with silicon 0.20% Manganese 0.44% and Chromium 12.86%.

On conducting various tests, he found that the cast was resistant to corrosion and did not rust. Simultaneously two patent applications dealing with austenitic chrome nickel steel were filed by scientists of the German Steel Company "Freid Krupp Gubstahlfabrik, Essen". As of today Stainless Steel is 90 year old.

It is the presence of Chromium (Cr) which renders Steels Stainless and not Nickel as is widely believed. Due to the desired level of Cr, a continuous stable and inert (passive) chromium oxide film forms on the surface, which is its natural built-in resistant to corrosion, both wet and dry. Nickel contributes in reinforcing the corrosion resistant and making it an engineering material. There are five basic categories of Stainless Steel-Austenitic, Ferritic, Duplex, Martensitic & Precipitation Hardening, and the first two account for approximately 95% of Stainless Steel applications.

The Chrysler tower in New York completed in 1929, was crowned with an Art Deco Cap of Stainless Steel. Extra sheets of stainless steel then brought for future maintenance needs, are still kept in storage, having never been required since then, thus bearing permanent testimony to the lasting quality of Stainless Steels.

Tubes and pipes seamless, welded made from Stainless Steel grades are intended for applications requiring resistance to atmospheric attack and to action of inorganic and organic acids, and other solutions. These properties are mainly due to the action of the alloying element chromium that causes passivation of the steel surface in oxidizing environments. According to scale. Chromium content must be at least 12%. Molybdenum and nickel further increase the resistance to corrosion. Other alloying elements, such as Cobalt, Niobium-Tantalum, Titanium, Nitrogen, enable a wide range of stainless grades to be produced with varying chemical, mechanical and physical properties to suit the particular requirements of steel users.

Our company can call upon the production of stainless steel, and our experts are at your entire disposal for any advice or assistance you may require in choosing the material that would best suit your purpose. All you need to do is to state your requirements in detail, describing operating conditions for the intended application.

Normally Pipes and Tubes are manufactured as per ASTM, JIS, DIN, ISI, BS, and GOST etc. and at request of buyer we manufacture and supply the pipes as per agreed specifications.
