Tensileweld High-Strength Welding Rod – 36" Long, 1 lb Mini Pack (Select Size From Options Above)

High-strength, crack-resistant welding alloy for dissimilar steels, tool steels, high-carbon steels, and difficult-to-identify base metals.
Washington Alloy Tensileweld is a chromium-nickel high-strength welding alloy designed for demanding repair, joining, and build-up applications. Its unique austenitic-ferritic weld structure produces a dense, tough, crack-resistant deposit with excellent strength and ductility.

Tensileweld is especially useful when welding dissimilar steels or when the exact alloy of the base metal is unknown. It can be used on high-carbon steel, tool and die steels, stainless steel, spring steel, cast steel, manganese steel, clad steel, and other difficult-to-weld materials.

Package Information: This Arc-Zone listing is sold in 1 lb Mini Packs. Each rod is 36" long and is available in 1/16", 3/32", or 1/8" diameter.

Why Choose Tensileweld?

• High-Strength Weld Deposit: Designed for demanding repair and joining applications.
• Excellent Crack Resistance: Austenitic-ferritic weld structure helps produce tough, crack-resistant deposits.
• Dissimilar-Metal Welding: Especially useful when joining different steel alloys.
• Unknown Base Metals: A practical choice when the exact alloy content of the steel is not known.
• Heat, Corrosion & Abrasion Resistance: Weld deposits provide resistance to demanding service conditions.
• Impact Resistant: Useful for components exposed to shock or impact.
• Machinable Deposit: Finished weld metal can be machined when required.
• 36" Straight Rods: Long cut-length rods are convenient for controlled filler-metal applications.

Common Base Metals & Applications

Washington Alloy identifies Tensileweld for use with a broad range of difficult-to-weld metals, including:

• Dissimilar steels
• High-carbon steels
• Tool steels
• Die steels
• Stainless steels
• Spring and coil steels
• Manganese steel
• Cast steels
• Clad steels
• Unknown steel grades

Typical Repair Applications

• Steel castings
• Forgings
• Gears
• Tools and dies
• Shear blades
• Shaft rebuilding
• Agitator blades
• Turbine components
• Cast steel parts
• Structural repairs to tools and dies
• Buffer or underlay layers before hardfacing

Ideal for Dissimilar & Unknown Steels

One of the biggest advantages of Tensileweld is its ability to handle applications where the base metals are different or the exact material grade is unknown.

Its chromium-nickel composition creates a unique austenitic-ferritic structure with fine-grained delta ferrite in a rich austenitic matrix. This helps produce a strong, ductile, and highly crack-resistant weld deposit.

Typical Mechanical Properties

Weld Deposit Characteristics

• High deposition rate
• Smooth weld deposit
• Ductile weld metal
• Porosity-resistant deposit
• Shiny finished appearance
• Impact resistant
• Abrasion resistant
• Heat resistant
• Corrosion resistant

Recommended Welding Practices

Washington Alloy recommends cleaning the work area thoroughly before welding. Thick sections should be beveled as required.

For carbon and cast steels, a preheat of approximately 400°F may be recommended depending on the application.

• Maintain a short arc.
• Hold the electrode slightly inclined in the direction of travel.
• Use stringer beads.
• Peening is recommended for appropriate applications.

Note: Always follow the welding procedure appropriate for the specific base metal, joint design, material thickness, and application.
