Thicknesses ranging from 0.3mm to 3.0mm of 'steel cookies' are currently enjoying their moment in the spotlight. Home appliance giants are rolling them into refrigerator exteriors, new energy vehicle manufacturers are pressing them into battery trays, and even smart lockers are using SPCD cold-rolled steel sheets for their designs. A workshop technician joked: 'Today's steel is like Gen Z, needing a smooth surface and high aesthetics while also being able to withstand pressure, tension, and fatigue, living a more intense life than us blue-colla...

Q235 carbon steel is a type of carbon structural steel, where 'Q' stands for yield point, and 235 indicates a yield strength of 235 MPa. It has high plasticity, toughness, and welding properties, and also performs well in cold stamping, with certain strength and good cold bending properties. This material is widely used across various fields. In the construction industry, it is commonly used for general-purpose parts and welded structures, such as rods, connecting rods, pins, shafts, screws, nuts, and other components that are not subject to...

First, about the annealing process of steel pipes The heat treatment process of heating the steel pipe to an appropriate temperature, keeping it warm for a certain period of time, and then slowly cooling it (generally cooling with the furnace) is called annealing. The essence of annealing is to heat the steel to austenitization and then transform it into pearlite. The structure after annealing is close to the equilibrium structure. 1. Purpose of annealing: (1) Reduce the hardness of steel, improve plasticity, and facilitate machining and col...

In modern construction, engineering and manufacturing, Stainless Steel Pipes are widely used, and their quality is directly related to the safety and durability of the project. As an important standard to ensure the quality of stainless steel pipes, the national standard wall thickness specification plays a vital role in practical applications. The national standard wall thickness specification refers to the relevant standards and requirements for the wall thickness of stainless steel pipes. By standardizing the wall thickness of stainless...

To enhance the corrosion resistance and service life of Carbon Steel Pipes, surface treatment technologies are of vital importance. Common treatment methods include galvanizing, coating and lining techniques. Hot-dip galvanizing involves immersing the steel pipes in molten zinc liquid to form a dense zinc-iron alloy layer, which can effectively isolate air and moisture. It is widely used in construction, agriculture and civil fields, such as the framework of greenhouse sheds and fire protection pipelines. The coating technology...
