Stainless steel is a nickel-chromium alloy and contains 10.5% chromium. The springs made up of stainless steel are resistant to corrosion and hence do not lose their shine in toughest conditions. Due to the resistivity against corrosion, steel is used to make a variety of household, commercial and industrial products.
Steel is basically iron with some traces of carbon. The amount of carbon is based upon the grade of steel being used, for example, it can vary between 0.2-2.1 percent by weight. Several metals are used in the formation of Stainless Steel Spring such as tungsten, vanadium, manganese, 12% chromium and 8% nickel. There is an advantage of using Stainless Steel Springs over Carbon Steel Springs. Many food processing companies and medical industry are resorting to Stainless Steel Spring because of its resistance to rust and damaging effects of chemicals.
Stainless Steel Springs: Types As Per Material
Springs made of Austenitic Stainless steel (with 18% chromium and 8% nickel) are efficient in working at high temperatures, usually up to 344 degree Celsius and they do not get hardened by the impacts of high temperature but by cold-working. These types of Steel Springs are used in making home appliances and food processing machines.
Another type of Stainless Steel Spring is made of ferritic steel (with titanium, niobium, 10-20% chromium, which ensures that it does not get hardened by high temperatures and is highly ductile with great strength) that has some magnetic properties.
Martensitic Steel Springs contain 11-18% chromium and highest amount of carbon than other type of springs. They have some magnetic characteristics and get fractured at low temperatures. But these are not excellent fighter against corrosion.
Precipitation hardening-type Stainless Steel Springs have the integration of martensitic and austenitic type of steel. They show high strength when exposed to high temperatures such as 500-800 degree Celsius. They are highly used in aerospace industry.
So, it can be seen that Stainless Steel Springs exhibit a large variety of hardness and strength and are applicable for different purposes.
Depending on the application, buyers can contact Stainless Steel Springs Manufacturers & Suppliers who can suggest the best material and design to fulfill the purpose.
