Product specification and description
Steel rod inspection involves several aspects to ensure that its quality and performance meet standards. The following are some common steel rod inspection items and methods:
Appearance quality inspection: through naked eye observation, magnifying glass or microscope to check whether there are cracks, inclusions, pores and other defects on the surface of the steel rod.
Dimensional accuracy testing: Measuring the diameter, length and other dimensions of steel rods to ensure that they meet relevant standards and customer requirements.
Chemical composition analysis: Through spectral analysis or other chemical methods, the chemical composition of the steel rod is analyzed to ensure that its main components meet the requirements.
Metallographic structure analysis: The metallographic structure of the steel rod is observed by metallographic microscope to evaluate the rationality of its heat treatment process and processing technology.
Tensile test: This is one of the most commonly used tests for steel properties. The yield strength, tensile strength and elongation of steel can be obtained by tensile test.
Hardness test: used to determine the hardness of steel, the common hardness test methods are Brinell hardness test, Rockwell hardness test and Vickers hardness test.
Impact test: used to determine the impact resistance of steel, through the impact test can understand the performance of steel under impact.
In addition, steel rod testing also includes hydrogen embrittlement testing. Hydrogen embrittlement is a serious inherent defect of steel, which may lead to brittle fracture of steel. Hydrogen embrittlement detection methods include hydrogen pressure method and slow strain method.
These inspection items and methods are used together to comprehensively evaluate the quality and performance of steel rods to ensure their safety, reliability and effectiveness in applications. Please note that the specific testing items and standards may vary due to the use of steel rods, material type, manufacturing standards and other factors, so in practical applications, the appropriate testing methods and standards should be selected according to the specific situation.
Material introduction
Stainless steel, also known as inox or Corrosion Resistant (Stainless) Steel (CRES), is an alloy of iron that is resistant to rusting and corrosion. It contains at least 10.5% chromium, usually nickel, and may also contain other elements, such as carbon, to obtain the desired properties. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen.
The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products.
The biological cleanability of stainless steel is superior to both aluminium and copper, and comparable to glass. Its cleanability, strength, and corrosion resistance have prompted the use of stainless steel in pharmaceutical and food processing plants.
Different types of stainless steel are labeled with an AISI three-digit number. The ISO 15510 standard lists the chemical compositions of stainless steels of the specifications in existing ISO, ASTM, EN, JIS, and GB standards in a useful interchange table.
