Japanese standard angle steel 125 75 10 Japanese standard angle iron material and standard
1. Overview. Japanese standard angle steel is a kind of angular steel, which is widely used in construction, bridges, vehicle manufacturing and other fields. Among them, the 125*75*10 specification of Japanese standard angle steel is a more commonly used model, and its material and standard have an important impact on its quality and performance. This article will introduce in detail the materials and standards of Japanese standard angle steel 125*75*10.
Second, the material. The material of Japanese standard angle steel 125*75*10 is usually Q355B or Q355D, which is a low-carbon alloy structural steel. The advantages of this material are that it has good strength, toughness and corrosion resistance, and at the same time has good welding performance. In addition, according to the need, the surface can also be galvanized, painted and other treatments to improve its corrosion resistance and aesthetics.
3. Standards. The standard of 125*75*10 of Japanese standard angle steel mainly follows the Japanese industrial standard (JIS G3192-2016), which clearly stipulates the size, shape, weight, strength, toughness and other indicators of Japanese standard angle steel. At the same time, during the production process, a series of inspections and tests are also required to ensure that its quality and performance meet the standard requirements. Specifically, here are some of the main technical requirements:
1.Size and shape.
The size and shape of the Japanese standard angle steel 125*75*10 should comply with the provisions of Table 1. Among them, the edge width and edge thickness are important factors affecting its bearing capacity and stability, which must be strictly controlled. At the same time, indicators such as bending angle and twisting degree also need to be controlled within a certain range to ensure their installation and use effect.

2.Weight and weight permissible deviation.
The weight and allowable deviation of the weight of the daily standard angle steel 125*75*10 shall be in accordance with the provisions of Table 2. In actual production, due to the influence of various factors, the actual weight may deviate from the standard weight. However, in order to ensure its effectiveness and safety, it must be controlled within a certain range.
