We purely focus on high strength aluminum alloys such as 7075 7475 7055 7050 2024 2014 2124 aluminum tube bar profile. Ye Fong is the aluminum mill awarded NADCAP heat treating , NADCAP Nondestructive testing, AS9100, ABS, DNV, IS0 9001, ISO 14001 and provides customers with various aluminum alloy round drawn wire, round drawn rod, cold heading Annealing of cold rolled steel - Steel casting foundry USAStress relief:This stage takes place at a temperature around 480 C to 500C. During this stage, the atoms in the steel move around causing a reduction of internal stresses. 2. Recrystallisation:This stage takes place at a temperature around 500-550 C. Though the internal stresses are removed in the stress relief, new crystals are not formed.
