Overview of stainless steel products manufactured by voestalpine Böhler Welding:

Stick electrodes for MMA

MMA welding is suitable for almost all weldable stainless steels and a broad range of applications. Characterized by great flexibility in all welding positions, MMA is widely employed for primary fabrication, on-site work and repair welding. The electrodes used for MMA are characterized by the coatings on the electrodes, which can be of several different types.

Electrodes offered by Böhler Welding are produced with a range of special coatings for different applications with focus on optimizing efficiency and weld metal quality in each application. They are named according to the chemical composition of the coatings. The coatings of Böhler Welding’s electrodes fall into three groups: basic electrodes, rutile electrodes and rutile-acid electrodes. Depending on the type of coating used, the electrodes have different welding characteristics and produce different weld metal properties.

Böhler Welding cored wires are available on wire basket and plastic spools. They are precision layer wound and have excellent feeding characteristics. All stainless steel flux-cored wires are vacuum-packed in moisture resistant aluminized bags for maximum protection. Inside, the spool is contained by a plastic bag. This makes protection of the wire easier when not used.

The standard weights and packaging are given below. For fully automated applications, smaller spool packaging is offered.

Success Stories

FOXcore 625-T1

Acting in a highly competitive market, Serimax is constantly working on solutions to strengthen their global offer for pipeline welding. The next step in this development was to increase the productivity by replacing manual welding processes for CRA pipes in 5G position with automated FCAW and a bug system. As existing products did not meet the requirements, a new flux-cored wire was needed.

For their objective to become the first pipeline welding company able to offer a welding solution with an automatic welding bug system and a 625 type flux-cored wire for the welding of cladded pipes in position 5G, they turned to voestalpine Böhler Welding for support.

Key Targets:

According to the requirements Serimax had communicated based on their experience and customer specifications, the following product features were crucial:

  • Good weldability in all positions
  • 5G welding with constant parameter setting
  • Good slag detachability
  • No defects (especially porosity)
  • Fulfilling mechanical properties

The team of Global R&D Joining Cored Wires developed a wire with better weldability, slag removal and resistance to pore formation than other wires on the market.

FAQs

Austenitic stainless steels are the most common stainless steels. The austenitic group covers a wide range of steels with great variations in properties. Corrosion resistance is normally the most important of these.

Corrosion resistance: Austenitic stainless steels are characterized by excellent corrosion resistance. Many austenitic stainless steels have a low carbon content (< 0.030%). This makes them resistant to sensitization (i.e. predisposition to intergranular corrosion) engendered by the brief thermal exposures associated with cooling after annealing, stress relieving or welding.

Mechanical properties: Austenitic stainless steels are primarily characterized by their excellent ductility, even at low temperatures. Ferrite-free, fully austenitic stainless steels with a high nitrogen content, and austenitic stainless steels with a ferrite content up to 8 FN, have very good impact toughness and are therefore highly suitable for cryogenic applications.

Weldability: Austenitic stainless steels are generally easy to weld and do not normally require any preheating or post-weld heat treatment.  With respect to weldability, the filler metals used for welding these steels can be divided into two groups:

  • Fillers with min. 3% ferrite (e.g. types 19 9 L / 308L, 19 12 3 L / 316L and 19 9 Nb / 347)
  • Fillers with zero ferrite (e.g. austenitic type 20 25 5 Cu N / 385 and nickel-base fillers such as Ni 6625 / NiCrMo-3 and Ni 6059 / NiCrMo-13)

More details about corrosion resistance, weldability and mechanical properties of austenitic stainless steels can be found in our special Stainless Steel Welding Manual. Please contact your sales representative or contact us (contact form) for more information.

Ferritic stainless steels are, in principle, ferritic at all temperatures. They are normally alloyed with 13 – 18% chromium and low levels of the austenite formers carbon and nickel.

Corrosion resistance: Modern ferritic stainless steels (e.g. type 430) have a low carbon content. Their resistance to atmospheric corrosion, organic acids, detergents and alkaline solutions is good (comparable to that of austenitic type 304L). The resistance of ferritic stainless steels in chloride containing environments and strong acids is moderate.

Mechanical properties: Compared to the common austenitic grades, ferritic stainless steels have higher yield strength, but lower tensile strength.

Weldability: The weldability of ferritic stainless steels depends heavily on their chemical compositions. Due to the generally high (C+N)/Cr ratio, which led to martensite formation and embrittlement in the heat-affected zone (HAZ), the “old types” of steel had rather poor weldability. Modern ferritic stainless steels are entirely ferritic at all temperatures. Consequently, weldability is much improved.

More details about corrosion resistance, weldability and mechanical properties of ferritic stainless steels can be found in our special Stainless Steel Welding Manual. Please contact your sales representative or contact us (contact form) for more information.

Duplex stainless steels have a two-phase microstructure with approximately 50% austenite and 50% ferrite.

Corrosion resistance: Due to the high content of chromium, nitrogen and additions of molybdenum, duplex stainless steels are characterized by their high resistance to pitting and crevice corrosion. All modern types of duplex stainless steels are produced with low carbon content. This and the favorable microstructure, make them resistant to sensitization to intergranular corrosion.

Mechanical properties: Duplex stainless steels combine the properties of ferritic and austenitic steels. The yield strength is up to twice as high as for austenitic steels with similar pitting corrosion resistance and the ductility is higher as compared to ferritic steels.

Weldability: Although somewhat different to ordinary austenitic stainless steels such as 304L and 316L, the weldability of duplex stainless steels is generally good. Duplex stainless steels are typically alloyed with 0.10 – 0.27% nitrogen and solidify with a fully ferritic structure with austenite nucleation and growth during cooling.
