ASTM AISI ISO Hot Cold Rolled 201 202 304 316 410 420 430 Round Tube Polished Precision Line Seamless Galvanized/Stainless Steel Pipe Industry for Construction
The hot and cold rolled steel industry plays a crucial role in construction, providing the materials necessary for the creation of buildings, bridges, and other infrastructure. To ensure the quality and reliability of these materials, various standards have been established by organizations such as ASTM, AISI, and ISO. These standards are essential in maintaining consistency and safety in the industry.
ASTM, or the American Society for Testing and Materials, is a globally recognized organization that develops and publishes technical standards for a wide range of materials, including steel. Their standards cover various aspects of steel production, such as chemical composition, mechanical properties, and testing methods. By adhering to ASTM standards, manufacturers can ensure that their steel products meet the required specifications and are suitable for use in construction projects.
a Labels are for information and assistance in ordering.
b Nominal linear masses, threaded and coupled (Column 4) are shown for information only.
c The densities of martensitic chromium steels (L80 Types 9Cr and 13Cr) are less than those of carbon steels; The masses shown are therefore not accurate for martensitic chromium steels; A mass correction factor of 0.989 shall be used.
d Mass gain or loss due to end finishing; See 8.5.
e Drift diameter for most common bit size; This drift diameter shall be specified in the purchase agreement and marked on the Pipe; See 8.10 for drift requirements.
Similarly, AISI, or the American iron and Steel Institute, is another prominent organization that sets standards for the steel industry. AISI standards focus on the designations and classifications of different types of steel, providing a common language for manufacturers, engineers, and other professionals in the industry. These standards help ensure that the right type of steel is used for specific applications, taking into account factors such as strength, corrosionresistance, and formability.

ISO, or the International Organization for Standardization, is a globalstandard-setting body that develops and publishes international standards for various industries, including steel. ISO standards provide guidelines for the production, testing, and quality control of steel products. These standards are crucial in promoting international trade and ensuring that steel products meet the
