APM 9980 HOT ISOSTATIC PRESSED (HIP) PRODUCTS DATASHEET APM 9980 is a low carbon martensitic stainless steel. The grade is specially designed to combine high mechanical properties including toughness and improved corrosion resistance properties when compared to other martensitic stainless steels, like 13 Cr and 13 Cr 4 Ni grades. The alloy has been primarily designed to resist to erosion-corrosion or cavitation encountered in hydraulic applications. The alloy is also used for offshore structures and fluid/gas control systems where the combined mechanical and corrosion resistance properties are needed. Mining, cement plants, and hydraulic applications take also advantage of its combined abrasion-corrosion resistance properties. STANDARDS - ASTM: S165M - EN Number: 1.4418 - SS: 2387 CHEMICAL COMPOSITION (NOMINAL) % Chemical composition (nominal) % C Cr Mo Ni Datasheet updated 3/8/2018 8:59:39 AM (supersedes all previous editions) Balance Fe. FORMS OF SUPPLY Components can be supplied in a wide range of dimensions and shapes because of the flexibility provided by powder metallurgy and near net shape technology. The products are supplied in the in the quench and tempered condition. APPLICATIONS For any application requiring high strength, high hardness, and corrosion resistance similar to 304 stainless. Many applications can be found in fields like automotive, industrial, and others, where a combination of high mechanical properties and a good corrosion resistance is critical. APM 9980 is a martensitic stainless steel specially designed for those applications requiring high mechanical properties combined with improved corrosion resistance relative to traditional martensitic steels. MECHANICAL PROPERTIES Hot isostatic pressed components have isotropic properties, meaning the mechanical properties are similar in all directions. Mechanical properties at 20°C (68°F)

Fine isotropic microstructure of HIPed material vs. forged bar. Note micrographs show duplex material for illustration. CORROSION RESISTANCE Due to its high nickel, chromium and molybdenum content, and its low carbon concentration, APM 9980 has a good resistance to atmospheric corrosion. It has same resistance to seawater atmosphere, as 304 and higher 13% Cr grades. APM 9980 has a low resistance to...

work surfaces must be thoroughly cleaned before use. These precautions are necessary to avoid cross contamination of stainless steel by easily corroded metals that may discolor the surface of the fabricated product. MACHINING Martensitic-austenitic stainless steels such as EN 1.4418 are quite similar to duplex steels regarding machining. Machinability is of course dependent on heat treatment condition, if material is annealed or hardened and tempered. Machinability depends to a great extent on material hardness. COLD FORMING AND STRAIGHTENING The elevated strength and the pronounced work...
