Product Description

GB：E330MoMnWNb-15
AWS：
Current：Used for welding the same types of stainless steel materials working under high temperatures of 850-900 °C, and manifolds and bulged pipes ( such as of Cr20Ni32 and Cr18Ni37 materials) in the reformers.
Main Applications：

A607

According with GB E330MoMnWNb-15

Introduction: A607 is a kind of pure austenitic Cr16Ni35 stainless steel electrode with basic coating. Due to the strengthen elements added to the electrode, it has excellent high temperature performance. DCRP (Direct Current Reversed Polarity). All-position welding.

Uses: Used for welding the same types of stainless steel materials working under high temperatures of 850-900℃, and manifolds and bulged pipes ( such as of Cr20Ni32 and Cr18Ni37 materials) in the reformers.
