Q355GNH weathering steel is a kind of atmospheric corrosion resistant steel, which has better corrosion resistance than A573Gr.65 plate export, ordinary carbon steel by adding less alloy elements. Q355GNH weathering steel has been widely used in container, railway vehicle, bridge, building and air preheater which need to be resistant to atmospheric corrosion. Q355GNH weathering steel is characterized by the addition of less Cu, P, Cr, Ni and other alloy elements in the steel, so that a dense amorphous spinel type oxide layer with a thickness of about 50-100μm is formed between the rust layer and the base metal, which can prevent oxygen and water from penetrating into the steel matrix, slow down the development of corrosion to steel materials, and improve the atmospheric corrosion resistance.
Advantages of A573Gr.65 plate export, stainless steel: 1. Chemical properties: the chemical and electrochemical corrosion resistance of stainless steel is the best in steel, second only to titanium alloy. 2. Physical properties: stainless steel has good heat resistance, high temperature resistance, low temperature resistance and even ultra-low temperature resistance. Stainless steel can work safely at - 270℃ - 400℃ for a long time. No matter at high or low temperature, no harmful substances will be precipitated, and the stainless steel material properties are quite stable.
The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for A573Gr.65 plate export.
Pressure vessel steel plates are mainly used for manufacturing pressure vessels and other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of pressure vessel steel plates ranges from normal pressure to 320kg / cm2 or even 630kg / cm2, and the temperature ranges from - 20 °C to 450 °C. In addition to certain strength, good plasticity and toughness, pressure vessel steel plates must also have good cold bending and welding properties. Q245R, Q345R, 14Cr1MoR, 15CrMoR, A573Gr.65 plate export etc. are common pressure vessel steel grades.
