Steel Knowledge

In the production process of carbon steel pipes, hot rolling and cold drawing are two common processes. There are significant differences between the two in production process, product performance and applicable occasions, and each has its own advantages and disadvantages and application fields. 1. Hot

45# Steel is a high-quality carbon structural steel with the following characteristics: 1. Good comprehensive mechanical properties: It has a certain balance of strength, hardness, toughness and plasticity. 2. Good machinability: It is relatively easy to perform cutting, forging, welding and other processing operations. 3.

The standards for welded steel pipes cover the respective specifications of different regions and countries to ensure the quality, safety and performance of the products. These standards are applied in major markets such as China, the United States, Europe and Japan. The following are common

Rebar is a kind of steel bar with longitudinal and transverse ribs, which is often used in reinforced concrete structures to enhance the tensile strength of concrete structures. Due to the ribs on its surface, rebar has a stronger bonding ability with concrete and can

The American Iron and Steel Institute (AISI) is an association of North American steel producers. AISI standards are mainly used to identify and classify steel, especially the chemical composition and mechanical properties of steel. The AISI system represents different steel grades, such as carbon steel,

DIN standard (Deutsches Institut für Normung, German Institute for Standardization) is a technical standard system for steel pipes and other materials in Germany. DIN standard is the national standard of Germany and is widely used in the manufacture of various materials and industrial products, including

JIS (Japanese Industrial Standards) provides systematic guidance for the production and application of steel pipes. JIS covers steel pipes made of a variety of materials, including carbon steel, stainless steel, alloy steel, etc. Each material is classified into different steel grades according to its chemical

ASTM (American Society for Testing and Materials) standards are widely used internationally, covering the chemical composition, mechanical properties, manufacturing process and other requirements of various materials. In the field of steel pipes, ASTM standards have specific specifications for different types of steel pipes. The following

Carbon steel material Q355 is a low-alloy high-strength structural steel in the Chinese standard (GB/T 1591-2018), which is widely used in buildings, bridges and other structural engineering. Q355 belongs to low-alloy high-strength structural steel. According to Chinese standards, it is a typical low-alloy steel suitable

API Standard is an industry standard developed by the American Petroleum Institute (API) and is widely used in the oil and gas industry. API Standard covers all aspects from exploration, production, processing to transportation and sales, ensuring the safety, reliability and compatibility of equipment and
