| 1) Remark: The unstable austenitic microstructure of NIROSTA® H400 gives it a strong work hardening tendency, allowing significant strength increases to be achieved even after only minor deformation. These work hardening characteristics also give the material a high capacity for crash energy absorption. NIROSTA® H400s properties make it ideal for use in road and rail vehicles and provide wide scope for weight reduction. Corrosion resistance is comparable with steel 1.4301. In both as-delivered and welded condition, NIROSTA® H400 is resistant to intergranular corrosion. NIROSTA® H400 shows good hot and cold forming properties. All common cold forming processes can be used, such as bending, deep-drawing, spinning or profiling. However, the increased yield strength of the material requires higher forming forces than typical chromium-nickel steels, while a higher degree of springback must also be taken into account. Regarding the materials work hardening tendency and relatively low thermal conductivity, high-quality tool steel or hard metal tools should be used for machining. NIROSTA® H400 can be welded by all common techniques. When welding with filler materials, 1.4316 should be used for welds with similar materials and 1.4370 for welds with unalloyed steels. No preheating or post-welding heat treatment is required. |
