  • How to distinguish hot rolled coils from cold rolled steel coils

    First of all, we need to know what hot-rolled coils are and what cold-rolled coils are. 1. Hot rolled steel coils Hot-rolled coils are made from slabs (mainly continuous casting billets), which are heated and made into strips by rough rolling units and finishing rolling units. The hot steel stri...

  • The difference between galvanized square and rectangular pipes and ordinary square and rectangular pipes

    Square tube is a hollow square cross-section lightweight thin-walled steel tube, also known as steel cold-bent profile. It is a square section steel with a square cross-section shape and size made of Q235 hot-rolled or cold-rolled strip or coil as the base material, cold bending and then high-fre...

  • Introduction and uses of precision steel pipes

    Precision steel pipe is a high-precision cold-drawn seamless steel pipe with the characteristics of high accuracy in inner and outer diameter dimensions, wall thickness, good surface finish, smooth inner and outer surfaces, and no impact burrs. Precision steel pipes are usually made of carbon ste...

  • Application characteristics of I-beam

    Whether I-shaped steel is ordinary or light, due to the relatively high and narrow cross-sectional dimensions, the moment of inertia of the two main axes of the cross-section is quite different, so it can only be directly used for bending in the plane of its web. components or form them into latt...

  • Choose 2507 stainless steel or 316 stainless steel?

    Many people will be hesitant when choosing between 2507 stainless steel and 316 stainless steel. 2507 stainless steel has good corrosion resistance and can cope with acidic and alkaline environments, especially in seawater. In comparison, 316 stainless steel is also a high-quality material and i...

  • Characteristics of shipbuilding steel plate

    First of all, good toughness is the most critical requirement for marine steel plates. In addition, it requires high strength, good corrosion resistance, welding performance, processing and forming performance and surface quality. In order to ensure quality and sufficient toughness, the Mn/C of t...

  • The uses and classification of corrugated steel plates

    Corrugated steel plate is a steel plate with a corrugated surface made of stamped thin steel plates. Corrugated steel plates are made from cold-rolled or hot-rolled steel plates that have been formed multiple times, so they have high bending and tensile strength. Corrugated steel panels are widel...
