NSS-430

Specification

Description

• NSS-430 is a lime titania type of electrode for all-position welding
• Features excellent corrosion resistability
• Good oxidation resistability to nitric acid

Application

• For welding 17% Cr stainless steel, such as SUS430

Remarks

Keep the arc length as short as possible

Weaving width should be within 2.5x electrode diameter

Welding current should be as low as possible

Dry electrode at 300-350º C for 30-60 minutes before use

Pre-heat interpass temperature at 150-250º C

Post-weld heat treatment at 700-820ºC
