Astro 375 Super Electrode

Welding Highest Alloy, Carbon and Stainless Steels

Description

Super Electrode for Welding Highest Alloy, Carbon and Stainless Steels

Astro 375 is a high tensile welding electrode, capable of welding dissimilar steels in all positions.

 

GENERAL CHARACTERISTICS:

Astro 375 electrodes are low temperature electrodes, designed for contact work, thus keeping the base metal at the lowest possible temperature during welding. This helps eliminate warpage and distortion of the base metal. There is a smooth arc transfer of the weld metal and the deposit is not heat treatable, yet fully machinable.

 

TYPICAL APPLICATIONS:

The principal of this electrode is to eliminate the guess work that very often goes into welding steels of unknown analysis. The welder, who is an expert in his trade, cannot be expected to know the chemical analysis or tensile strength of a steel that, in some cases, may be many years old. Downtime is a factor no industry wants, nor can it accurately cost.  A diligent use of this electrode in the maintenance repair area will reduce downtime.

 

FEATURES:

  • Work hardens – the longer you use it the tougher it becomes
  • Magnetic deposit (cannot be heat treated)
  • Has the ability to resist cracking
  • Extremely high yield strength
  • Ultra high tensile strength
  • Excellent heat resistance
  • High elongation

 

ASTRO 375 May be used to weld:

  • Very high alloy steels
  • Stainless steels
  • Aircraft steels
  • Spring steels
  • Tool steels
  • Air hardenable steels
  • Nickel Clad steels
  • Pressure vessels
  • Dissimilar steels
  • Dies

 

QUALITIES:

Astro 375 has these remarkable properties:

Tensile strength: Up to 120,000 P.S.I. (830 MPa)

(after work hardening) Up to 180,000 P.S.I. (1240 MPa)

Yield strength: Up to 90,000 P.S.I. (620 MPa)

Elongation: 22 to 25%

Hardness: 200 Brinell

 

WELDING PROCEDURES:

Clean weld area of all foreign material. Preheating to 150-250C will help minimise cracking on high alloy steels, tool steels and stainless steels. Strike an arc and hold a short arc or touch the electrode to the base metal. Use stringer beads, do not weave and let each bead cool before removing slag. Slag is easily removed after each pass with light chipping and brushing.
