Different Grades of Stainless Steel

October 15, 2016 | Author: | Posted in Industrial Mechanical

Stainless steel metal is one of the best commonly used metals in the world. It is prevalently known for its stainless and anti-corrosion assets. It contains chromium and low carbon steel. The chromium pleased offers the anti-corrosion property to the metal. It is presented in different grades and alloys which can be used for different purposes.


Stainless steel


Stainless steel sheets is graded according to its chemical structure, and consequently its differing properties. It is important to become aware with the main types of, as one steel is expected to be more appropriate than another for a specific purpose. In overall, while stainless steel can fight many types of corrosion, all grades are probable to be corroded by chlorides, with those grades which are high in chromium, molybdenum and nickel showing the most resistance. Similarly, while some steel is completely non-magnetic, other types hold their magnetic attraction.


Properties of 200 series:


200 series stainless steel is nonmagnetic, and made up of around 17% chromium, 4% nickel and 7% manganese. Less mutual than the 300 series grade, to which it is most common, it is most regularly used for knives and cooking utensils. It holds strength at high temperatures, and is less disposed to attack from corrosion than the 300 series. Once corrosion has activated, however, it regularly breaks down rapidly. While it can withstand soaking in environments such as seawater, it cannot do so indeterminately, with some corrosion beginning within months.


Properties of 300 series:
300 series stainless steel is also nonmagnetic, and varieties up over 70% of total stainless steel production. As such it can be create in use across a range of applications, comprising domestic architecture and building of planes, trains and automobiles. Containing of approximately 18% chromium and 8% nickel, it is also often used in kitchen utensils and cookery equipment, and is common in its corrosion resisting properties to the 200 series. If used in surroundings without high chloride content, it is tremendously skillful at resisting corrosion, but where chloride levels are high, performance will rapidly decline.


Properties and uses of 400 series:
Different than 200 and 300 series, 400 series stainless steel is magnetic. Comprising approximately 11% chromium and 1% manganese, this series replies well to strengthening through heat, but has poor resistance to corrosion. Without protected, 400 series is not applied for any kind of seawater application. It is most commonly used in applications which needs heat resistance, such as drain pipes, heat exchangers, combustion burners and so on. It should not be used in low temperature environments, as its strength drops rapidly in this condition.


Properties and uses of 600 series:
In a alike method to the 400 series, 600 series stainless steel can be heat treated to tremendously high strength levels (important to the common situation to this series as ‘precipitation hardening’ ), showing tensile strength of up to double the 300 series. It also recollects its magnetism. Defenseless to chloride environments, 600 series is also vulnerable to stress extremely when corroded. Most 600 series can only continue in seawater without corrosion for a few days. Similarly to the 400 series, this type should not be used in low temperatures.
