These qualities make stainless steel ideally suited to building applications exposed to adverse weather, such as roofs, facades, rainwater recovery systems and domestic water pipes. With five categories of stainless steels available — each differentiated by the alloying elements added to iron, carbon and chromium — w e offer a complete range of solutions. Skip to content What is Stainless Steel? Stainless steel is a corrosion-resistant alloy of iron, chromium and, in some cases, nickel and other metals.
Composition of Stainless Steel. Reaction to Contact with Air, Humidity or Water. General Properties of Stainless Steel. Aesthetics Stainless steel has a great variety of surface finishes, from matt to bright and including brushed and engraved.
Mechanical Properties Compared to other materials, stainless steel has strong mechanical properties at ambient temperatures — it is steel after all!
Corrosion Resistance With a minimum chromium content of Cleanability Stainless steel items are easy to clean, usual cleaning products detergents, soap powders are sufficient and do not damage the surface. Stainless Steel Families With five categories of stainless steels available — each differentiated by the alloying elements added to iron, carbon and chromium — w e offer a complete range of solutions. Austenitics or series 0.
The presence of nickel improves corrosion resistance in certain media and makes stainless steel more ductile. Written by G. What Are Alloys? It contains a maximum of 0. It offers an excellent compromise between strength, ductility, and machinability and is widely used in many applications. Monel is a nickel alloy. It is predominantly composed of nickel with copper and smaller amounts of iron and manganese. Monel is more expensive than steel, but it is highly resistant to corrosion and high temperatures.
It is often used in applications in which components will frequently be in contact with corrosive materials or exposed to very high temperatures. Brass is an alloy of copper and zinc. It is softer and more ductile than steel while being resistant to corrosion, properties that make it desirable in some applications.
This, combined with being resistant to wear and deformation, makes tool steel perfectly suited for use in machining and tool making. These alloying elements can include manganese, chromium, vanadium, nickel, and tungsten. The addition of alloying elements increases overall machinability and corrosion resistance. Alloy steel is most commonly used to manufacture pipes , especially pipes for energy-related applications. I hope you have a better understanding of steel in general and the four groups steel is often broken into: stainless steel, carbon steel, tool steel, and alloy steel.
Posted by: Dani Weinhandl on March 25, Stainless Steel Stainless steel is known for being the most corrosion resistant of the four groups. Carbon Steel Carbon steel and stainless steel have the same basic ingredients of iron and carbon , but where their composition differs is in alloy content.
Common Steel Alloying Elements When it comes to steel, there are many different elements that can be added to the base material, allowing the purchaser to tweak variances until the right alloy is found.
Common alloying elements include the following: Manganese : Used in tandem with small amounts of sulfur and phosphorus, the steel alloy becomes less brittle and easier to hammer. Chromium : A small percentage 0. Vanadium : With only. Mixed together with chromium, the steel alloy becomes much harder, but still retains its formability. Tungsten : Boosts heat resistance, so the melting point is higher.
Also improves the structural makeup of the steel.
