Description

WELD STAR 385 STAINLESS STEEL 2.4MM TIG FILLER RODS – 5KG

AWS A5.9 – ER 385

A 5kg pack of 2.4mm Weld Star 385 stainless steel TIG welding rods. Constructed from super austenitic stainless steel and designed specifically for use in environments where a high resistance to stress corrosion cracking is necessary.  Ideal for use with base metals of a similar composition. Excellent resistance against pitting and crevice corrosion attacks. Also available in 1.6mm and 3.2mm.

The chemical composition of this filler wire has excellent properties including good levels of resistance to sulphuric solutions which is achieved by additional amounts of Copper (Cu). High levels of Nickel (Ni) provide increased material strength, particularly at high temperatures. The Chromium (Cr) content ensures good wear resistance.  Molybdenum also plays an important role by improving the resistance of corrosion in acid based solutions.

Due to its exceptional resistance to the effects of corrosion it is used extensively in acid and chemical fertiliser industries, pulp and paper plants and applications where seawater is a factor.

Features & Benefits
  • Excellent resistance stress corrosion cracking
  • Good levels of wear resistance
  • Available in 1.6mm, 2.4mm and 3.2mm
  • Impressive material strength even at high temperatures
  • Increased resistance to corrosion from the presence of acid based solutions
  • Ideal for use with base metals of a similar composition

 

What is Stress Corrosion Cracking?

Stress corrosion cracking is produced by the combined influences of tensile stress and the presence of a corrosive environment. Fractures will either occur at the intergranular grain boundary level or at transgranular level through the material grains.

The three main causes of stress cracking corrosion are the type of material, tensile stress and environment.  The bullet points below expand on how these factors increase this form of corrosion:

    • Material – It is important to remember that different materials will have better or worse capacity to withstand the effects of this issue.  Therefore, choosing the correct materials for your application is a key consideration
    • Tensile Stress – When material is either affected by residual stress or is alternatively subjected to an applied amount of stress or pressure from an external agent.
    • Environment – Plays an extremely important role since environmental factors such as the presence corrosive chemical elements. which can result in the increase of stress corrosion cracking.
Industries & Applications
  • Chemical Industry
  • Paper & Pulp Processing Plants
  • Marine Applications
  • General Repair & Maintenance

In Conclusion

As shown above, Weld Star 385 stainless steel TIG filler rods have excellent resistance to the wide ranging effects of corrosion.  Particularly in environments where stress corrosion cracking (SCC) presents a significant issue.   Increased amounts of Nickel (Ni) enhance material strength even at high temperatures, Chromium (Cr) content gives good wear resistance, and the use of Molybdenum (Mo) heightens the weld materials capacity to resist the effects of corrosion caused by acid based solutions.
