What is the q345r steel application

Our company's q345r steel power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the q345r steel utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

q345r steel, A335 P22 is a steel grade of American Standard boiler tube, and the executive standard is ASTM A335 / A335M, which is chromium molybdenum high temperature ferritic steel for boiler and superheater. A335P22 alloy pipe is mainly used as heating surface pipe of low and medium pressure boiler (working pressure is generally not more than 5.88 MPA, working temperature is below 450℃); A335P22 alloy pipe is also used as economizer, superheater, reheater and petrochemical industry pipe of high pressure boiler (working pressure is generally above 9.8MPa and working temperature is between 450℃ and 650℃).

SA516 gr.60 boiler plates are primarily intended for use by pressure vessel fabricators and manufacturers. And, physical and chemical characteristics of the boiler quality plates make these a popular choice in the industries. SA516 gr.60 boiler steel plates are made up of premium quality raw materials by the use of the latest machinery and are therefore of robust built. Also, these plates q345r steel are repellent to corrosion and therefore is long-lasting and can also be used in different environments for a long time without any deterioration.

Water cutting machine is called water knife for short, that is, water is used as knife. High pressure water jet cutting technology can perform any curve cutting process on any material, q345r steel included. The heat generated in the cutting process will be immediately taken away by the water jet without harm. Material, no need or easy to reprocess after cutting, safety and environmental protection, faster, faster, more efficient.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with q345r steel, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

The gas cylinder steel is one of our featured products. The pickled LPG steel is available. We supply gas cylinder steel coil, gas cylinder steel sheet and gas cylinder q345r steel steel plates.
