ESAB OK 68.17 VP Stainless Steel Electrode
ESAB OK 68.17 VP is a versatile rutile-basic stainless steel electrode designed for welding martensitic steels, specifically the 13Cr4Ni-Mo type. Classified as E410NiMo-16 under AWS standards, it provides excellent mechanical properties, including high tensile strength and impact toughness. This electrode is ideal for use in environments where both strength and corrosion resistance are critical. For example, in high-pressure systems and heavy industrial machinery.
One of the key advantages of ESAB OK 68.17 VP is its ability to retain strength and toughness even after stress relief. This makes it an essential tool for industries like power generation, chemical processing, and equipment repair, where thermal cycling and exposure to harsh environments are common.
Key Features of ESAB OK 68.17 VP
- AWS Classification E410NiMo-16: Designed for welding 13% Cr and 4% Ni stainless steels, ensuring durable, high-strength welds.
- Excellent Toughness: Offers impact values of up to 45 J at -10°C and 40 J at -40°C, therefore ensuring reliability in cold environments.
- Post-Weld Stress Relief: Maintains tensile strength of 870 MPa and yield strength of 650 MPa even after an 8-hour stress relief cycle at 600°C.
- Corrosion Resistance: Designed for use in environments requiring corrosion-resistant welds, making it suitable for high-pressure systems.
- VacPac™ Packaging: Keeps electrodes dry and moisture-free, eliminating the need for re-baking and ensuring consistent weld quality.
