12.No. 5 Japanese standard channel steel 125*65*6 size specification standard.
12.No. 5 Japanese standard channel steel is a common steel, its model is 125*65*6, with a unique shape and size specification standard. Knowing its dimensional specification standards is essential for the proper use of this steel. This article will go into more detail about 12Dimensional specification standards for No. 5 Japanese standard channel steel to help you better understand and apply this steel.
I. 12The model and size of No. 5 Japanese standard channel steel.
12.The model of No. 5 Japanese standard channel steel is 125*65*6, which is a widely used steel. The size of this channel steel has the following characteristics:
1.The height is 125 mm, which is similar to the height of the domestic No. 8 channel;
2.The waist width is 65 mm, which is slightly narrower than the domestic No. 8 channel steel;
3.The leg thickness is 6 mm, which is slightly thinner than the domestic No. 8 channel.
II. 12Dimensional accuracy requirements of No. 5 Japanese standard channel steel.
In the process of manufacture and use, 12There are strict requirements for the dimensional accuracy of No. 5 Japanese standard channel steel. Depending on the application, the dimensional accuracy needs to meet the corresponding standards. In general, 12The dimensional accuracy of No. 5 Japanese standard channel steel should meet the following requirements:
1.Height: Permissible deviation of 3 mm;
2.Waist width: permissible deviation of 2 mm;
3.Leg thickness: The allowable deviation is 15 mm.
III. 12The weight calculation method of No. 5 Japanese standard channel steel.
12.The weight of the No. 5 Japanese standard channel can be calculated according to its size. Generally speaking, the weight calculation formula of channel steel is: weight = cross-sectional area density. Wherein, the cross-sectional area can be calculated according to the size of the channel steel, and the density is 785 grams cubic centimeters. Therefore, to calculate 12The weight of the No. 5 Japanese standard channel steel can be obtained by calculating the cross-sectional area according to its size and multiplying it by the density.
IV. 12The scope of application and precautions of No. 5 Japanese standard channel steel.
12.As a common steel, No. 5 Japanese standard channel steel is widely used in construction, bridges, vehicles and other fields. During use, the following points should be noted:
1.Choose the right model and size according to your needs;
2.Take care to keep the steel surface clean and smooth;
3.During processing and installation, relevant norms and standards should be followed to ensure safe and reliable use.
In conclusion, understand and master 12The size specification standard of No. 5 Japanese standard channel steel is essential for the correct use of this steel. In practical application, the appropriate model and size should be selected according to the need, and attention should be paid to following the relevant norms and standards to ensure safe and reliable use effect. At the same time, strengthening the inspection and maintenance of materials is also an important measure to ensure their service life.
