ASTM A479 specification covers hot and cold-finished Stainless Steel Bar, including rounds, squares, and hexagons, and hot-rolled or extruded shapes such as angles, tees, and channels for use in boiler and pressure vessel construction. Four grades of the stainless steel are available which includes austenitic, austenitic-ferritic, ferritic, and martensitic grades. Mechanical properties such as tensile strength, yield strength, elongation, and hardness shall be determined for the specimens subjected to normalized, tempered, annealed, and quenched conditions. The austenitic stainless steels shall be subjected to heat treatment and shall undergo corrosion test. The round bars rolling process takes place with placing the stainless steel in a analyzed continuous shape rolling mill which is released in the first eight rolling stands. Feed stock before the rolling process is controlled (dimensions, surface, number of melting) and then it is heated in a walking beam furnace according to the technology of heating the steel grade. When heated to the appropriate temperature, it is subjected to descaling operations generated by the heating process. The next stages are technological operations of rolling in individual stands. After the hot rolling process, the product obtained is cooled down to ambient temperature.
