Low-temperature-resistant angle steel is a kind of building structural steel specially used in low-temperature environments. Usually, low-temperature impact tests are used to test whether its performance meets the requirements for low-temperature resistance. The following are some common low temperature resistant angle steel introductions:
1. Specification: 20*20mm-250*250mm, thickness: 3mm-35mm.
Material: Q235B, Q345B, Q345C, Q345D, etc.
Product use: Mainly used to manufacture building structures in low temperature environments, such as low temperature storage tanks, bridges, ships, offshore platforms, etc.
2. Specification: 40*40mm-200*200mm, thickness: 3mm-20mm.
Material: Q235B, Q345B, Q345C, Q345D, etc.

The above are the specifications and materials of some common low-temperature-resistant angle steels. The actual product types and specifications will vary from manufacturer to manufacturer, and the specific selection should be determined according to the use requirements. Low temperature resistant angle steel has good toughness and strength in low temperature environment, can effectively prevent brittle fracture and failure caused by low temperature, and has important application value. In addition to common specifications and materials, there are some other issues that need attention, as follows:
1. The low temperature performance of low temperature resistant angle steel needs to be verified by low temperature impact test to ensure that it meets the requirements of low temperature applications. Generally speaking, the low temperature impact value of low temperature resistant angle steel should be greater than or equal to the specified standard.
2. The production of low-temperature-resistant angle steel needs to comply with the corresponding standards and specifications, such as national standards GB/T 1591, GB/T 11263, etc., to ensure the quality and performance of the product.
3. The surface of the low temperature-resistant angle steel should be smooth and flat, without cracks, scale and other defects, so as to ensure its service life and safety.
4. When purchasing low-temperature-resistant angle steel, you should choose the appropriate specification and material according to the actual use environment and needs, so as to achieve the best use effect.
In short, low temperature resistant angle steel is a special building structural steel, suitable for construction and engineering in low temperature environment, with good toughness and strength. When selecting and using, it is necessary to pay attention to relevant standards and specifications to ensure its quality and performance, and to avoid failures and safety accidents caused by inappropriate materials.
