Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special A514 grade H alloy steel plate materials and specifications can be ordered in advance.
A299GrA steel plate is one of the materials widely used in boiler drums (steam drums) of coal-fired generator sets. Boiler plate A514 grade H alloy steel plate is mainly used in the head and shell of subcritical boiler drum products. Generally used for various welding parts whose working temperature does not exceed 400°C, such as boiler steam drums, pressure vessels, etc., which require the steel to have a high medium temperature.
Compared with A514 grade H alloy steel plate, boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.
The effect of Q345B alloy steel plate on the mechanical properties in the annealed state. The strengthening effect of alloying elements on steel in the quenched and tempered state, because it fully utilizes all four strengthening mechanisms. Martensite is formed during quenching, and carbide is precipitated during tempering, resulting in a strong second-phase strengthening, and at the same time greatly improving the toughness. Therefore, obtaining martensite and tempering it is an economical and effective comprehensive strengthening method for steel such as A514 grade H alloy steel plate.
EN 10025-2 steel includes S235 steel (S235JR, S235J0, S235J2), S275 steel (S275JR, S275J0, S275J2), S355 steel (S355JR, S355J0, S355J2, S355K2), S450 steel (S450J0).
