Stainless steel

In comparison with aluminium, stainless steel is approximately 3 times heavier. Stainless steel, like steel itself, is an alloy. An alloy always consists of different materials. Among the most frequent alloying elements in non-corrosive stainless steel is chrome, where nickel, molybdenum and further elements are used for special requirements. The magnetisability, as well as the corrosion resistance, are two of these requirements which are controlled by the different alloys.

What is Stainless Steel?

Mazinanian, G. Herting, I. Odnevall Wallinder, Y. For all grades, metals were released at levels close to the detection limits when exposed to artificial tap water, and higher release levels were observed when exposed to citric acid. Increased surface passivation, which resulted in reduced metal release rates with time, took place in citric acid for all grades and test conditions e. There was no active corrosion in citric acid at pH 2. Fe in citric acid and Mn in all solutions, but mostly tap water were preferentially released, as compared to their bulk alloy content, from all stainless steel grades.


As an integrated stainless steel producer, JFE produces stainless steel from steel making stage, to Steel grade. Elongation Functional products provide the corrosion resistance and mechanical properties of stainless steel with lower cost​.


Stainless Steel Grades

Stainless steel types 1. Type is the most versatile and widely used stainless steel. The higher the number the betterthe resistance.

Stainless steel is a material with tons to offer. Its popularity also means there are seemingly a million different types of stainless steel grades. Actually, there are a few hundred. As a general rule, stainless deserves consideration if your engineering project requires at least one of these three qualities:.

Home Stainless What is Stainless Steel? Stainless steel is also environmentally neutral and inert, and its longevity ensures it meets the needs of sustainable construction.

Stainless Steel Characteristics

Stainless steel is not a single material but the name for a family of corrosion resistant steels. Like many scientific discoveries the origins of stainless steel lies in a serendipitous accident. In Sheffield, England, Harry Brearley was investigating the development of new steel alloys for use in gun barrels. The first application of these steels was in cutlery for which Sheffield subsequently became world famous. Simultaneous work in France led to the development of the first austenitic stainless steels. Annual consumption is now well over 20 million tonnes and is rising in areas such as the construction industry and household appliances. New uses are being continuously found for the attractive appearance, corrosion resistance, low maintenance and strength of stainless steel.

ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them. The steels can be of the carbon, structural, stainless, ferritic, austenitic, and alloy types. These steel standards are helpful in guiding metallurgical laboratories and refineries, product manufacturers, and other end-users of steel and its variants in their proper processing and application procedures to ensure quality towards safe use. Additive Manufacturing Standards. Cement Standards and Concrete Standards. Fire Standards and Flammability Standards. Geotechnical Engineering Standards.


Grade SS is the most well-known and commonly used austenitic stainless steel. Austenitic stainless steels contain 15%% chromium and 2%% nickel for better surface quality, corrosion and wear resistance, and workability. “L” denotes low carbon content, which equals increased corrosion resistance.

Why use stainless steel? Corrosion decreases steel mechanical properties and gives it unacceptable aspect for many applications. Steel corrosion is an important.

Stainless steel's resistance to rusting results from the presence of chromium in the alloy, which forms a passive film that protects the underlying material from corrosion attack, and can self-heal in the presence of oxygen.
