Two ingredients are not the same, round (one steel) belonging to the ordinary low-carbon steel, alloy steel, other steel mostly. 3 is not the same intensity, low round strength, high strength steel the other, that is the same size in diameter as compared with other steel bar, round bar can withstand tensile steel than other small, round plastic but stronger than other steel that bar before pulled off a larger deformation, while other steel pulled off before deformation is much smaller. Carbon content of less than 1.35%, with the exception of iron, carbon and limited within the silicon, manganese, phosphorus, sulfur and other impurities, excluding steel other alloying elements. Performance depends on the carbon steel carbon content. Carbon content increases, the strength of steel, the hardness increases, ductility, toughness and weldability decrease. Compared with other types of steel, carbon steel earliest use, low cost, wide performance range, the largest amount. For nominal pressure PN≤32.0MPa, temperature water, steam, air, hydrogen, ammonia, nitrogen, and petroleum products and other media of -30-425 ℃. Common brands are WC1, WCB, ZG25 20,25,30 and high quality steel and low alloy structural steel 16Mn. The formula for the round: Diameter * diameter * 0.00617 = weight per meter 1. Press the chemical composition of carbon steel chemical composition (ie, carbon content) can be divided into low-carbon steel, carbon steel and high carbon steel . (1) low-carbon steel, also known as mild steel, the carbon content from 0.10 to 0.30% of low-carbon steel is easy to accept a variety of processing, such as forging, welding and cutting, commonly used in the manufacturing chain, rivets, bolts, shafts and the like. (2) the amount of carbon in the steel of 0.25% to 0.60% of the carbon steel. Have killed steel, semi-killed steel rimmed steel and other products. In addition to carbon also contain small amounts of manganese (0.70% to 1.20%). According to the quality of products is divided into ordinary carbon steel and high-quality carbon structural steel. Good thermal processing and cutting, welding performance is poor. Strength, hardness higher than mild steel, and the ductility and toughness lower than mild steel. Without heat treatment, the direct use of hot-rolled, cold-drawn materials, may also be used after heat treatment. Quenching and tempering of steel has good mechanical properties. The highest attainable hardness of about HRC55 (HB538), σb is 600 ~ 1100MPa. So at moderate intensity levels for various applications, carbon steel the most widely used, except as a building material, but also used extensively for the manufacture of mechanical parts. (3) high-carbon steel is often called tool steel, carbon content from 0.60 to 1.70%, can be hardened and tempered. Hammers, crowbars and other carbon content of steel by 0.75%; cutting tools such as drills, wire tapping, reamers and other carbon content of steel by 0.90 to 1.00% of.

Press the steel quality classification according to the quality of steel can be divided into ordinary carbon steel and high-quality carbon steel. (1) ordinary carbon steel, also known as ordinary carbon steel, restrictions on carbon content, the performance range as well as phosphorus, sulfur and other elements in the residual wide. In China and some countries are divided into three categories based on the delivery guarantee conditions: Steel Group (A type of steel) is to ensure that the mechanical properties of the steel. B Steel (B class steel) is to ensure that the chemical composition of the steel. Special type of steel (C type steel) is both to ensure the mechanical properties but also to ensure the chemical composition of the steel used in the manufacture of the more important structures. China is currently the largest production and use of carbon content of about 0.20 percent of A3 Steel (Group 3 steel), mainly used in engineering structures. Some carbon structural steel further adding a slight amount of aluminum or niobium (or other carbide-forming element) forming a nitride or carbide particles to limit grain growth, strengthen the steel, save steel. China and some countries in order to meet the special requirements of professional steel, chemical composition and properties of ordinary carbon steel to be adjusted in order to develop a series of ordinary carbon steel specialty steel (such as bridges, buildings, steel, pressure vessel steel, etc.). (2) high-quality carbon structural steel and ordinary carbon steel compared to sulfur, phosphorus and other lower levels of non-metallic inclusions. Depending on the carbon content and applications, such steel roughly divided into three categories: ① less than 0.25% C steel is low, especially in the carbon content of less than 0.10% of the 08F, 08Al, etc., because with good depth Chong and weldability and is widely used as a deep-drawn parts such as automotive, cans, etc ....... 