Technical Data Sheet Bright AnnealingFor bright annealing to be effective, tube surfaces must be clean and free of foreign matter. The annealing atmosphere must be relatively free of oxygen (if a bright result is desired). This is accomplished by removing nearly all gas (creating a vacuum) or by displacement of oxygen and nitrogen with dry hydrogen or argon. ForFile Size: 367KBPage Count: 6
Jun 01, 2019 · Then the factors affecting the brightness of the stainless steel tube annealing furnace are as follows: First, whether the annealing temperature reached the specified temperature. Stainless steel annealing furnace generally adopt solid solution heat treatment, which commonly called "annealing", and the temperature rang is 1040~1120 (Japan standard).What is the purpose of bright annealing?The purpose of bright annealing process for stainless steel. The process of bright annealing of stainless steel aims to obtain sufficient metallographic structure by eliminating the work hardening and, on the other hand, to obtain an oxide free bright surface.See all results for this questionWhat is the annealing temperature of austenitic steel?Annealing temperature should be noticed depending on different stainless grades, commonly Austenitic steels annealing temperature is at least 1040 degree, soak time is not important. high temperature must be required to have brighter appearance. Heating is done as fast as possible, slow heat results in oxidation.See all results for this question

Especially for smaller dimensions it helps to fulfill the required high quality material properties. Quality Check and CertificationKeeping stainless steels stainless - The FabricatorStainless steel's corrosion resistance is due to a thin, chromium-rich, transparent oxide film on the surface1. This protective film develops when more than 10.5 percent of chromium is present in the alloy and when the gas or liquid environment the stainless steel is exposed to provides oxygen to its surface. Under these conditions, the surface is passive, or resistant to corrosion. Failure to develop and maintain this passive film renders the surface active, or possessing corrosion resistance similar to conventional sSee more on thefabricator bright annealing gas steel tube steels
