Crane Manufacturers And Services- SGF Fab Industries

1. Crash Course on Steel and its Properties In a series of two blogs titled "Know Your Iron'', readers were made cognizant of Fe's chemical as well as physical properties. (Read the blog - https://sgffab.blogspot.com/2018/10/everything-to-know-about-iron-from-sgf.html) In this article, chapter and verse on steel and stainless steel would be given. Metals like iron, aluminum, copper, et al are extensively used in the construction industry. Their importance is manifold as they provide a scaffolding that stands the test of time. These metals, dovetailed with know- how and innovation, have produced a plethora of mesmerizing marvels in the world. These metals bear the weight of globalization, industrialization, and innovation. Companies and industries are constantly putting together these strong, robust metals and their resilient alloys to develop novel and sturdy machines and implements. Source - indiasteel.in One such giant is single girder crane manufacturers SGF Fab. These log handling crane manufacturers have established an irreproachable name for themselves in the construction equipage industry. SGF Fab provide infallible cranes, material handling equipment, and industrial fabrications that escalate a gamut of activities. What distinguishes these grab manufacturers in India is their service of

Steel, like some vital alloys, is ineluctable. Let's have a gander at steel and its properties. History Commercial steel production in the late 19th century was a result of Sir Henry Bessemer's creation of an efficient way to lower the carbon content in cast iron. By lowering C's amount in iron to about 2 percent, the much harder and more malleable metal product of steel is produced. However, for a 360 view of the history of steel, you'll have to go back 4,000 years to the beginning of the Iron Age. Steel has been with us for a very long time. Production Today, most steel is produced by basic oxygen methods (also known as basic oxygen steelmaking or BOS). BOS derives its name from the process that requires oxygen to be blown into large vessels containing molten iron and scrap steel. Although BOS accounts for the largest share of global steel production, the use of electric arc furnaces (EAF) now accounts for about one-third of all steel production. Grades According to the World Steel Association, there are over 3,500 different grades of steel, encompassing environmental properties. You might be wondering how there can be so many different grades of steel when steel is only composed of iron and carbon. That's because the amount of carbon as well as the level of impurities and additional alloying elements determine the properties of each steel grade, and those combinations reach very high numbers. Commercial steel is generally classified into four groups depending on their metal alloy content - unique physical, chemical, and 1.Carbon Steels (which include low carbon, medium carbon, and high carbon steels)

3. 2.Alloy as manganese, silicon, nickel, and chromium) 3.Stainless Steels (which contain about 10 percent chromium and are classified as austenitic, ferritic, and martensitic) 4.Tool Steels (which are steels that are alloyed with high temperature and hard metals, such as molybdenum and tungsten) Steels (which include such common alloy metals A wide range of alloy compositions allow steel to have diverse mechanical properties. Properties Different types of steel are produced according to the properties required for their application, and various grading systems are used to distinguish steels based on these properties, which include density, elasticity, melting point, thermal conductivity, strength, and hardness (among others). According to the American Iron and Steel Institute (AISI), steels can be broadly categorized into four groups based on their chemical compositions: 1.Carbon Steels 2.Alloy Steels 3.Stainless Steels 4.Tool Steels Applications It is steel's properties that have made it the most widely used and most recycled metal material on earth. From stainless and high-temperature steels to flat carbon products, steel's various forms and alloys offer different properties to meet a wide range of applications. For these reasons, as well as the metal's combination of high strength and a relatively low production cost, Steel applications make steel a durable and aesthetic metal used today in countless products. This information on steel is just a drop in the ocean. However, the above paragraphs cover a substantial amount of information on this magical, humble alloy. Types of Stainless Steel

4. There are five major types of stainless steel. They are - Austenitic stainless steels are 200 series or 300 series. They are non magnetic and have high corrosion resistance. They can be hardened only by cold working – not by heat treatment. They are highly formable. But, they are prone to stress corrosion cracking. There are three subtypes: straight, L and H. L types have higher corrosion resistance than the straight types. Austenitic stainless steels are used in shafts, valves, bolts, bushings, nuts, aircraft fittings, chemical equipment, food processing equipment, brewing equipment, cryogenic vessels, etc. Ferritic stainless steels are 400 series. They are magnetic. They have lower ductility and lower corrosion resistance than the austenitic grades. But, they offer high resistance to stress corrosion cracking. They are hardened by cold working and are not heat treatable. Typical applications are heat exchangers, automotive fasteners, furnace parts, and heater parts. Martensitic stainless steels are 400 series and 500 series. They are magnetic. They have higher strength, higher wear resistance and higher fatigue resistance than the austenitic and ferritic grades. They can also be heat treated. But, corrosion resistance is moderate and lower than the austenitic and ferritic grades. Major applications are machine parts, pump shafts, bolts, bushings, coal chutes, cutlery, hardware, jet engine parts, mining machinery, rifle barrels, screws, valves, aircraft fittings, fire extinguisher inserts, and rivets. Precipitation Hardening Grade Stainless Steels are also called PH types. Their corrosion resistance is equivalent to that of austenitic grades and strength is generally higher than that of martensitic grades. They also retain high strength at elevated temperatures. They are heat treatable, and are mainly used in aerospace industry for aerospace structural components.

5. Duplex stainless steels are mixture of austenitic and ferritic. They provide higher corrosion resistance than the austenitic stainless steels. They are also more resistant to stress corrosion cracking than the austenitic stainless steels. Duplex have higher strength than the austenitic grades. Typical applications are water treatment plants and heat exchanger components. (Inputs from the balance) ___________________________________________________
