Deposition efficiency 95–97%. Uniform droplet transfer in spray arc with minimal spatter formation, good penetration, high resistance to porosity, and low hydrogen content (approx. 2 ml\/100 g weld metal). Minimal oxide residues allow for multi-pass welding without intermediate cleaning. Ideal for horizontal and flat fillet welds.\u003cbr\u003e\u003cbr\u003eStandard designations:\u003cbr\u003eEN ISO 17632-A: T46 4 M M21 1 H5 \/ T46 5 M M20 1 H5\u003cbr\u003eEN ISO 17632-B: T 49 4 T15-1M21A-UH5 \/ T 49 5 T15-1M20A-UH5\u003cbr\u003eAWS A5.18 \/ SFA-5.18: E70C-6M H4\u003cbr\u003e\u003cbr\u003eShielding gases: M20, M21 (Ar + 5–25% CO2) according to EN ISO 14175; current type DC+.\u003cbr\u003e\u003cbr\u003eBase materials: Steels with a yield strength of up to 460 MPa, including S235JR–S355JR, S235J0–S355J0, S450J0, S235J2–S355J2, S275N–S460N, S275M–S460M, P235GH–P355GH, P275NL1–P460NL1, as well as shipbuilding steels A, B, D, E, A 32–E 36.\u003cbr\u003e\u003cbr\u003eMechanical properties of weld metal (typical values, as-welded condition):\u003cbr\u003eRp0.2 approx. 490 MPa (≥460 MPa), Rm approx. 600 MPa (550–660 MPa), A approx. 28% (≥22%), Charpy V-notch impact energy at −40 °C approx. 95 J (≥47 J) with shielding gas M21; with M20 at −46 °C approx. 70 J (≥27 J).\u003cbr\u003e\u003cbr\u003eApprovals: TÜV (11163), DB (42.052.26), ABS, BV, DNV, CWB, LR, CE.\u003cbr\u003e\u003cbr\u003eNote: All information is based on the manufacturer's data sheet diamondspark 52 MC (03\/2025, voestalpine Böhler Welding).\u003c\/p\u003e","brand":"Böhler","offers":[{"title":"Default Title","offer_id":53862150635786,"sku":"52308","price":139.59,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0538\/6295\/7252\/files\/voestalpine-bohler-welding-schweissdraht-schweissdraht-bohler-emk-6d-k300-15kg-spule-sg2-g3si1-29893831917764_65756f93-bf26-400f-a76b-36c010868bc0.png?v=1692015223","url":"https:\/\/primewelding.live\/en\/products\/fulldraht-bohler-diamondspark-52-mc","provider":"PrimeWelding","version":"1.0","type":"link"}
