This alloy has a thermal expansion that closely matches vitreous potash-soda-lead glass. Soft Magnetic Alloys. The nickel-iron alloys also offer an interesting set of magnetic permeability properties, which have played an important part in switchgear and for direct current (dc) motor and generator designs.
Quench hardening of steel - Total Materia
Hardening of steel is obtained by a suitable quench from within or above the critical range. The temperatures are the same as those given for full annealing. The soaking time in air furnaces should be 1,2 min for each mm of cross-section or 0,6 min in
What is alloy sensitization? - Rolled Alloys, Inc.
The alloy is heated to a temperature of about 1950 to 2050 F and then water or air cooled. Another control technique for preventing intergranular corrosion involves incorporating strong carbide formers or stabilizing elements such as niobium or titanium in the stainless steels.
