Technical data of the original chemical composition (%)
- Q:Excuse me, Shagang steel steel, what is the sign of
- The two is the performance of classification (class), for example, China's current implementation of standards, (G B1499.2-2007) for steel wire for 1499.1-2008), according to the strength (tensile strength yield point / steel) will be divided into 3 levels; the Japanese industrial standard (JI SG3112), according to the comprehensive performance of the steel branch for the 5 species; the British Standard (BS4461), also provides some level of performance test of thread steel. In addition, the thread steel can be classified according to the use, such as reinforced concrete, ordinary steel bars and reinforced concrete bars for heat treatment.
- Q:What does "4esg25" mean on thread steel?
- The letters on the reinforcement are registered plant names or trademarks. The top figures on the bar represent the grade of the reinforcement, such as 3 for grade 2 steel, 4 for grade 3 steel, and 5 for grade 4 steel. The numbers in the back represent the specifications of the bars, and the letters between grades and specifications represent the steel manufacturer.
- Q:What are the different uses of wire rod and thread steel?
- The wire is widely used, in addition to the direct reinforcement for building, and also can be processed into various kinds of special wire, such as spring steel wire and wire, galvanized wire, communication wire, steel cord, steel strand, etc.; it can also be processed into other metal products, such as rivets, screws, nails, etc.. According to data statistics, the general national wire output accounted for 5-15% of total steel output. China is now in the period of economic development, and a large number of wire rods are still needed for urban construction and settlement of residents' living conditions. In addition, the domestic demand for metal products increased, and the export volume of international trade continued to expand. China's wire output accounted for about 15% of the total output of steel.
- Q:What is the carbon content of thread steel?
- The carbon content in the threaded steel is best about 1%, so that it can not only ensure the strength and hardness of the thread steel, but also ensure its plasticity and toughness.
- Q:What is the specific concept of thread steel through water and what is the difference?
- Most of the thread steel is subjected to self - tempering after water cooling, and the tempered bainite is obtained. The advantage is that the strength will be better; the disadvantage is that after rolling through water, the surface oxide film of steel is destroyed, rust is sure
- Q:Why is round bar more expensive than thread steel?
- Round steel has a wide range of applications, many brands and different uses. Such as machining, shipbuilding and other user processing requirements are also different. Such as alloy round steel, Q345B, high carbon steel, 45#, 35#, general round Q235B, mainly material, ingredients, etc..
- Q:How to recognize high quality thread steel
- When we buy rebar, we should not only look at the size of the thread steel, but also use the vernier caliper to measure whether the size meets the requirements. A lot of times, inferior thread steel through the flat flat way to deceive the buyer's vision, so from the steel reinforcement to observe the end of the steel is flat oval, meet the requirements of the thread steel is basically round.
- Q:25 screw steel, how many meters per meter?
- 25 thread steel one meter 3.86kg.Method of calculation: 0.00617 times the square of the diameter of the steel bar. The weight of each diameter of the steel bar (kg) can be calculated.Steel is known as hot rolled ribbed bar.
- Q:What does "4EDT6" mean on thread steel?
- Steel wire is another cold processing product of wire rod. According to the different shape of round steel wire, flat wire and triangle wire etc.. In addition to direct use, steel wire is also used for the production of steel wire ropes, steel ridges and other products.
- Q:Thread steel generally used for more?
- Bars of 6.59 mm in diameter, most of which are rolled into strips; 1040 mm in diameter, usually
