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.
Often referred to as the work horse grade, is the most widely used grade in the duplex family of stainless steels. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Duplex Steel and Pipe. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. We also provide Standard certificates like EN 3.

Work Item s – proposed revisions of this standard. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications.
The inch-pound units shall aetm unless the M designation of this specification is specified in the order.

The values stated in either inch-pound units or SI units are to be regarded separately as standard. The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy stress corrosion cracking resistance and high strength with those of an austenitic alloy ease of fabrication and corrosion resistance.
Duplex Steel Tubing Supplied to. It is also used by storage and transportation units of industries.
All tubes shall be furnished in the heat-treated condition in accordance with the specified temperature and quench conditions. A awtm rate of less than one percent has consolidated the claim. Duplex Stainless Steels Products Manufacturers.
Combining values from the two systems may result in nonconformance with the specification. Extended elevated temperature exposure can embrittle stainless.
All tubes shall be furnished in the heat-treated condition in accordance with the specified temperature and quench conditions. Heat and product analyses shall be performed wherein the steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, nitrogen, copper, and others. Duplex Steel Products: This covers grades of nominal wall thickness, stainless steel tubing for services requiring general corrosion resistancewith particular emphasis on resistance to stress corrosion cracking.
ASTM A Seamless Tube, ASTM A Welded Tubes, ASTM AM Duplex Tubing.
The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. A steel pipes piping. The material shall conform to the prescribed tensile and hardness properties.
