Bright annealing （BA) is a part of stainless steel annealing process which is performed under reducing atmosphere or vacuum protection. The heating process gives the surface resistance to oxidation and a certain brightness.

Duplex Steel BA Tube， combines the advantages of austenitic and ferritic stainless steels offering approximately twice the yield strength of conventional austenitic grades. The BA finish further enhances the surface quality making Duplex BA tubes ideal for demanding service conditions.

Hastelloy C-276 BA Hastelloy C-276 (UNS N10276 / EN 2.4819) is the most widely used nickel-chromium-molybdenum alloy often called the "universal" corrosion-resistant alloy. It offers exceptional resistance to a wide range of aggressive chemical environments including oxidizing and reducing media and is resistant to the formation of grain boundary precipitates in the weld heat-affected zone.

Biopharmaceutical BA tubes are manufactured with stringent control over surface cleanliness dimensional accuracy and material integrity. The bright annealing process is carried out in a protective atmosphere (high-purity hydrogen or hydrogen-nitrogen mixture) preventing oxidation and eliminating the need for acid pickling which avoids the risk of hydrogen embrittlement. The resulting surface is

Bright annealing (BA) is a part of stainless steel annealing process which is performed under reducing atmosphere or vacuum protection. The heating process gives the surface resistance to oxidation and a certain brightness. A thin wall BA tube is a bright annealed tube whose wall thickness is small relative to its outside diameter — down to 0.2mm (0.008") at Harmonypipe. The thin wall constructi

Bright annealing (BA) is a part of stainless steel annealing process which is performed under reducing atmosphere or vacuum protection. The heating process gives the surface resistance to oxidation and a certain brightness. A thick wall BA tube is a bright annealed tube with a heavy wall relative to its outside diameter — up to 12mm*4mm (0.157") at Harmonypipe. The heavy wall construction deliv
