  • 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...

  • 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...

  • Stainless steel is usually divided into 5 types:Ferritic – These steels are based on Chromium with small amounts of Carbon usually less than 0.10%. These steels have a similar microstructure to carbo...

  • 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 easy to clean. Washing with soap or mild detergent and warm water followed by a clear water rinse is usually quite adequate for domestic and architectural equipment. Where stainless steel has become extremely dirty with signs of surface discolouration (perhaps following periods o...

  • Stainless steel is divided into five major categories such as namely Austenitic, Ferritic, Martensitic, Duplex and Precipitation hardening stainless steel grades. Nature depends on types of atomic bo...

  • It is often thought that a magnet is used to test the quality of stainless steel. If the stailes steel is nonmagnetic, the product is genuine. If it is magnetic, the product is fake. In fact, this ...

  • 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...

  • Stainless steel surface corrosion can occur. The reasons for this can vary and include inappropriate stainless steel selection for the service environment, surface contamination with iron or carbon s...

  • Yes. The 300 series stainless steel can be "hardened" but only by "work hardening." This is done by cold working the material. This can be done by cold rolling to lighter thicknesses, cold "drawing" ...

  • What is a Non-Ferrous Metal? When a metal is defined as non-ferrous it means that it does not have a significant amount of iron in its chemical composition. Note the word “significant”; nearly all m...

  • Yes. Stainless steel has excellent properties at both extermes of the temperature scale.Stainless steel can be used down to liquid nitrogen temperatures and up to about 1800°F ...

  • The use of the letter L after the grade number(i.e 304L,316L) means that the carbon content is resisted to a maximum of 0.03%, in stainless steels that are not low carbon, maximum levels may be set a...

  • Are all stainless steels non-magnetic?No. The austentic or 300 series stainless steels are generally non-magnetic but high levels of cold work make them somewhat magnetic. Castings made out of these ...

  • Scratches are difficult to remove. Most kitchen appliances , sinks, and counters have a No. 4 polished finish with short directional polishing lines. Restoring this finish to its orginal apperance re...

  • 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 term"duplex"describes the microstructure that is characteristic of this family of stainless steels which is typically equal parts austenite and ferrite. Duplex stainless steels characterized by high strength levels and provide a range of corrosion resistance levels. They are used in application...

  • The first number is the amount of chromium that is contained in the stainless, so 18 is 18% chromium. The second number is the amount of nickel. so 8 stands for 8% nickel. So 18/8 means that this stainless steel contains 18% choromium and 8% nickel. 18/10 is 18% chromium and 10% nickel. Both 18/8 a...
