Product specification and description
Coil testing is an important link to ensure the quality and performance of steel coil products, usually including the following aspects of testing:
Appearance quality: mainly check the surface flatness of the steel coil, surface defects (such as scratches, pits, rust, etc.) and thickness deviation. These defects not only affect the appearance of the steel coil, but also may affect its performance.
Dimensional accuracy: involves the measurement of the thickness, width and length of the steel coil. These dimensions must meet the relevant standards and customer requirements to ensure the suitability of the steel coil for subsequent processing and use.
Chemical composition analysis: The chemical composition of steel coil directly affects its mechanical properties and corrosion resistance. Therefore, rigorous chemical composition testing is required to ensure that the product complies with the specified requirements.
Mechanical properties test: including tensile strength, yield strength, elongation and other indicators of the test. These tests are done with equipment such as tensile testing machines to ensure that the steel coil has sufficient strength and stability.
Surface coating inspection: For coated products such as galvanized steel coils, it is necessary to check the coating thickness, adhesion and other indicators to ensure the quality and anti-corrosion performance of the coating.
In addition, depending on the purpose and special requirements of the steel coil, other special tests may also be required, such as corrosion resistance testing, impact toughness testing, etc.
Material introduction
Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties.
Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%. Most commonly, the phrase "alloy steel" refers to low-alloy steels.
Strictly speaking, every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type) and nothing else (excepting negligible traces via slight impurities); these are called carbon steels. However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Common alloyants include manganese (Mn) (the most common one), nickel (Ni), chromium (Cr), molybdenum (Mo), vanadium (V), silicon (Si), and boron (B). Less common alloyants include aluminium (Al), cobalt (Co), copper (Cu), cerium (Ce), niobium (Nb), titanium (Ti), tungsten (W), tin (Sn), zinc (Zn), lead (Pb), and zirconium (Zr).
The following is a range of improved properties in alloy steels (as compared to carbon steels): strength, hardness, toughness, wear resistance, corrosion resistance, hardenability, and hot hardness. To achieve some of these improved properties the metal may require heat treating.
Although alloy steels have been made for centuries, their metallurgy was not well understood until the advancing chemical science of the nineteenth century revealed their compositions. Alloy steels from earlier times were expensive luxuries made on the model of "secret recipes" and forged into such tools as knives and swords. Modern alloy steels of the machine age were developed as improved tool steels and as newly available stainless steels. Today alloy steels find uses in a wide array of applications, from everyday hand tools and flatware to highly demanding applications such as in the turbine blades of jet engines and in nuclear reactors.
