Understanding Stainless Steel Corrosion and How to Prevent It Stainless steel is known for its excellent corrosion resistance, but it is not completely immune to corrosion. Corrosion of stainless steel occurs when it is exposed to certain environm...

Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by making it easier for more iron oxide to form. Since iron oxide has lower density than steel, the film expands and ten...

𝐖𝐡𝐚𝐭 𝐌𝐚𝐤𝐞𝐬 𝐒𝐭𝐚𝐢𝐧𝐥𝐞𝐬𝐬 𝐒𝐭𝐞𝐞𝐥 𝐌𝐚𝐠𝐧𝐞𝐭𝐢𝐜? For stainless steel to be magnetic, it must contain iron in its chemical composition. That takes care of the first requirement.The second requirement is that the stainless steel must have its crystal structure be arranged in a ferrite or ...

What's the application of nickel? Nickel is primarily sold for first use as refined metal (cathode, powder, briquet, etc.) or ferronickel. About 65% of the nickel consumed in the Western World is used to make austenitic stainless steel. Another 12% goes into superalloys (e.g., Inconel 600) or nonferro...

how does stainless steel improve modern day life?Stainless steel has many environmental and social benefits. Stainless steel products enable us to lead a healthier life and are cleaner for the environment as well. Even though it is impossible to demonstrate all areas where it is beneficial, below are some of the main examples where stai...

Hot rolling is above the recrystallization temperature of rolling; Cold rolling is below the recrystallization temperature of rolling, both are based on the hot strip rolling. And then recover its mechanical properties by annealing . It generally under process such as hot rolling,acid pickling, col...

Stainless steel 304# and 316# are the most popular types of stainless for railing systems. Railing systems made from each of these two types offer different strengths and weaknesses. Understanding yo...

Stainless steel is 100% recyclable. An average stainless steel object is composed of about 60% recycled material of which approximately 40% originates from end-of-life products and about 60% comes from manufacturing processes. According to the International Resource Panel's Metal Stocks in Society ...

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...

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...

It is so important that water is kept clean, not just for our health but for the environment as well. Stainless steel can be used to improve the cleanliness of water. The list below shows how stainless steel can help keep water cleaner:Stainless steel pipes for drinking systems help to keep water c...

We use crane to take the tubes up . It's the safety and efficiency way to transport the bundles in our factory. ...

As you may know, many of our tubes are export to Europe countries. And most of our clients in Europe require to pack the tubes in hollow plate. Normally , the total weight for a bundle of tubes packed by hollow plate is 500kg which is very hard for manual loading. Therefore our company use a sp...

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...

Most decisions about which steel to use are based on a combination of the following factors:What is the corrosive environment? – Atmospheric, water, concentration of particular chemicals, chloride co...

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...

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...
