Iso 559-77 Welded or Seamless Steel Tubes For Water Sewage and Gas

This document provides information on chemical composition, mechanical properties, and standards for various grades of welded or seamless steel tubes according to ISO 559-77. It lists the allowable ranges for elements like carbon, silicon, manganese, phosphorus, and sulfur in the chemical composition for grades TSO through TW9. It also outlines the minimum yield points and tensile strengths for each grade. Finally, it shows the corresponding JIS, ASTM, DIN, NF, and ISO standards for different grades.
