The Chinese company successfully trial-produced high-strength martensitic precipitation hardening stainless steel PH13-8Mo bar. After inspection, all the indicators of the products meet the standard requirements and have been successfully delivered to customers. Martensite precipitation hardening stainless steel PH13-8Mo has good comprehensive properties, excellent fracture toughness, good transverse mechanical properties and stress corrosion resistance. It is widely used in aviation, aerospace, nuclear reactor and petrochemical industries, and has a broad market prospect.
In order to complete the trial production task, the technicians consulted a large amount of literature materials, and after sufficient argumentation, they planned from the aspects of raw material preparation, process route selection and process control points, and finally rationally formulated internal control standards and determined the processes of each process. Key points and a sufficient assurance plan for possible problems in the process. Finally, with the joint efforts of the relevant personnel, the production trial work of martensitic precipitation hardening stainless steel PH13-8Mo bar was successfully completed, and all the performance indexes of the products met the user requirements.
