The inch-pound units shall apply unless the M designation of this specification is specified in the order 2. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

When the final heat treatment is in a continuous furnace, or when heat treated condition is obtained directly by quenching after hot forming, the number of tubes of the same size and from the same heat in a lot shall be determined from the prescribed sizes of the tubes.

Mechanical tests such as tension test, flaring test for seamless tubesflange test for welded tubeshardness test, and reverse flattening test shall be performed on the steel tubing.

If, by any chance however small it may bethe products fail to satisfy the customers, we act on our product replacement scheme to ensure that they receive better. Lean Duplex Steel – e. The high chromium, molybdenum and nitrogen contents of provide corrosion resistance superior to common stainless steels, such as, L and L in most environments and Citizen Metals has been actively involved in ensuring the best quality of the same to our clients.
