Weld Star – CrMo5|ER 80S-B6 TIG Wire (1.6mm) 5kg


SKU: 3010300404 Category: Tag: Brand:

Product Description

Features and Applications

Low alloy copper coated wire with 5% Cr and 0.5% Mo content used for the welding of heat-resistant steels.

High strength and corrosion resistant particularly in environments involving hot hydrogen gas.

Recommended working temperatures of up to 650°C.

Typical applications include pressure piping in steam power generating plants, boiler and heat exchanger tubes, oil refineries, chemical and petrochemical industries.

Green wire is produced using virgin raw materials sourced from specialised steel mills, which ensures consistent reliability and quality.
