Application
Steel grade 80 is used in the production of round and plate springs and parts operating under conditions of increased friction and under the influence of vibration loads; knives of earthmoving machines (bulldozers, scrapers, graders and motor graders), as well as other machine parts used in the hardened and tempered condition.
Welding
Steel grade 80 is not used for welded products.
