Q345:it is a kind of manganese steel (16Mn), yielding strength of 345, good welding performance, commonly used in structural parts welding, low carbon steel, can not be used for quenching or quenching and tempering.No. 45 Steel:high quality carbon structural steel, medium carbon steel. Can be used for quenching or tempering. Learn About Quenching & Tempering Clifton SteelSteel is strong to begin with, but sometimes its necessary to make it even stronger. One of the common treatments to achieve this is quenching and tempering. This is a process that strengthens and hardens iron-based alloys by heating, rapidly cooling, and reheating. Modeling and Composition Design of Low-Alloy Steels The quenching sample range is [850, 1100]. In the quenching stage, in order to make the steel fully austenitized, the lowest temperature is selected to be 850 °C. If the quenching temperature is too high, it will cause overburning of the quenched steel, causing the steel to easily crack and brittle.
Description. Seamless carbon steel pipe is the kind of seamless steel pipe which is made from carbon steel billets as the basic material. The carbon seamless steel pipe has no seam or weld-joint around its body by internal seamless welding process. Due to the tough and flexible nature of carbon steel, the carbon steel seamless pipe have excellent finishing, better durability and high strength Steel plate - Sunny SteelQuenching and tempering is a two-step heat treatment process. In the quenching step of this process, steel is heated to a temperature between 1,500-and 1,650-degrees Fahrenheit, then rapidly cooled with water. In the tempering step, the steel is then re-heated to a below-critical temperature between 300 and 700 degrees and air-cooled. The Market Demand of Alloy Steel Pipe_DatangAlloy steel pipe is suitable for power plant, boiler plant, chemical industry, car, ship accessories, etc. Mechanical property test method:all alloy steel pipes shall be checked for mechanical properties. The mechanical properties inspection methods
