Steel boiler plates mainly refer to hot-rolled plates used to manufacture superheaters, main steam pipes and boiler firebox heating surfaces. Boiler steel plate is one of the most important materials in boiler manufacturing. Mainly refers to hot-rolled special carbon steel and low alloy steel used to manufacture important parts such as boiler shells, drums, header covers, hangers, etc. Heat-resistant steel medium-thick steel plate material.
The main materials are high-quality structural steel and low-alloy heat-resistant steel. Commonly used boiler steel is low carbon killed steel smelted in an open hearth or low carbon steel smelted in an electric furnace.
The carbon content Wc is in the range of 0.16%-0.26%. Since the boiler steel plate operates under medium temperature (below 350°C) and high pressure, in addition to high pressure, it also bears impact, fatigue load, and corrosion from water and gas. The performance requirements for boiler steel are mainly good weldability and cold bending properties. performance, certain high temperature strength and resistance to alkali corrosion, oxidation resistance, etc. Boiler steel plates generally operate under medium-high temperature and high pressure. In addition to high temperature and high pressure, it also has to withstand impact fatigue load and water vapor corrosion. The working conditions are poor, so the boiler steel plate must have good physical and mechanical properties. Workability ensures equipment safety.
Widely used in petroleum, chemical industry, power stations, boilers and other industries to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, hydropower stations High-pressure water pipes, water wheel volutes and other equipment and components.
