The chemical composition is fundamental to the final performance and workability of steel pipes. We employ precise analytical instruments, such as Optical Emission Spectrometers, to perform rapid and accurate elemental analysis on raw materials from each heat or lot. We strictly control the proportions of key elements like carbon, silicon, manganese, phosphorus, and sulfur, and ensure the precise addition of micro-alloying elements. By verifying that the chemical composition fully meets standard specifications, we guarantee excellent mechanical properties and reliable weldability from the source, providing customers with consistently high-quality products.
