HIGH STRENGTH, HIGH TENSILE ENGINEERING 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.
The equivalent British specification for EN16 is 605M36T.
Machinability of EN16 (605M36T) is generally good although generous amounts of lubricant must be used throughout the machining process so that the steel does not rip in a similar fashion to EN8 under the same conditions. EN16 is more difficult to polish to a bright finish when compared with other engineering steels in the range.
EN16 can be hardened and tempered to the T condition. It is an ideal steel product for use in greater tensile strength applications achieving an overall strength of 770 N/mm² in normal use, although even greater strength can be achieved in smaller sections (up to 930 N/mm²). EN16 (605M36T) is highly suitable for use in most high load and shock applications – due to the ductility of the material it has plenty of ‘give’ before breaking and resists shearing / bending. EN16 does not suffer from temper embrittlement when heated. EN16 offers good hardenability up to a diameter of 39mm and can be welded although a precautionary pre / post heat treatment is advisable.
EN16 benefits from being a bright steel, cold drawn material because it offers good dimensional precision and a consistent cross-section; it is straighter and flatter than a comparable mild steel product, which in turn results in more cost-effective machining. When purchasing from Thames, we offer a depth of stock which is in closer incremental sizes. This means that you can purchase EN16 (605M36T) bright steel cold drawn bars from us that are closer to your finished size requirements. This is of considerable benefit to engineers and fabricators because in certain cases there may be no need to machine the material down. Our ability to cut bars to size using our in-house processing facilities also has a positive impact on the supply chain process, especially as we can offer rapid response times.
The only potential downside in the use of EN16 (605M36T) is the raw material cost which can be a little higher than other engineering steel products, however the steel's versatile characteristics make it a popular product.
EN16 (605M36T) is a versatile and popular engineering steel and therefore has a wide range of commercial applications. Examples include:
- Connection rods, pistons, high load couplings
- Hubs, bolts, shafts and axles
- Crankshafts, lifting gear
- Applications requiring high shock resistance
