1. Eddy current testing can be used instead of pressing test. The experimental working pressure or eddy current testing should meet the relevant requirements as compared with the sample specifications. The structural mechanical properties of stainless steel sheets are the key index values to ensure the application performance of honing tubes, which lies in the composition of the steel and the rules and regulations of the heat treatment process. In the steel pipe standard, according to different application regulations, the tensile properties and their strength and ductility index values are required, and there are also high and ultra-low temperature properties specified by customers.
2. The tensile strength of the honing tube: the force that the sample needs to bear when it is torn off during the whole process of pulling is derived from the in-situ stress obtained by the original cross-sectional area of the sample, which is called the tensile strength. N/mm2. It indicates the ability of metal composites to work against destruction under tensile strength.
