Instructions - HTS528

The strongest brazing rod made for joining cast iron and steel, HTS-528 is thin flowing for close-fit joining and repairs on all cast iron, steel, copper, bronze, nickel, and brass. It will effectively join dissimilar metals.  Master Welders rate its wetness on ferrous and non-ferrous metals as excellent, and while it is very hard, it is still fully machinable.
The perfect rod to use for high-heat applications up to 760�C , such as a cast iron manifold, or for high-stress areas, including joining cast iron ears or repairing cracks in blocks, or for body work like replacing sheet metal on your rusty floor of your car.

Instructions for the 528-Brazing Rods

 

Melting the base metal is not necessary since the 528 rod has a built-in flux. Consequently, clearance should be around .003 for maximum tensile and shear strength. The 528 rod takes extreme heat, above 760�C to penetrate the pores of the metal so you will need oxygen and gas to produce this heat. HTS-528 can be used to braze cast iron, brass, nickel, copper, and more than 50 different kinds of steel, including stainless. Open the pours around the area to be repaired, drill, and grind out a U shape in the metal, so it is no longer a hairline crack.

 

We recommend first practicing with cast iron by grinding a slot 1 - 3mm wide into the metal. Use a brazing tip to bring the metal to 760�C . The metal will start to turn red at 315�C, but continue heating, test the rod on the metal 5-6 mm outside the bulk of the flame. The rod has a flux core that will melt much lower than the rod, so if the rod itself will not melt, have patience. When you are close to 760�C, it will look like you're going to burn a hole in the metal but do not worry. Once you see the rod itself is melting, scratch the rod all around the area to be repaired. The rod will melt and, with the help of the flux core, will fuse down into the metal.

 

When you pull the torch away, it will be cherry red for about 20 seconds. If you have followed the instructions explicitly and scratched the rod all around the area to be repaired thoroughly allowing the flux to mix with the melted rod you will have the strongest weld possible on that particular metal. You may then grind, shape, polish, and paint as desired.

 

REMEMBER: WELDING/BRAZING CAN BE DANGEROUS

ALWAYS USE THE APPROPRIATE SAFETY EQUIPMENT INCLUDING EYE PROTECTION
