All products we supply to our customers are heat treated by our internal capacities, while meeting strict quality criteria for microstructure and hardness. The process of heat treatment of forgings is constantly monitored and each production batch is thoroughly checked in our laboratories for characteristics defined by the customer. The products are delivered to customers without scales, any need for shot blasting is provided by STEM devices.
