Stainless steel is an alloy containing iron with a minimum 10.5% of Chromium. Chromium forms a thin layer of oxide (Cr2O3) on the steel surface, known as the ‘passive layer.’ This passive layer prevents the steel from corrosion. The more the Chromium content in steel, the higher it’s resistant to corrosion.
Stainless steel is called stainless because it does not get rust or discolor compared to regular steel. This is because of the chromium content in the alloy.
Stainless steel works differently from plain steel; how?
Stainless steel contains chromium whereas plain steel contains carbon as alloy. The changes carried out by chromium in the steel’s internal structure in the properties that gives stainless steel its name: very high corrosion resistance and a surface that does not stain or tarnish.
Higher Corrosion resistance
Higher Tensile strength
The Chromium present in stainless steel offers a self-healing protective oxide layer that makes it corrosion resistant. The self-healing behavior of the layer means the corrosion resistance remains solid regardless of its fabrication methods.
The corrosion-resistant property of stainless steel will differ with various atmospheres and environments for its different grades. Grades having high chromium content, molybdenum and nickel being the most corrosion resistant of stainless steels.
Tensile strength is the ability of a material to hold or withstand heavy stress or pressure without failure. Tensile strength is studied or measured by the maximum stress that a material can develop while being pulled or stretched before breaking.
Duplex stainless steels have higher tensile strengths than austenitic steels. The highest tensile strengths are seen in the martensitic (431) and precipitation hardening grades (17-4 PH).
Stainless steels have very good strength and good resistance to corrosion and oxidation at very high temperatures. Stainless steels are used at temperatures up to 1700° F for 304 and 316 and up to 2000 F for the high temperature stainless grade 309 and up to 2100° F for 310.
Why Use stainless steel for your custom wire forms?
Stainless steel wire forming is widely chosen when any structure or component will be used in a very harsh environment and at elevated temperatures, moisture, and chemicals. It is used in various industries, including medical equipment, food processing, agriculture, automotive, aerospace, and lighting, commonly employing stainless steels when durability and long-term functions are very important and crucial.
The important role of material handling is to select the appropriate material handling equipment that is safe and can fulfill the need at very minimal possible overall cost. That is easy to hold and use smoothly.
This process uses cavitation bubbles which are produced by high-frequency pressure (sound) waves to agitate a liquid. This agitation produces high forces on contaminants adhering to materials like metals, plastics, glass, rubber, and ceramics. This action also penetrates blind holes, cracks, and recesses. Ultrasonic cleaning is done in aqueous solution. Ultrasonic solution has pH range of 10 or more.
Medical or food equipment sterilization
Stainless steel is also widely used in medical or food equipment sterilization processes and part finishing processes because it does not react further and does not produce a stain.
