Technological properties
| Property | ||
|---|---|---|
| Application areas | Parts (pins, shafts, nozzles…) already made with 4112/4125 or 440B/C…High hardness re-quirements with a rather good corrosion resistance. | |
| Corrosion properties | The pitting corrosion resistance is better in the Tempered than in the Annealed condition, a feature that is similar for all high-carbon martensitic grades | |
| General machinability | Machinability: UGI® 4116N can be machined in the annealed condition. The machinability of UGI® 4116N is comparable to that of grade 1.4034 and significantly better than the machinability of grades 1.4112 and 1.4125 (AISI 440B / 440C). | |
| Heat Treatment | Solution annealing: For minimum hardness, grade 4116N should be treated at about 840°C a few hours followed by very slow cooling. The hardness thus obtained lies around 210 HV1kg. Solution Treatment and Quenching: Oil quench or air cooling should be carried out from a recommended solution temperature of 1050°C. Tempering: See below the curve that was obtained after a 10 minutes solution annealing treatment at 1050°C fol-lowed by air cooling. Tempering at 200°C achieves a good hardness / toughness balance. | |
| Hot forming | Forming: UGI® 4116N can be readily forged in the 950°C – 1200°C temperature range. Heating between 1180°C and 1200°C prior to forging is recommended, and forging temperatures should not decrease below 950°C. After forging, a slow cooling to room temperature is necessary, followed by annealing treatment, if a minimum hardness is required. | |

| Welding | Welding of grade UGI 4116N is only possible with special precautions, and should be avoided whenever possible. | |
