EN16T Alloy Steel
Known as a commercially popular ‘all-rounder’, EN16 (605M36T) is a low alloyed manganese-molybdenum through-hardening steel. Offering high strength and tensile characteristics, EN16 displays similar mechanical properties to EN8 but benefits from improved frictional wear, shear loading, and shock resistance. EN16 is considered to be a viable alternative to other steel specifications containing chromium and nickel. EN16 (605M36T) also offers excellent ductility and is readily machinable.

Applications
Commonly used for general engineering applications EN16T is suitable for applications such as high tensile shafts, bolts and nuts, gears, pinions spindles and the like.
Analysis
| Carbon | 0.30-0.40% | Sulphur | 0.050% max |
| Manganese | 1.30-1.80% | Phosphorous | 0.035% max |
| Molybdenum | 0.20-0.35% | ||
| Silicon | 0.10-0.35% |
Annealing
Heat slowly to 640-660°C. Cool in air.
Hardening
This steel grade is commonly supplied ready heat treated. If further heat treatment is required annealed EN16 should be heated slowly to 840-870°C and after adequate soaking at this temperature quench in oil. Temper as soon as tools reach room temperature.
Tempering
Heat carefully to a suitable temperature selected by reference to a tempering chart or table. Soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in air. Tempering between 250-375°C is not advised as tempering within this range will seriously reduce the impact value.

Heat Treatment
Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of alloy steel.
