What is the q345r material specification flame cutting

BBN steel company was founded in 2000, starting the international business in 2010 and successfully being approved and certified by ISO9001:2008. After ten years development, BBN steel has become the large-scale comprehensive enterprise group, combining steel trading, q345r material specification plate processing, and steel distribution, also have large warehouse and processional representatives both inTianJin, Zhengzhou and Beijing city.

Q460 steel plate has very high strength and is widely used in large ships, bridges, power station equipment, medium and high-pressure boilers, high-pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. The price of q345r material specification, Q460 steel plate is related to the specifications. Generally speaking, the thicker the thickness, the higher the price. And q345r material specification, Q460 steel plate price is also related to the market situation. When the market demand is in the peak season, the steel supply exceeds the demand, the price will rise. Otherwise, the price may be lowered. Finally, it is related to the order quantity. The larger the quantity, the more advantageous the price.

35# steel is a high-quality medium carbon carbon structural steel, with good plasticity and appropriate strength, good process performance, and acceptable welding performance. It q345r material specification is often delivered in normalized and tempered state. 35 # steel is widely used in the manufacture of various forged and hot-pressed parts, cold-drawn and q345r material specification upset forged steel, seamless steel tubes, and parts in machinery manufacturing.

Between alloy wear-resistant layer and the substrate of wear-resistant steel is metallurgically bonded. Through special equipment and automatic welding process, high-hardness self-shielding alloy welding wire is uniformly welded on the substrate, and the number of composite layers is one to two or even multiple layers. During the compounding process, due to the different alloy shrinkage ratio, uniform transverse cracks occur. It is a distinctive feature of wear-resistant steel plates, q345r material specification.

q345r material specification, P355GH plate mechanical properties: P355GH steel plate thickness/mm:> 60-100: tensile strength σb / MPa: 490-630; yield strength σx / MPa:> = 315 Impact absorption energy AKv / J:> = 34. Steel plate thickness / mm:> 100-150: tensile strength σb / MPa: 480-630,y ield strength σx / MPa:> = 295 Impact absorption energy AKv / J:> = 34. Chemical composition % (C:0.10-0.22, Si:<=03.60, Mn:1.00-1.70, Nb:<=0.010, Ti:<=0.03 S:<=0.030, P:<=0.025, Cr:<=0.30, Ni:<=0.30, Cu:<=0.30, Mo:<=0.10, V <=0.02)