20G is a common boiler manufacturing the main material. In addition, low-carbon steel is also widely used as hardened steel, used in machinery manufacturing. ②0.25 ~ 0.60% C for carbon steel, much used in the quenched state, production machinery parts manufacturing industry. ③ more than 0.6% C for high carbon steel, used for the manufacture springs, gears, rollers, etc. Depending on the amount of manganese, manganese content can be divided into ordinary (0.25 to 0.8%) and high manganese content (0.7 to 1.0% and from 0.9 to 1.2%) two steel groups. Manganese can improve steel hardenability, strengthening ferrite and improve the yield strength of steel, tensile strength and abrasion resistance. Usually after a high grade manganese steel additional markings "Mn", such as 15Mn, 20Mn to distinguish normal manganese content of carbon steel. 3. Use classification by purpose is divided into carbon structural steel, carbon tool steel. Carbon tool steel carbon content of between 0.65 to 1.35%, after heat treatment to obtain high hardness and wear resistance, mainly used in the manufacture of various tools, cutting tools, dies and gauges (see tool steel). Carbon structural steel in accordance with the yield strength of steel is divided into five grades: Q195, Q215, Q235, Q255, Q275 due to the different quality of each grade is divided into A, B, C, D grades, most four, some only a ; Another way to distinguish the steel smelting deoxygenation. Deoxy method Symbol: F-- b-- boiling steel semi-killed steel Z-- killed steel TZ-- killed steel A36 special this time round split plan proposed early in BHP Billiton CEO Andrew Mai Anzhe (AndrewMackenzie) took office Initially, it started brewing. May 2013, Mai Anzhe replace high Reese (MariusKloppers) become global CEO and BHP. Tenet, Mai Anzhe carefully studied the A36 will round portfolio and BHP Billiton, and conscious of commodity supply and demand in the coming years will be more balanced, so prices will likely fall, which means that BHP Billiton needed to better focus on improving production efficiency , increase production and reduce costs. Corresponding to this plan, will be BHP Billiton's portfolio and appeared to be quite complex, Mai Anzhe strategic decision to shrink. A36 round the first half of fiscal year 2015, BHP Billiton earnings growth due to efficiency gains brought beyond expectations, reaching $ 2.4 billion. According 麦安哲 plan for fiscal year 2015, BHP Billiton's new investment is only $ 12.6 billion, while in 2016 this figure will be reduced to $ 10.8 billion. For BHP Billiton tend to continue to develop the project, whose goal is to yield more than 20%. A36 round Currently, BHP Billiton 13 countries on six continents, there are 41 assets. Core assets which have 19, located in eight countries on three continents. These core assets, including oil, copper, iron ore, coal and potash, constitute the 2014 fiscal year, BHP Billiton 96% of the source of profits. The first step A36 round strategic contraction, is to divest non-core assets. The main asset of this split involved, mostly from 2001 BHP Billiton acquired the British (Billiton) the company's business. A36 round if they can be approved in the shareholders' meeting on May 6 in Perth, Australia and London on, then, BHP Billiton shareholders may obtain the same number of shares in accordance with its stake South32. South32 stocks were expected to be May 18 in Johannesburg Stock Exchange (JSE), 5 月 A36 round at the London Stock Exchange (LSE), 6 月 2 日 stock exchange in Australia on the 26th (ASX) traded, the new company plans starting from December 31 this year will be a minimum of 40% per annum of the main profit as dividends distributed to shareholders. A36 round at BHP Billiton's management appears that this split plan to BHP Billiton and South32 will bring in revenue. A36 round of BHP Billiton, the sale of mining assets in the current environment is very difficult. If you want to sell some assets, may require 5-7 years. And now, just a transaction, you can put BHP split into two companies.
