Yes, hot rolled steel can be bent. However, the degree to which it can be bent depends on a number of factors, including the thickness of the steel, the radius of the bend, and the type of steel being used. In general, thinner steel and larger bend radii are easier to work with and can be bent more easily without cracking or breaking. It’s also important to note that the specific properties of the steel, such as its strength and ductility, can affect how easily it can be bent without damage.
Stainless steel strips and coils are used in a wide range of industries and the duty drawback rate for exporting these products from China is an important factor for suppliers of hot rolled stainless steel strips to consider. The rebate rate for stainless steel strip exported in coil form with a width of 600 mm or less is 13 percent. However, if the product is exported after processing, there are two ways to do this. The HS-CODE for strips and coils is different and the diameter point is set at 600 mm. If the product is exported as coils with a diameter over 600 mm, the rebate rate is 9%.
To ensure the best rebate rate, suppliers must carefully consider the size and shape of their stainless steel products. If suppliers want to export as strips, they need to ensure that the width is under 600mm, and if suppliers want to export as coils, they should keep the diameter under 600mm. This will help the suppliers to get the higher rebate rate of 13%. If the coil diameter is more than 600 mm, suppliers can still export the product, but they will receive a lower rebate rate of 9%.
It is worth noting that suppliers can also choose to use the coil-to-strip method to receive a 13% rebate on strip exports. This involves processing the coil and slitting it to the required width prior to export. With proper attention to these details, suppliers can maximize their rebates and ensure that their products remain competitive in the global marketplace.
