Böhler diamondspark 54 MC E70C-6M Seamless Metal-Cored Wire
Description
Seamless metal-cored wire for root passes, pipe and automation
The Böhler diamondspark 54 MC is a seamless metal-cored wire for single- or multipass welding of carbon, carbon-manganese and similar steels, including fine-grain steels, with Ar-CO2 or pure CO2 shielding. Böhler Welding lists high yield strength, good weldability, excellent bead appearance, low spatter and exceptional mechanical properties at low temperatures (-70 °F) in the as-welded condition or after post-weld heat treatment. The wire is described as well suited to automated applications and to root pass welding of pipes and butt joints, and it can be used in sour gas applications (HIC tested to NACE TM-0284, SSC values on request). The classification is AWS A5.18 E70C-6M H4.

The mechanical values in the data sheet are typical values only; no minimums are printed for this wire, so any toughness requirement has to be proven in the project procedure test.
Base materials and selection
The listed base metals are shipbuilding steels A, B, D, E and A 32 to E 36, ASTM A 106 Gr. A to C, A 181, A 283, A 285, A 350 Gr. LF1, A 414, A 501, A 513, A 516 Gr. 55 to 70, A 573, A 588, A 633, A 662, A 711, A 841 and API 5L Gr. B to X65. Metal-cored wire produces little slag, so it suits multipass robotic and mechanised welding where interpass cleaning time matters, and it is a common choice for pipe roots. For rutile flux-cored alternatives that need slag removal but are easier out of position, see the and the

Process and ordering notes
Confirm in the enquiry the shielding gas (Ar-CO2 or CO2), diameter, packaging, weld position and process (manual, mechanised or robotic), and the toughness temperature and certificate type required. Ask for the matching approval certificate if the project needs a class society or TÜV document beyond what is printed.
Documents and quotation

About brand
Böhler Welding is the welding consumables brand of voestalpine Böhler Welding, part of the voestalpine group, with a portfolio that covers stick electrodes, TIG rods, solid wires, gas-shielded and self-shielded flux-cored wires and submerged-arc wires and fluxes. The company states more than 100 years of experience. Seven Star LLC, an independent supplier in Muscat, lists Böhler Welding consumables and welding machines, including pipeline electrodes, and sources Böhler Welding consumables for fabricators and pipeline contractors.
Böhler Welding product groups
Beyond the consumables above, Böhler Welding lists strip cladding, wire arc additive manufacturing, metal powders, arc spraying cored wires, ceramic weld backing, brazing consumables and welding automation such as orbital welding and collaborative robots. The pipeline range includes cellulosic FOX CEL electrodes and basic vertical-down FOX BVD electrodes for large-diameter line pipe.
Ordering Böhler Welding consumables: what we need
Give the product name, the AWS or EN classification, the diameter and length, and the packaging you need. For pipeline electrodes also state the pipe grade, wall thickness, welding position and whether sour-service test values are required, because the Böhler Welding data sheets note that some test values are available on request.
