Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect welding consumables for 304 stainless steel.Employ AWS E308L or ER308L filler metals to maintain corrosion resistance and prevent carbide precipitation.
Allowing excessive heat input during welding, leading to sensitization.Utilize low-heat input welding techniques and minimize interpass temperatures to preserve the material's corrosion resistance.

Common Applications

  • Chemical Processing Pipelines
  • Food and Beverage Processing Equipment
  • Pharmaceutical Manufacturing Systems

⚠️ Engineering Warnings

  • Avoid prolonged exposure to chlorides and high temperatures above 800°F (427°C) which can compromise corrosion resistance.
  • Ensure proper post-weld heat treatment or cleaning procedures are followed to prevent stress corrosion cracking and maintain optimal performance.
