25.4x1.65mm 19.05x1.65mmS32760 S31803 S32750 S31500 ASTM A789 A789M Seamless Ferritic Austenitic Stainless Steel Tubing
1. Scope
This specification covers grades of nominal wall thickness, stainless steel tubing for services requiring general corrosion resistance, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures.
The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Within the text, the SI units are shown in brackets. The inch-pound units shall apply unless the M designation of this specification is specified in the order.
Keywords:Corrosive Service Applications - Duplex And Super Duplex
Stainless Steel - Seamless Pipes And Tubes - Stress Corrosion
Cracking - Welded Pipes And Tubes
Size Range: OD: 6-89mm, WT: 1-8mm, Length: 5.8m/6m, maximal 11.8m

High pressure, low & medium pressure boiler steel pipestubes
are suitable for making
super-heaters, re-heaters, water wall, and economizer in
large-scale power plant.
Flattening Test – One flattening test shall be made on specimens
from each end of one finished tube, not the one used for the
flaring test, from each lot.
Flaring Test – One flaring test shall be made on specimens from
each end of one finished tube, not the one used for the flattening
test, from each lot.
