Forta LDX 2404®

Austenitic-ferritic stainless steel also referred to as duplex stainless steels, combine many of the beneficial properties of ferritic and austenitic steels. Due to the high content of chromium and nitrogen, and often also molybdenum, these steels offer good resistance to localised and uniform corrosion. The duplex microstructure contributes to the high strength and high resistance to stress corrosion cracking. Duplex steels have good weldability. All duplex grades have the maximum service temperature restricted to 250 or 325°C according to EN10028-7 or ASME II-D 2007 respectively. Outokumpu produces a range of duplex grades, LDX 2101®; 2304; LDX 2404®; 2205; 4501 and 2507.

LDX 2404®is a molybdenum-containing duplex stainless steel with high contents of chromium and nitrogen. The grade combines a higher mechanical strength than for other common duplex grades with a generally high corrosion resistance.These characteristics make

LDX 2404® well suited for optimal designs with respect to strength, reduced maintenance, durability and long-term cost efficiency.

Forta H400

Forta H400 has higher strength than standard Core 304/4301 and a lower nickel content, making it a cost-effective and lightweight austenitic product for the automotive industry. It has been used in automotive applications for over 10 years.

Forta H400 is an austenitic stainless steel, which belongs to the austenitic low-nickel CrMn stainless steel family, in which manganese replaces part of the nickel that is normally alloyed to CrNi standard grades. This variant has low carbon content. Due to its high nitrogen content, Forta H400 has increased mechanical strength. Forta H400 is optimized for strong work hardening on mechanical deformation.

The corrosion resistance of the austenitic CrMn grades is usually slightly below that of the austenitic CrNi standard grades. Forta H400 is used in applications where a combination of high mechanical strength and good formability, as well as corrosion resistance, is needed. Due to its strong tendency to work hardening, Forta H400 can absorb a high amount of energy during deformation. It can be delivered in the temper rolled condition with different strength levels.

Typical applications
  • Cross members
  • Strut domes
  • Bumpers

Therma 310S/4845

Austenitic heat resisting 4845 grade with very good oxidation resistance. This grade 4845 belongs to austenitic chromium-nickel stainless steel grades. A specific feature for 4845 grade is high chromium and high nickel contents, which make this grade suitable for use in high temperatures. A common feature of Outokumpu high temperature steels is that they are designed primarily for use at temperatures exceeding ~550 °C, i.e. in the temperature range where creep strength as a rule is the dimensioning factor and where HT corrosion occurs. Optimising steels for high temperatures has meant that their resistance to aqueous corrosion has been limited. All steels are austenitic, resulting in relatively high creep strength values.

Characteristic properties
• Good resistance to oxidation
• Good resistance to high-temperature corrosion
• Good mechanical strength at elevated temperatures

Typical applications

Outokumpu high temperature steels can be and have been used in a number of applications where the temperature exceeds 550°C, e.g. for equipment and components within:

  • Industrial furnace equipment
  • Oil industry equipment
  • Heat treatment baskets
  • Heat exchanges

Chemical composition

Therma 4724

Low-alloyed ferritic heat resisting grade with improved scaling resistance. Uncritical regarding embrittlement at service temperatures. Applied for e.g. furnace equipment, thermal boiler components, grids, burner nozzles, conveying parts, thermowells.

The high temperature (HT) ferritic stainless steels complement Outokumpu austenitic heat and creep portfolio. The main alloying element in the ferritic grades is chromium. Its positive effect on the scaling resistance is enhanced by silicon and aluminium. The characteristic properties are excellent resistance to oxidising and reducing sulphur containing atmospheres, good resistance to oxidation and high thermal conductivity with low thermal expansion.

4713 does not form brittle phases but should only be exposed to moderately corrosive atmospheres owing to its low chromium content.

4724 is a truly stainless high temperature grade with 13% chromium. It is not critical in terms of embrittlement. 4742 shows better scaling resistance than 4724 and can be subjected to reducing sulphur environments without risk. It is subject to 475°C embrittlement and grain coarsening at temperatures above 950°C. σ-phase may form after long time exposures to temperatures around 650°C.

4762 - with the highest chromium content- is the most resistant to reducing sulphurous gases. It is susceptible to the same embrittlement phenomena as 4742 whilst σ-phase forms during long exposures in the range 600°C to 800°C.

Typical applications

Outokumpu Stainless ferritic high temperature steels are mostly used in high temperature applications with sulphurous atmospheres and/or low tensile loads such as for installations within:

  • Furnace equipment
  • Thermal boiler components
  • Grids
  • Burner nozzles
  • Conveying parts
  • Thermowells
  • Chemical industry (drums)
  • Power industry (coal burners)
  • Metalworking industry (heat treatment boxes)

Coil service centers work as extended workbenches of our cold rolling mills and offer you proven benefits; delivery reliability, quality assurance and lot sizes to match any of your requirements.

Why cold-rolled coil, strip, and sheet?

Cold rolling occurs when the metal is processed through a cold rolling process below its recrystallization temperature increasing the material strength via strain hardening, also known as work hardening. An additional benefit to cold rolling is that the surface finish is improved while obtaining tighter tolerances compared to hot rolled products. After cold rolling, it is typical to recrystallize the material by annealing and remove the newly formed scale by pickling. Cold-rolled stainless steel products are an excellent choice because of

  • Great width selection in coils, strips and sheets
  • Excellent dimensional accuracy
  • Available in austenitic, ferritic, duplex and martensitic grades, with wide variety of special surfaces

 

Cold rolled coil, strip and sheet

A wide selection for a variety of use; our cold rolled coil, strip and sheet products are available in both heat- and corrosion resistant forms. In addition, their standard and special surface finishes provide a unique level of customization. These products come in the following stainless-steel types: austenitic, ferritic, duplex and martensitic. Lightweight yet strong, the cold rolled coil, strip and sheet products are fully recyclable and are versatile in application. 

The Outokumpu offering includes semi-cold rolled surface RAP®2E: it is cold rolled, heat treated, mechanically descaled and pickled. It is a relatively rough shot blasted finish with cold band dimensional tolerances. 

 

Expertise in production 

Outokumpu has the ability to produce coils up to two meters in width in Avesta, Sweden (with the exception of 72 inches, which is produced in in Calvert USA), as well as the most comprehensive thickness range.

Our strip products can be produced in a variety of widths, depending on the gauge required. Using the modern technology, an entire range of strip can be produced to the tightest tolerance. For thinner gauges and narrower strip refer to Outokumpu precision strip offering.

From complete control of the production process – beginning at Outokumpu’s own Kemi mine, the source of chrome used to produce stainless steel – to advanced production efficiencies, unmatched technical expertise and unwavering commitment to quality, Outokumpu delivers significant value to our customers.

We have an extensive coil service center network that operates as extended workbenches of our cold rolling mills and offer you proven benefits; delivery reliability, quality assurance and lot sizes to match any of your requirements.
