Rail and marine

The complexity of today’s rail and marine industry increases as environmental and efficiency requirements drive advances throughout many components. Bodycote services and technical expertise advances with the industry, through changes in material utilisation as well as geographic shifts in production.

Diesel and gas engines

Across the spectrum of ship types, the engine is the vital centre and functions in a very harsh, caustic environment. Globally, Bodycote works with prominent engine producers and their sub-contractors to produce strong, reliable, lighter weight components that exhibit high corrosion resistance across a variety of new environmentally friendlier fuels.

Our services include a variety of heat treatment processes ranging from quenching, tempering, and nitriding of pistons, carburising of piston pins, induction hardening of camshafts, and case hardening of gear wheels.

• Gear wheels

Rail clips

Rail clips are used to hold rail tracks to the sleepers. Heat treatment processing and corrosion resistant coating gives these clips the strength to hold the tracks in place under several hundred tonnes of train whilst being flexible and able to withstand the effects of weathering for many years.

Steel bar or strip is cut into pieces and hot forged into shapes and sizes required. The clips are heat treated to harden the steel and increase the yield strength for flexibility. Finally, the clips are sherardized to improve their life expectancy against environmental corrosion, without reducing their fatigue life.

Diesel injectors

The development of low pressure carburising (LPC) is closely linked with the success of diesel injectors over the last 20 years. Today, the inner thin blind holes of an injector can be uniformly carburised large quantities to withstand over 2500 bar cyclical operating pressure over the entire lifetime of the injector. Bodycote low pressure carburises a variety of different fuel injector components and offers a great variation of the latest vacuum carburising technology for a perfect fit for challenging LPC applications.
