Weld Star – A33|ER 90S-B3 TIG Wire (3.2mm) 5kg
£52.50
Product Description
Features and Applications
Low alloy copper coated wire with 2.25% Cr and 1% Mo content used for the welding of heat-resistant steels.
Produces quality welds on pressure piping or boiler work.
Designed to sustain elevated temperatures within demanding work environments.
Recommended working temperatures of up to 600°C.
Typical applications include pressure piping in steam power generating plants, boiler and heat exchanger tubes, chemical and petrochemical processing equipment etc.
Green wire is produced using virgin raw materials sourced from specialised steel mills, which ensures consistent reliability and quality.
