Kinsey Piping is one of the prominent supplier and trader for Alloy 904L Pipes, where the aluminium addition allows for the formation of a continuous homogenous self-repairing subscale. These Stainless Steel 904L Seamless Pipes may be hot-worked in the temperature range 1200 Degree C to 900 Degree C (2190 Degree F to 1650 Degree F), followed by water quenching or rapid air cool. As with our Stainless Steel 904L Welded Pipes, do not attempt to form in the 600 Degree C – 800 Degree C (1100 Degree F – 1500 Degree F) temperature range. Do not heat these Stainless Steel 904L EFW Pipes, or any other alloy, with a torch to bend it, because the lack of temperature control will often result in cracking. Chromium (25 %) supplemented with aluminium (2.2 %) and micro – alloying addition (0.1 %) yttrium in our Stainless Steel 904L ERW Pipes form a very thin protective oxide scale. The addition of yttrium in these Stainless Steel 904L Round Pipes improves the adhesion and spalling resistance of the chromium and aluminium oxide scales. For heavier joints in our Stainless Steel 904L Square Pipes, it is recommended to use gas from Air Gas which was designed to reduce the likelihood of weld solidification cracks. For GTAW welding of these Stainless Steel 904L Rectangular Pipes, the use of Argon and Nitrogen for the shielding gas is suggested to minimize the likelihood of weld solidification cracking.
