Description

Weld Star- A30 (ER 70S-A1) Wire (1.2mm) 15kg

Weld Star- A30 (ER 70S-A1) Wire is a copper-coated wire infused with 0.5% molybdenum. It’s specifically designed for welding low alloy creep-resistant steels. This wire offers a high tensile strength and is highly resistant to cold cracking, making it ideal for applications that require durability and strength. It’s precision layer-wound, ensuring consistent and uninterrupted feeding. The wire is particularly suitable for environments with temperatures up to 500 degrees Celsius and is a staple in industries like shipbuilding, petrochemicals, and construction.

Key Features:

  • Copper-coated wire containing 0.5% molybdenum for enhanced strength.
  • Designed for welding low alloy creep-resistant steels.
  • Highly resistant to cold cracking.
  • Precision layer-wound for superior wire feeding characteristics.
  • Suitable for high-temperature environments up to 500 degrees Celsius.

Common Applications:

The Weld Star- A30 (ER 70S-A1) Wire is versatile and is commonly used for:

  • Construction of steam boilers and pressure tanks.
  • Crafting gas pipes for the shipbuilding sector.
  • Petrochemical industry infrastructure.
  • Building heat exchangers, cranes, and bridges.
  • Other applications requiring high tensile strength and resistance to cold cracking.
