What makes something steel stainless steel
What is stainless steel?
Stainless steel is a alloyed or unalloyed steel, a metallic material that is characterized by its special degree of purity. Stainless steel can be made of iron, chromium, nickel, molybdenum or manganese. Very common are steels that rust free are called stainless steel.
The whole thing is divided into different steel groups, stainless steel being one of the high-purity steels. Stainless steel can be alloyed as well as unalloyed. Unalloyed stainless steel means that, from a chemical point of view, the stainless steel consists only of iron and a small part of carbon. In the case of an alloyed stainless steel, further alloy elements can be present.
Appearance and properties of stainless steel
Has stainless steel many different properties. It is corrosion-resistant, temperature-resistant, durable, hygienic and conductive. The stainless steel also has a very thin passive layer on the surface. This can be renewed with the help of oxygen, the relative humidity and a certain chromium content, if it is slightly damaged. Stainless steel does not need any surface protection coatings. Stainless steel is whitish-silver and often has a glossy surface, although this can also be matt-glossy due to different surface treatments.
Processing methods of stainless steel
There are different types of surface treatment for stainless steel:
- Grinding and polishing
- to brush
Will be stainless steel sanded and polishedso this is a mechanical form of machining. During this process, material is removed. Carrier materials with hard abrasive particles are used for this. The whole thing can be used for different machines, such as finger grinders, belt grinders or angle grinders. Stainless steel is grinded to make surface layers like Remove tarnish or weld beads. For decorative reasons, the whole thing is then polished with a polishing agent for stainless steel.
The so-called Wobble, becomes the surface shinier and smoother. Not much is removed from the surface. Pastes, polishing agents and various liquids are used. The stainless steel with its shiny and smooth surface is often used in the pharmaceutical industry.
Another way to treat stainless steel is that to brush. Here, too, something is removed from the surface. The aim is to give the surface of the stainless steel a special structure To provide. Hand pads, straps or disks are used for this.
Use of stainless steel
Stainless steel is used in a number of areas, here are a few examples:
- Furniture industry
- Food industry
- Pharmaceutical industry
- vehicle construction
- mechanical engineering
Stainless steel is used, among other things, in the pharmaceutical industry, the food industry or in architecture due to its corrosion resistance and acid resistance. Stainless steel is often used in the furniture industry because it is corrosion-resistant, hygienic and durable. On the other hand, because it looks particularly elegant when it is decorative, for example on beds. We also offer great furniture made of or with stainless steel in the Wohnen.de shop.
