These are generally used to manufacture bodies of vehicles, railway coaches, earth moving equipments, material handling equipments, consumer goods like washing machines, bicycles and its parts, office equipments and furniture. Cold-Rolled steels can also be specified as dent resistant or bake hardenable for applications that require dent resistance after forming and painting. Each grade can be processed with several surface finishes depending on customer requirements.
Lubricants can be applied to enhance formability and to avoid at-press lubrication. Hot-rolled steel from which the iron oxides present at the surface has been removed in a pickling process. Pickled Hot Rolled Coil can be found on the market in coil or or in sheets and is further processed into finished products by the manufacturer.
Hot Rolled steel is heated at a very high level over o F and is pressed into shapes. It is generally used in parts where rust proofing is not critical. There are processes that allow hot rolled sheets to prevent rust as well. Hot Rolled sheets have the most flexibility regarding how parts are welded together as well. This is the most basic form of carbon steel. Steel becomes very mouldable when heated at high temperatures, but is extremely strong and almost impossible to mould when at room temperature.
It becomes completely unbendable after cooling. This is why there are many shapes to hot rolled steel products, and relatively few Cold Rolled Steel Shapes. Hot-dip galvanizing is a form of galvanization. It is the process of coating iron or steel with a thin zinc layer, by passing the steel through a molten bath of zinc at a temperature of around o F o C.
When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbon dioxide to form zinc carbonate, a dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements.
Galvanized steel is widely used in applications where rust resistance is needed, and can be identified by the crystallization patterning on the surface often called a "spangle".
Galvanized steel can be used in extreme heat. As a matter of fact, galvanized steel can be exposed to around o F before the Zinc will begin peeling from the steel.
Stainless Steel is a very versatile and useful material used in a wide variety of applications. It is do used in the Architecture, building and construction field. Stainless steel differs from carbon steel by amount of chromium present.
Carbon steel rusts when exposed to air and moisture. This iron oxide film is active and accelerates corrosion by forming more iron oxide. Stainless steels have sufficient amount of chromium present so that a passive film of chromium oxide forms which prevents further surface corrosion and blocks corrosion spreading in the metal's internal structure.
High alloy steel used mainly for its anti-corrosion properties and contain a minimum of Stainless steel is more expensive than carbon and alloy steel and only accounts for a small number of steel used in the global market, but it is nonetheless a very valuable international market.
It is non-magnetic, not heat treatable and has good formability. By adding molybdenum, the corrosion resistance is increased. It is used in a food equipment, chemical equipment and architectural applications.
EG Obtained by electro-plating the finished Cold Rolled Steel with a thin layer of zinc or zinc-nicket to provide corrosion resistance. Electro-galvanized Coil can be found on the market in coil or in sheets and is further processed into finished products by the manufacturer. Electro-galvanized coil features excellent forming properties, paintability, weldability, and is suitable for fabrication by forming, pressing and bending.
Applications include domestic applications; building applications for example, wall elements, roofing applications, automotive applications for example, body in white for vehicles under body auto parts , lightning fixtures, drums and various kinds of sections applications, profiled sheets.
Pure aluminium is soft and ductile and most commercial uses require greater strength than pure aluminium affords. So, strength is achieved by the addition of other elements to produce alloys. Further strengthening is possible by means which classify the alloys into roughly two categories, non-heat-treatable alloyed with manganese, silicon, iron and magnesium and heat-treatable alloyed with copper, magnesium, zinc, and silicon.
Aluminium is available in a wide variety of alloys to meet specific applications. This article focuses on the alloys commonly used by DSM in precision sheet metal. When aluminium is bent around too small of an inside radius, cracking will occur.
Cracking is the most pronounced when the runs parallel to the natural grain of the material formed as the sheet is rolled from the molten ingot. It is generally a good idea to keep the inside radius at least equal to the material thickness. The more the merrier. All Rights Reserved.
