Description

Weld Star – A30 (ER 70S-A1) Wire (0.8mm) 15kg

Weld Star – A30 (ER 70S-A1) Wire with a diameter of 0.8mm is a copper-coated, heat-resisting wire that contains 0.5% molybdenum. This wire is specifically designed for welding low alloy creep-resistant steels, ensuring a high tensile strength. The weld deposit it produces is known for its resistance to cold cracking. It’s recommended for environments with temperatures up to 500 degrees Celsius. Precision layer-wound, this wire ensures consistent and uninterrupted feeding. It’s particularly favored in industries like shipbuilding, petrochemicals, and construction, especially for steam boilers, pressure tanks, gas pipes, and more. The green wire is produced using virgin raw materials from specialized steel mills, guaranteeing consistent quality and reliability.

Key Features:

  • Copper-coated wire infused with 0.5% molybdenum for enhanced strength.
  • Designed to resist cold cracking, ideal for welding low alloy creep-resistant steels.
  • Precision layer-wound for consistent and uninterrupted feeding.
  • Suitable for high-temperature environments up to 500 degrees Celsius.
  • Produced using virgin raw materials for consistent reliability.

Common Applications:

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

  • Construction of steam boilers, pressure tanks, and gas pipes.
  • Shipbuilding sector infrastructure.
  • Petrochemical industry applications.
  • Crafting heat exchangers, cranes, bridges, and more.
  • Welding of specific base materials like P295GH, P355GH, 16Mo3, and many others.
