boiler steel Introduction
Boiler steel used to manufacture mainly refers to the superheater, the main steam pipe and boiler heating surface of the fire chamber materials used. Performance requirements for boiler steel is mainly good weldability, certain high temperature strength and alkali resistance, corrosion resistance and oxidation. Commonly used in open-hearth smelting boiler steel has a low carbon killed steel or mild steel smelting furnace, carbon content Wc at 0.16% -0.26% range. When you apply pressure boiler manufacturing pearlitic heat resistant steel or austenitic heat-resistant steels. In recent years, the construction of boilers using ordinary low-alloy steel, such as 12 Mn, 15 manganese vanadium, molybdenum, niobium and manganese 18 and so on.
Boiler steel are classified according to purpose and can be subdivided into the name of the boiler tube steel pipe, including direct contact with flames or smoke tube boiler heating surface and not in direct contact with flame or smoke a joint boxes and steam piping, etc. and a steel drum with two types of marriage. Boiler boiler pressure components are critical components, high security requirements, their working conditions in addition to withstand high internal pressure and internal media corrosion and erosion, the boiler heating surface tubes still need to withstand the external flame or smoke erosion , wear and corrosion of harmful gases. The boiler tubes and boiler plate material should be in addition to the special requirements of each.
