58FC-G-035-10 - Techniweld .035 Hardfacing MIG Wire 10lb Spool Gas Shielded

Techniweld 58FC-G Hardfacing Flux-Cored Wire (.035" - 10lb Spool)

The Techniweld 58FC-G is a specialized gas-shielded flux-cored wire designed for hardfacing applications where severe abrasion and moderate impact are the primary concerns. Packaged in a convenient 10-pound spool, this 0.035-inch diameter wire is ideal for maintenance and repair operations that require a durable, wear-resistant surface overlay. Unlike standard joining wires, this alloy deposits a martensitic steel structure that achieves a high hardness rating, typically ranging between 55 and 60 HRC (Rockwell C), making it an excellent choice for protecting metal surfaces from earth, sand, and gravel abrasion.

This wire is formulated to run with external shielding gas, compatible with either 100% CO2 or a 75% Argon / 25% CO2 mixture. The gas shielding assists in producing a stable arc, reducing spatter, and ensuring a clean, high-quality deposit compared to some open-arc alternatives. The 0.035-inch diameter offers versatility, allowing operators to perform hardfacing on thinner edges or smaller components where precise control is necessary, while still providing high deposition rates typical of flux-cored processes. It is commonly used in the agricultural, mining, construction, and dredging industries.

Key Technical Specifications:

• Diameter: 0.035" (0.9mm)
• Spool Weight: 10 lbs (4.54 kg)
• Hardness: Approx. 55-60 HRC
• Shielding Gas: 100% CO2 or 75/25 Ar/CO2
• Polarity: DCEP (Direct Current Electrode Positive)
• Machinability: Non-machinable (Grind only)

When applying Techniweld 58FC-G, it is recommended to limit the deposit to two or three layers to prevent cracking due to the high hardness and internal stresses of the material. If a thicker buildup is required, a buffer layer of a softer, more ductile material should be applied first. This product is an essential consumable for workshops dedicated to extending the lifespan of heavy machinery and reducing replacement costs for ground-engaging tools.
