Principal Design Features of AMS 5630/AMS 5618

This is a high carbon martensitic stainless with moderate corrosion resistance good strength and the ability to obtain and keep excellent hardness (Rc 60) and wear resistance.

Applications of AMS 5630/AMS 5618

Ball bearings and races, gage blocks, molds and dies, cutlery, valve components, knives and measuring instruments.

Machinability of AMS 5630/AMS 5618

Best machined in the annealed condition. Tough, stringy chips can be best handled by the use of chip breakers. Carbide or ceramic tooling is recommended.

Welding of AMS 5630/AMS 5618

This alloy is not commonly welded due to its tendency to air harden. If it must be welded, preheat to 500 F (260 C) and post weld treat at 1350-1400 F (732-760 C) for 6 hours followed by a slow furnace cooling to avoid cracking. Use similar filler metal and high heat inputs during operations.

Hot Working of AMS 5630/AMS 5618

Pre-heat to 1400 F (760 C), then bring slowly up to 1900-2200 F (1038-1204 C)before proceeding. Do not work this material below 1700 F (927 C). Cool material slowly after working and once at room temperature, anneal fully.
