Inconel 625 - LCF Welding Rods
What is Inconel 625 - LCF Welding Rods ?
For low-cycle fatigue (LCF) applications where strength and flex are crucial, Inconel 625-LCF welding rods are used. The rods are used to join carbon steel, stainless steel and alloys based on nickel. They exhibit exceptional corrosion resistance especially in harsh and hot conditions. To meet customer needs, Parag Metals supplies Inconel 625-LCF welding rods in a range of sizes. Heat exchangers, chemical processing equipment, marine and aerospace all make extensive use of these rods. Size and quantity determine the price but we offer competitive pricing with assured stock availability.
Nickel (≥58%), chromium (20–23%) and molybdenum (8–10%) make majority of these welding rods with trace amounts of iron, niobium and other elements. They provide a high yield strength of 319 MPa and a tensile strength of 769.5 MPa. Excellent flexibility is demonstrated by the 63% elongation. The rods are resistant to wear and cracking under pressure and have good hardness (Rockwell B84). Between 1290°C and 1350°C is the melting point. With a density of 8.44 g/cm³ they are a good option for demanding applications.

Parag Metals supplies Inconel 625-LCF welding filler rods in different diameters and lengths. The diameter of our standard sizes is between 1.6 and 4.0 mm. Depending on the needs of the project different lengths are available. These rods are compatible with TIG and MIG welding processes. Because of their low carbon content, there is less chance of carbide precipitation when welding. Depending on their shape, they are also referred to as Inconel 625-LCF welding electrodes or Inconel 625-LCF welding filler wires.
Every batch of Inconel 625-LCF welding rod stock is tested for quality. We carry out tensile, bend, and chemical tests to ensure consistency and performance.
