Weld Star - ER 347Si Stainless Wire (1.2mm) 15kg

Each
Availability: In stock
Order Code: 6011100437

Features and Applications

Austenitic stainless steel wire with a significant presence of niobium, that provides resistance to intergranular chromium carbide precipitation, thus increasing the resistance to intergranular corrosion.

Increased silicon content promotes weld pool fluidity to give a smooth deposit appearance.

Ideal for welding and overlay of chromium-nickel stainless steel base metals of similar composition, stabilised either by Nb or Ti (e.g. types 321 and 347).

Precision layer wound for superior wire feeding characteristics.

Typically used on applications for the chemical industry, particularly at high temperatures (e.g. equipment intermittently heated within a temperature range varying from 400°C to 800°C). Including applications such as firewalls, pressure vessels, food processing, dairy, oil and textile industries etc.
