Select 90C-B3 is alloyed with approximately 2 1/4% chromium and 1% molybdenum. This composite metal cored electrode, intended for single and multiple pass welding, produces a high strength weld deposit which is generally post weld treated. Care must be taken with welds which are used in the as-welded condition. Classification of this electrode is, therefore, in the postweld heat-treated condition.
Features
Greater tolerance for mill scale than solid wires.
Enhanced welder appeal.
Higher productivity due to faster travel speeds.
Applications
Select 90C-B3 is designed for welding the 21/4 Cr-1 Mo steels used in high temperature and pressure piping as well as pressure vessels
ASTM A387 - Grade 22 is a standard grade of steel used in many of these applications
Select 90C-B3 may also be used to weld Cr-Mo steels to carbon steel
