SSAB - Oxelösund
 
SSAB Oxelösund AB, develops manufactures and markets heavy plate.

The plant of Oxelösund is located on the Baltic coast 110 km south of Stockholm and is a subsidiary of SSAB Svenskt Stål.

It is a full integrated steel works producing around 1.6 million tones of steel slabs each year.

High grade iron ore from Swedish mines ensures that we create the best conditions for the production of clean steel with low levels of inclusions and impurities.

The mill includes a coking plant, blast furnaces, LD-furnace, continuous casting, four high rolling mill, direct cooling, roller quenching and heat treatment facilities all of which give us complete control of the production process. These efforts have been matched by our Quality Assurance System which meets the toughest international standards including ISO 9001 and AQAP-1.

The new four high is the most modern and powerful mill in the world, with a rolling force of 10.000 tonnes, which enables the production of plates with improved properties and tolerances.

After heating to around 900oC, the plate is quenched to room temperature in our roller quenching equipment.

ARMOX

ARMOX armour plate has been used in many military and civilian applications throughout the world.
The plates are manufactured in thicknesses from 3 to 150 mm and in hardnesses up to 600 HB.

Further details on the different steel grades, weldability and fabrication are provided in special data sheets and brochures.
 

HARDOX

The sides and bottom of a concrete mixer are subjected to sliding wear. However, the wear applied to the bottom is at a higher pressure.
Even if the wear is relatively moderate, the useful life is important to the economics. In this case, HARDOX 400 has proved to be the most appropriate material.
For the best possible useful life, HARDOX 500 is used for the bottom of the mixer.

TOOLOX

TOOLOX 44 PREHARDENED TOOL STEEL		TOOLOX 33 PREHARDENED TOOL STEEL
Toolox 44 unique on the market		Toolox 33 superb advantage
The development of Toolox 44 is based on our other well-known products HARDOX and WELDOX. The flexibility of Toolox 44 opens up new perspectives to applications such as plastic moulding dies, swaging tools, wear mouldings, sheet metal press dies, and is excellent for long production runs and more complicated products with stringent quality requirements. Toolox 44 permits new, modern processes to be used for manufacturing tools. The higher machining costs are more than balanced by the guaranteed shorter manufacturing times, more consistent and stable material characteristics. In addition, a number of risk factors are abolished from the manufacturing process, such as the complete elimination of the risk of failure due to the hardening process.		Lower hardness makes Toolox 33 extremely easy to machine, and cutting speeds can be increased by 20-25% compared with traditional tool steel, W.nr. 1.2312. Combined with unique shape stability, this makes Toolox 33 an unassailable step ahead as a tool steel.
• TOOLOX 44 tool steel is pre-hardened at 45 HRC   and has excellent toughness. • High metallurgical purity and well-developed    casting technology result in an extremely   homogeneous material with good thermal   conductivity. The steel is superb for deep etching    and polishing. • TOOLOX 44 has good stability, machining and   welding properties. • TOOLOX 44 is an ideal substrate for surface   treatments such as nitriding and PVD.		• TOOLOX 33 tool steel has the same hardness (300   HBW) as W.nr. 1.2311/1.2312/1.2738,    P20, but is much tougher. • TOOLOX 33 is a homogeneous tool steel with a   low alloy content, annealed at a minimum of   600oC, resulting in excellent stability and   significantly improved machining properties. • TOOLOX 33 has high purity, making it superb for   etching, spark eroding and welding. It is also   easy to polish.

Toolox patent granted
The patent applies to the combination of steel chemistry and manufacturing process. Toolox is a more highly developed steel, which means that we deliver ready-made physical properties. This is a fundamental difference, compared with traditional steels, which are generally delivered with just a chemical specification. We measure and guarantee the hardness of the steel, its toughness, machining characteristics and homogeneity in its fully heat-treated state.
