About APAC Stainless 02

APAC Stainless 02 is a high-purity argon blend with 2% oxygen formulated for MIG welding austenitic and duplex stainless steels. The small oxygen addition stabilises the arc and improves weld-pool wetting for a smooth, well-shaped bead, while remaining low enough to avoid excessive oxidation so the alloy's corrosion resistance is preserved. It is ideal for 304 and 316 stainless, nickel alloys and food-grade or pharmaceutical fabrication.

APAC Stainless 02 is supplied in E-size and G-size cylinders, charged to 19,000 kPa with an AS 2473 Type 10 outlet, and delivered across Melbourne. Compare the full welding range →

⚠ Main Hazards

  • Simple asphyxiant — the argon-rich mixture is heavier than air and can pool in pits, trenches and low or confined spaces, displacing breathable oxygen with no warning.
  • No warning properties — colourless, odourless and tasteless. The gas cannot be detected by human senses at dangerous concentrations.
  • High-pressure stored energy — cylinders are charged to 19,000 kPa. Secure cylinders upright, fit the valve cap for transport and inspect the valve before use.
  • Rapid release of gas can cause cold burns to skin or eyes on contact with escaping gas, valves or regulators.
