Tests Required for High-Frequency Welded Steel Tubes - Chemical Composition Analysis

The chemical composition of high-frequency welded steel tubes has a significant impact on their performance, hence the necessity for chemical composition analysis. This analysis is typically conducted through either chemical analytical methods or instrumental analytical methods, such as infrared C-S analyzers and direct-reading spectrometers, which are used to determine the content of elements like C, S, Si, Mn, P, Cr, Mo, Ni, and others in the steel tubes.
