(2) Inspection methods: The commonly used standard inspection methods for the above chemical ingredients are GB223, JISG1211-1215, BS1837, BS Manual 19, г с т 22536, etc.
Processing Technology Of Q355D Steel U channel bar
In use, it is required to have good welding, riveting and comprehensive mechanical properties. The raw material billet for channel steel production is carbon bonded steel or low alloy steel billet with carbon content not more than 0.25%. Finished channel steel is delivered by hot working, normalizing or hot rolling. Its specifications to waist height (h)* leg width (b)* waist thickness (D) mm number, such as 100*48*5.3, that waist height is 100 mm, leg width is 48 mm, waist thickness is 5.3 mm channel steel, or called 10# channel steel. The channel steel with the same waist height, if there are several different leg width and waist thickness, also need to add a, B and C on the right side of the model to be distinguished, such as 25# A 25# B 25# C.
