1075 steel is considered to be high carbon grade steel. If corrosion is not expected to be a problem and if the material cost is significant component, 1075 carbon steel is a good, economical material choice. It is widely used for general spring application. GuangWeiYouLiang produce 1075 high carbon spring steel in both annealed condition in thickness ranges from 0.15mm to 3.00mm and tempered condition in thickness from 0.15mm to 2.50mm and width 2mm to 300mm.
Chemical composition of 1075 carbon steel: C% 0.72-0.80, Mn% 0.50-0.80, Si% 0.17-0.31, S% max 0.035, P% max 0.035
