Note: This table shows the limit service temperature of various materials. In actual selection, the lower and higher service temperature of the material should be determined according to the medium temperature range of the product. The lower operating temperature shall not be lower than the lower limit of the medium temperature range, and the higher operating temperature shall not be higher than the upper limit of the medium temperature range.
