  • How to choose a supplier of precision stainless steel strips?

    When choosing a precision stainless steel strip supplier, you can consider the following key factors: Quality Control: Choose suppliers with strict quality control systems and high quality standards. They should be able to provide products that comply with international standards such as ASTM (American Society for Testing and Materials), JIS (Japanese Industrial Standards), DIN (German Industrial Standards), etc.

  • Why does stainless steel plate expand when heated?

    Stainless steel plates expand when heated, mainly due to the physical phenomenon of thermal expansion. The specific reasons are as follows: 1. Intensified molecular motion: When the stainless steel plate is heated, the atoms or molecules inside the metal will gain more thermal energy, causing their motion to intensify. According to the principles of thermodynamics, as the temperature rises, the average kinetic energy between molecules increases, which causes the interaction force between atoms to change, the distance between atoms to increase, and the overall volume of the metal to expand.

  • Matters needing attention in bending processing of stainless steel sheet

    The thicker the stainless steel sheet, the greater the bending force required, and as the thickness of the plate increases, the margin of bending force should be larger when selecting bending equipment. Stainless steel has poorer thermal conductivity than ordinary low-carbon steel, and the extension The rate is low, resulting in a large deformation force required;

  • What factors does the corrosion resistance of stainless steel coil depend on?

    The corrosion resistance of stainless steel coils mainly depends on the following factors: Alloy composition: Different types of stainless steel contain different alloying elements (such as chromium, nickel, and molybdenum), which affect their corrosion resistance. For example, 316 stainless steel is more corrosion resistant because it contains molybdenum.

  • How to judge the quality of stainless steel foil?

    To judge the quality of stainless steel foil, you can consider the following aspects: Surface finish: Observe the surface finish of the stainless steel foil. The surface of high-quality stainless steel foil should be smooth and have no obvious scratches, dents or oxidation spots.

  • High performance stainless steel strip application areas

    High-performance stainless steel strips are widely used in many fields due to their excellent mechanical properties, corrosion resistance and high temperature resistance. Here are some of the main application areas: 1. Aerospace Engine components: used to manufacture turbine blades, gas turbine components, etc., requiring high temperature strength and corrosion resistance. Structural parts: used for aircraft structures and shell materials, requiring high strength and light weight.
