ASTM1045 has many similarities with domestically produced CN/GB 45# steel in terms of application, mainly used for manufacturing parts and mechanical components that can withstand high loads, including the production of prototype parts in various new product development stages, such as sheet metal stamping prototypes and steel CNC machined prototype parts.
Application area
Mechanical manufacturing: Both are commonly used to manufacture various mechanical components such as gears, shafts, connecting rods, etc., which can withstand heavy loads and impact loads.
Architecture: In the field of architecture, they can be used to manufacture the building structural components and steel bars, enhancing the stability and load-bearing capacity of building structures.
Automobile manufacturing: In automobile manufacturing, they are widely used in frames, carriages, engine parts including prototype parts and mass production parts, etc.
Aerospace: Due to their excellent mechanical properties and machinability, they are also used in the manufacturing of precision components in the aerospace field.
Petrochemical industry: In the field of petrochemicals, they can be used to manufacture equipment such as pipelines and containers, which can withstand the corrosion and erosion of high temperature and high-pressure oil and gas.
Chemical composition and performance differences
Chemical composition: The chemical composition of ASTM1045 includes elements such as carbon (C), manganese (Mn), phosphorus (P), sulfur (S), etc. The specific values may vary depending on different standards. The chemical composition of CN/GB 45# steel also includes elements such as carbon, manganese, silicon, and sulfur, but the specific content varies.
Performance difference: ASTM1045 typically has high strength and good toughness, making it suitable for manufacturing parts that can withstand high loads. 45# steel has been widely used in various fields due to its excellent mechanical and processing properties.
