Company OFAS is the leader in production of discs for disk harrows and seeders. Italian company uses steel grade 30MnB5 with high content of boron for production. Unlike other manufacturers of disks, OFAS buys only Swiss steel. This steel is known as the most qualitative in Europe, because of its mineral origin. OFAS does not use metal that was obtained after processing. Such spare parts are stonger, more durable and wear-resistant. Due to this, OFAS is the first-stage supplier of spare parts for manufacturers of agricultural machines in Germany.
