| Corrosion properties | FERROTHERM® 4828 is only slightly resistant to both oxidising and reducing sulphurous gases. In these media the use of FERROTHERM® 4828 is limited to temperatures below 650 °C. The corrosion resistance to carbonizing (up to 900 °C) as well as to nitrogenous, oxygen-poor gases is to be classified as medium. | |
| General machinability | Good - The formation of carbides in 1.4828 will result in increased wear of cutting tools. In addition to this, rapid work hardening and poor thermal conductivity require the use of adequate cooling and good quality cutting/machining tools. | |
| Heat Treatment | Optimal material properties are realised after solution annealing in the temperature range 1050 - 1150°C followed by rapid cooling in air or water. During operation and fabrication, the time spent in the temperature range 550 - 900°C must be minimised to avoid embrittlement, both chromium carbide precipitation and sigma phase formation. This embrittlement effect can be reversed by solution annealing the steel at a temperature in the range 1050 to 1100°C. | |
| Processing history | Solution Annealed | |
| Welding | Good - 1.4828 is weldable using all usual welding processes with no preheating being required. Low heat inputs should be used when welding, and post weld heat treatment is not necessary. Novonit 4829 and 4842 are suitable for use as filler materials when welding 1.4828. | |
