Chemical Composition of ISO 3183

Pandapipe has strict chemical controls on both types of ISO 3183 standard steel pipes, seamless and welded. The carbon content is 0.10% to 0.24%, balancing the hardness, strength and plasticity of the steel. Alloying elements help to improve the high temperature resistance and corrosion resistance of steel.
