Description

Weld Star – A30 (ER 70S-A1) TIG Wire (2.4mm) 5kg

Weld Star – A30 TIG Wire is a copper-coated, heat-resisting wire designed with 0.5% molybdenum. Specifically formulated for welding low alloy creep-resistant steels, this wire ensures high tensile strength and resistance to cold cracking.

Features and Benefits:

  • Heat Resistant: Suitable for applications with recommended working temperatures of up to 500°C.
  • High-Quality Welds: Designed for welding low alloy creep-resistant steels requiring high tensile strength.
  • Cold Crack Resistance: The weld deposit is highly resistant to cold cracking, ensuring durability.
  • Versatile Applications: Ideal for use on creep steels in various sectors including steam boilers, pressure tanks, gas pipes, shipbuilding, petrochemicals, heat exchangers, cranes, bridges, and more.
  • Quality Production: Manufactured using virgin raw materials from specialized steel mills, guaranteeing consistent quality and reliability.

Common Applications:

  • Steam Boilers & Pressure Tanks: Ideal for the construction of steam boilers and pressure tanks.
  • Petrochemical Industry: Used in the petrochemical sector for various applications.
  • Shipbuilding: Suitable for shipbuilding applications.
  • Infrastructure: Used in the construction of cranes, bridges, and other infrastructure projects.
