Most of the marine grade KD32 hull steel plate steel materials used in industrial boilers are carbon steel materials. In a narrow sense, the boiler steel refers to the special steel used for manufacturing industrial boilers and power station boilers, mainly including pressure vessel steel, anti-oxidation steel and hot strength steel. Some of them are carbon steel, most of them are medium and low alloy steel, and a few are high alloy steel marine grade KD32 hull steel plate. In a broad sense, the boiler steel includes all the steel used to manufacture industrial boilers and utility boilers.
Special boiler steel is derived from carbon structural steel, marine grade KD32 hull steel plate. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.
Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for marine grade KD32 hull steel plate and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
marine grade KD32 hull steel plate, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of marine grade KD32 hull steel plate and No. 20 steel is 7.85kg/cm3
