Metals are used in furniture, equipment, machines and tools. However not all of the metals can be used in moist environmentsand surroundings that contain chemicals. This is because metals easily react with oxygen and other elements through oxidation and reduction. This reaction reduces the molecular structures and this directly affects the mechanical and chemical properties of the material. One of the common reactions is rusting which is also generalised as corrosion of metal. To prevent and avoid corrosion certain measures and alloys are formed which provide maximum cover against reactions used under normalatmosphericconditions.
Steel is mostly used in construction and parts development due to its superior qualities such as hardness and toughness. Since these equipment are to be used in reactive conditions galvanisation of carbon steels is required since stainless steel has integral corrosion resistance. Galvanized steel are common because they are cheap in the market and the ease of fabrication is supported by its flexible character as compared to stainless steel.
Galvanisation is one of the many protective coating used to shield the main material from corrosion. Protective coatings use sacrifice protection by selecting certain highly reactive metal which form oxides on the layers of the main material that halts further corrosion. Galvanisation uses zinc metal to coat the outer surfaces of iron or steel. They use common methods like hot-dip galvanisation which involves immersing the fabricated steel products into a bath of molten zinc which is diffuses the metals together.
Galvanisation if mostly done as a finishing processesin any fabrication project. Before galvanisation is done certain treatments must be done like degreasing, pickling, rinsing and fluxing which help in removing impurities such as other metal oxides, dirt, oils and chemicals. This process is done under high temperatures and involves using of certain chemical baths to facilitate such treatments. It is a continuous process taking close to 12 hours to reach the quenching process.
The reason why stainless steel is more expensive is the exemplary properties that t contains. The chromium, carbon and iron alloy forms a highly corrosion resistant metal with a shiny surface texture. The stainless come in different grades such as the Ferritic, Austenitic, Martensitic, Duplex and other modifications made. This metal has resistance to shock or impact, it has high level of corrosion resistance, it requires no finishing process thus have a natural aesthetic appearance, and has a long life cycle; these and other properties has made it favourable in the engineering fabrication , processing and manufacturing industries.
Using both of the materials helps you benefit in cost since the carbon steel is cheap. This also reduces the maintenance cost of the equipment or tools that have been designed by these two materials due to their ability to resist corrosion; this also gives you more usage time under any reactive condition. Both of the materials develop high strength and toughness which makes it reliable in it use. The shinyappearance and colour makes it easy to identify and clean. In case you want steel metal that can survive critical salty condition, stainless is the best. Their durability makes them compatible when considering both as your material selection.
