As a representative of martensitic precipitation hardening stainless steel, 13-8PH (UNS S13800) is renowned for its superior performance: through a dual melting process of vacuum induction and consumable electrode remelting, its yield strength can reach over 1100MPa, and its tensile strength can reach up to 1600MPa. It also exhibits excellent resistance to pitting corrosion in chloride environments, comparable to 304 stainless steel. This material is widely used in extreme conditions such as aerospace landing gear components and oil exploration downhole tools. Its production must strictly comply with the stringent requirements of AMS-5629J standard regarding chemical composition (chromium 12.25%-13.23%, molybdenum 2.00%-2.50%, etc.) and mechanical properties.
The exported stainless steel pipes not only meet performance standards but also undergo customized processing to address the unique characteristics of cross-border transportation. Shuangzhong Intelligent, considering the application scenarios in the Washington, D.C. area, provided anti-corrosion packaging and heat treatment process reports to ensure the products maintain stable mechanical properties even at 316℃. This order represents a significant achievement in the company's "technology going global" strategy, validating its import/export qualifications and end-to-end service capabilities in the international market.
