SS500 steel plate Cold bending performance and heat treatment

SS500 steel plate is a kind of hot rolled steel plate with high strength and plasticity, belonging to the low alloy and high strength steel series. The steel plate is made by smelting and rolling and belongs to low alloy high strength steel. SS500 steel plate, its advantages are high strength, good plasticity, strong toughness, suitable for use in harsh conditions. SS500 steel plate is used in machinery manufacturing, construction engineering and other fields, with good toughness and high impact toughness. SS500 steel plate is mainly used for making structural parts that bear impact load when the force is small and the section size is simple and the shape is complex and the size is large.

SS500 steel plate has excellent cold-bending performance. In the bending process, the cross section deformation of the bending member is mainly composed of the matrix, the plastic deformation of the metal and the inelastic deformation. The plastic deformation of metal mainly includes two forms: one is bending at room temperature; The other is bending at high temperatures. When bending, stress concentration occurs within the metal, resulting in plastic tensile or compressive stress, resulting in the steel's ability to resist cold bending. At present, it is mainly used in steel structure manufacturing and bridge components, pipelines and pipe fittings, etc., while it is mainly used in bridge components and building structures abroad.

1. The cold-bending performance of SS500 steel plate generally requires that the bending Angle is not more than 5° (or as required);

2. If the cold-bending performance is required to be good, the basic mechanical property index of the material should be indicated at the time of delivery;

3. The cold-bending properties of hot-rolled and cold-formed steels shall conform to the corresponding standards;

4. Cold-bending parameters shall be indicated in the contract.

SS500 steel plate with different chemical composition and heat treatment methods can produce different properties of products. SS500 steel plates can be produced under special heat treatment processes to meet specific use requirements. Good weldability, welding joints can be heat treated at low temperature, thus improving the fatigue life of materials. The welding parts and heat affected zone are the best hot working areas, and the workability of steel is good.

SS500 steel plate is low alloy high strength structural steel, generally has high hardenability and good low temperature toughness. According to its composition design can obtain higher strength, plasticity and toughness, better meet the requirements of special applications. Such as in Bridges and ship structure commonly used in the manufacture of Bridges, hulls, barges, etc. SS500 steel plate is mainly used for manufacturing needs to have high strength and does not allow the existence of cracks.
