Sleeman
Engineering, a division of Bradken UK Ltd, suppliers of
Compass® steel armour plate are the leading manufacturers of
wear resistant castings whose products are specified by
power generation, defence, mining, quarrying and engineering
companies throughout the world.
Compass steel armour plate is produced to the highest
quality standards. B555 ballistic armour and B300 blast
armour are low-alloy quenched and tempered steel. B555
ballistic armour plate, with its low cost / penetration
resistance ratio and multi-strike protection capability, is the ideal solution for light armouring problems and B300
blast armour plate, with its lower hardness and increased
ductility and toughness is recommended for the blast
protection of vehicle floors and static blast doors.
For military and
civil protection, Sleeman Compass B555 and B300 is designed
for use for armouring vehicles, static equipment, marine
installations, general light armouring solutions and static
blast proof doors. The armour can be used for:
Bradken provides
a comprehensive technical design service, and CAD
manufactured finished profiled components, formed, machined
or fabricated to customer requirements, as well as supplying
prime plate sheet. Using submerged plasma arc profiling,
thermal stress is reduced.
Their specialised and extensive production facilities have a
capacity of 9200 tonnes per year, and are supported by a
range of the latest inspection and testing equipment and a
continuing programme of research and development designed to
ensure that the Company remains in the forefront of casting
technology.
COMPASS® BALLISTIC ARMOUR STEEL PLATE
Their B555 ballistic armour and B300 blast armour steel is
designed to give consistent performance in a plate that can
be cut, drilled, formed and machined and has excellent
welding properties. Compass steel armour plate can be
supplied from stock in thicknesses from 3mm to 45mm,
ballistically certified, as prime plate or cut and worked to
customer's specifications in Sleeman's own workshops.
Compass steel armour plate undergoes ballistic testing at Sleeman's own UK MoD approved 50m range.
Compass B555 is a low-alloy steel armour plate with
strength, hardness and toughness properties above ISO
6831/1V-1970 and US Mil-S-46100B-1977 requirements.
Extensive ballistic testing and experience have shown
Compass B555 steel armour plate to be 25% to 33% superior to
conventional armour (US specifications Mil-A-12560 or
similar). It more than meets the requirements of the high
hardness armour plate specifications (US Mil-S-46100B-1977)
both in regard to hardness and toughness. Moreover it has
exceptional multi-hit capability.
VEHICLE ARMOURING KITS
Sleeman can supply armour in kit form for armoured vehicle
assembly line; or as complete conversion kits for saloon
cars (including transparent armour), which can be fitted in
any commercial workshop.
Compass steel armour is used by the UK MoD and by
manufacturers of armoured vehicles around the world. The
company has been assessed and registered by the UK MoD as
operating quality procedures in accordance with AQAP 4.
Compass armour is also used on naval ships for protection of
magazines, electronic equipment and other sensitive areas;
and also on advanced military aircraft where it affords
protection for the pilot and critical controls. Compass B555
steel armour plate is also suitable for earth moving parts
of military support vehicles. It may also be used for
emergency-fabricated replacement high-strength cast steel
gear casings, turrets, treads etc.
LIGHTWEIGHT STEEL ARMOUR FOR VEHICLE BALLISTIC PROTECTION
The ballistic protection / weight as well as cost /
penetration ratios of Compass B555 are superior to that of
normal armour plate. Hence it is particularly suitable for
lighter military vehicles, bullion security vans and
stationary guard posts.
Compass B555's ballistic and weight properties have allowed
designers to create not only lighter armoured personnel
carriers, but also armoured version of Land Rovers and
similar vehicles, tractors, buses and trucks, saloon cars
and ambulances, with full protection against small arms
attack without destroying the essential performance,
handling or appearance of such vehicles.
On armoured personnel carriers and scouting vehicles
experience has shown that thinner sections of Compass B555
steel armour can be used to achieve the same degree of
protection and allow an overall lighter vehicle to be
produced.
When the hull has a modern unitised design exterior suitably
shaped as deflection surfaces, such vehicles are capable of
defeating 7.62mm armour piercing rounds and provide greater
load carrying capacity, together with lower weight, fuel
requirements and tyre wear than a similar vehicle with
conventional armour.
PRODUCTS AND MARKETS
Firth Rixson Castings Limited produces fully heat-treated
and machined castings weighing from 1kg to 17000kg. All of
the company's sites are accredited to BS EN ISO 9002:1994.
Melting facilities consist of 10 high frequency melting
units from 500kg to six tonnes capacity. A total of eight heat
treatment furnaces, together with comprehensive machining
facilities, are available for the wide range of white iron
