Description:

The ultimate maintenance and repair steel electrode for welding steels with the highest strength and maximum ductility (AC/DC). This electrode type i s considered the maintenance and repair standby in every industry throughout the world.

Typical Application:

Assures noncracking welds on problem steels such as high carbon, tool, stainless, spring, manganese and dissimilar steels. MS3000 is particularly advantageous when the alloy content of the steel to be welded is unknown. This unique electrode is so versatile that its applications are too numerous to specify.

Features:

• Tensile strength Up to 120,000 psi
• Yield strength Up to 85,000 psi
• Ductility Up to 35% elongation in 2
• Reduction of area 30%
• Charpy V notch 75 ft/lb. @ room temperature
• Rockwell B hardness 93 102 HRB
• Brinell hardness 200 300 HB
• Frictional resistance Excellent
• Abrasive resistance Mild
• Will not respond to heat treatment
• All position, except vertical down
• 3/32" electrode is 9" long
• 1/8" electrode is 14" long

Procedure:

• Use either AC or DC reverse polarity
• Clean weld area
• Bevel heavy sections
• For high carbon steels, a preheat of 400°F is recommended
• Hold a short arc
• Run stringer beads
• Peening will help relieve stresses
• Let each pass cool and slag will peel off easily
