Iskenderun Iron and Steel Co. (ISDEMIR) is an integrated iron and steel facility, which produces both long and flat
products from production of iron ore. Wire rod, billet, coil with mill edge, slitted or trimmed coil and cut length plate
can be stated Isdemir’s product mix. Each of these products have different usage areas and customer expectations.
ISDEMIR has a wide range of application areas with the hot rolled flat products or long products, which are
expressed as wire rods-billets in order to respond to the customers', who operated in the industrial area and have
different demands and expectations, requests.
Some of the usage areas in long products are carbon steels for thin wire drawing, carbon steels for wire drawing, high
carbon steels, steels for mesh quality steel production, micro alloyed and non-alloyed high strength carbon steels for
wire-spring-rope production, steels for electrode and welding wire production, steels for bolt production, carbon
steels for nail, angle iron and profile production, steels for ship profile production, structure steels for angle iron and
profile production and sulphur alloyed high carbon steels etc.
Micro-alloy high-strength steel grades with excellent results in high-strength applications for flat products are
used in the production of wheel rim and chassis parts, which requires high strength and superior formability in
the basic input of automotive. Boiler steels suitable for use under high temperature and pressure are used in the
production of boiler and pressure vessels. Due to high formability, excellent weldability and toughness properties, tube
steels are used production of LPG tubes, which are exposed to high temperature and pressure. Medium and high
strength shipbuilding steels, which provide superior weldability and desired toughness values, are used in shipbuilding
(ship parts, keel etc.). General structural steels, which can be welded by conventional methods, provided ductility and
toughness optimization with guaranteed their mechanical properties, are mainly used in manufacturing of
construction and construction equipment, general construction plates, road and railway vehicles, storage tanks and
containers.

Manufacturing Practicing Code (MPC) is the key number which is consisted of 13 parameters and given to all the flat
(coil, plate) and long products (wire rod, billet) regardless of A1 or A2 quality manufactured in Iskenderun Iron and
Steel Co. (ISDEMIR). It underlies the basis of the follow-up systematic in the factory. These 13 parameters are aimed to
be increased till 28 parameters at a later time. All information about the product come under MPC which contains
customer demands which affect production and quality parameters in all phases from the stage of order placement
until delivery to the customer. These components identify the product and customer requirements. Isdemir
Production Management System (PMS), Production Control System and Long Product Sales System are
established on MPC from demand to shipment. Product type, steel grade, thickness/diameter, width, length,
domestic/export, size tolerance, length tolerance, type of packaging, outside/inside diameter, test report, special mark
and weight' create the infrastructure of MPC. All information in this code determine the production line where the
product has to be followed, processing parameters and tolerances in production lines. Thus, production and effective
control can be ensured accordingly. MPC which characterizes identification of customer demands, provides
continuity of the process and systematic along with PMS. ISDEMIR has 4 levels
of computing and automation system in the production process: The first three level is consist of machining, line
or division basis whilst fourth level provides production and control, gives production orders, allows quality control
and production monitoring functions generally in whole ISDEMIR. The
other name of Level-4 is Production Management System (PMS). Quality Design, Production Planning, Quality
Control and Production Monitoring etc. are sub-systems of PMS. Quality design, order acceptance, order entering and
order confirming are performed in the PMS. MPC is a necessary code on PMS because of the production planning
and the continuation of the product or semi-finished products to the next line. Therefore, MPC becomes the
main component of the Production Management System. It is a key that reflects the final product characteristics
consisting of a product code and a sequential number, expressed in 9 characters.
