Compared with hardness of NM450 sheet, 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.
Our company's logistics breaks through the perspective that the center of transportation service is ability, and emphasizes that the purpose of transportation service is customer first. Customer demand determines the content and mode of transportation service, while production is often small batch, diversified and consumer demand tends to be diversified. In the case of personalization, our logistics service also provides personalized service projects.
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 hardness of NM450 sheet.
