Mn |
P |
S |
| ≤0.25% |
≤0.40% |
0.80% ~1.20% |
≤0.04% |
≤0.05% |
The production method of ASTM A36 includes a series of precise production processes, as follows: molten iron pretreatment, smelting, refining treatment, continuous casting, rolling, heat treatment, flaw detection, and finally, flaw detection of the steel plate to ensure its surface quality and Dimensional accuracy meets requirements.
The characteristics of ASTM A36 are mainly reflected in the following aspects:
1. Chemical composition: ASTM A36 has good weldability and toughness. ASTM A36 has a low carbon content, usually less than 0.25%. This chemical composition results in strong weldability and toughness.
2. Mechanical properties: ASTM A36 has excellent mechanical properties. Its yield strength is usually around 250MPa, and its tensile strength is between 400-550MPa. At the same time, its elongation and impact toughness are also very high, and it can maintain good performance in various environments and usage scenarios.
3. Processing performance: ASTM A36 has good formability and can easily perform processing operations such as cutting, bending and welding. This excellent processing performance makes ASTM A36 widely used in various application scenarios.
4. Corrosion resistance: ASTM A36 has good corrosion resistance and has certain resistance to most common corrosive media. This allows ASTM A36 to perform well in applications that need to withstand corrosive environments.
5. Comprehensive performance: The strength, plasticity and welding properties of ASTM A36 are well matched and suitable for a variety of application scenarios. Whether it is in the fields of construction, pidges, machinery manufacturing or petrochemical industry, ASTM A36 can provide reliable performance. ASTM A36 has a wide range of applications, mainly including the following aspects: ASTM A36 is widely used in the manufacture of building steel structures, pidges, towers, roof panels, wall panels and other building components. In pidge construction, ASTM A36 is used to manufacture large pidge structures, such as highway pidges, railway pidges, etc. Machinery manufacturing field: ASTM A36 is also commonly used in the machinery manufacturing field, such as manufacturing structural parts of machine tools, vehicles, ships, pressure vessels and other equipment. ASTM A36 is used to manufacture industrial equipment such as oil pipelines, storage tanks, and conveyor belt supports, as well as to produce various steel structural parts and components.
