In today's SA573 Grade 65 carbon structural steel shape angle bar steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of SA573 Grade 65 carbon structural steel shape angle bar market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

Thin SA573 Grade 65 carbon structural steel shape angle bar, steel plate is mainly used in automobile industry, aviation industry, enamel industry, electrical industry, machinery industry and other departments. The main requirement of thin steel plate is to facilitate bending and forming. The thinner the steel plate is, the easier it is to bend. The common specifications of thin steel plate include thickness less than 4mm, width about 500-1500mm and length about 1.5-4m.

Pickled steel coils are processed by pickling machines to remove the oxide layer. Because of the deoxidation treatment, certain characteristics of the pickled steel coils are more prominent. First, the surface is smoother and exquisite. For products that require the appearance of the steel plates, pickling steel coil is a good choice. Second, the surface of the pickled steel coil is smooth and not easy to oxidize, and it is convenient and quick to paint. Third, SA573 Grade 65 carbon structural steel shape angle bar, pickled steel coils have high precision.

SA573 Grade 65 carbon structural steel shape angle bar, The wear-resistant composite plate is quenched once and tempered at low temperature. The quenching temperature is 820-850℃ or 780-810℃. If the strength of the core is required to be higher, it should be quenched at 820-850℃ with low carbon M at the core. If the surface hardness is required to be high, the grain size can be refined by quenching at 780-810℃. It is suitable for solid carburized carbon steel and low alloy hardfacing wear-resistant composite plate workpieces, and coarse grain steel carburized by gas and liquid.

S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. SA573 Grade 65 carbon structural steel shape angle bar, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
