Introducing PLATINUM SD-980 Solid Hardfacing MIG Wire

A Versatile, High-Performance and Easy-to-use Hardfacing Welding Wire

Versatile and Easy-To-Use

Being a solid hardfacing wire (rather than flux-cored), Platinum SD-980 requires minimal (if any) additional set-up.  If you already weld with solid wire, the chances are you won't need to change drive rollers etc.

SD-980 is available in 1.2mm.  With a minimum requirement of around 120 Amps, SD-980 will usually run well off MIG welders with output of 200 Amps or above.  Use with normal Ar-Co2 MIG gas.

While some hardfacing wires can be "tricky" to run, or require a careful procedure to be followed (to prevent issues such as weld deposit chipping / breakage) - Platinum SD-980 is typically very hassle-free, normally requiring no special procedures such as buffer layers, pre-heating, etc.

Available in 4.5kg (and 15kg) Spools

Got a small job to do?  Welding machine only takes smaller 200mm spools? No problem - SD-980 comes in 200mm/4.5kg spools.... as well as 300mm/15kg spools.

All-Positional Hardfacing Wire

While many hardfacing wires are often suitable only for use in horizontal (or down-hand) position, SD-980 is all-positional... making it a great choice for those out-of-position hardfacing tasks. 

Let's say you need to hardface an auger/screw for example; positioning the job so that every weld is in a horizonal / downhand position may be very difficult.  In such applications, SD-980 works well and can be applied vertical-up, vertical-down or even overhead if needed.

Abrasion Resistance with High Impact Strength

Platinum SD-980 is a great "all-rounder", combining abrasion resistance with moderate-to-high impact strength. This makes it a great choice for metal-to-ground (or ground-engaging) applications where frequent &/or heavy shock and blows are likely to occur.

SD-980 is also suitable for metal-to-metal applications such as shear & guillotine blades, punch dies, tracks, pulleys, etc.

Typical Applications:

• Excavator bucket lips and teeth
• Points and tynes
• Screws & Augurs
• Pulleys (eg: drag-line pulleys)
• Dump-truck / tipper trays / bodies
• Shear blades
• Tracks
• Crushing wheels and jaws
• Guillotine blades, punch dies

Comparisons

SD-980 Vs CX-1800 Gasless Wire:

Other Products Comparible with Platinum SD-980*:

Approx. chromium (cr) content shown. A higher Cr content will typically give a longer wear life against abrasion.

• Stoody 965-G  (Cr ~6%)
• Lincore 55-G/O  (Cr ~5%)
• Robodur K 600-G  (Cr ~6%)
• Welding Alloys L-G/O  (Cr ~8%)
• INE Inefil 600-BR  (Cr ~9%)

Platinum SD-980 = Cr 9.5%

Micro-Cracking (yep it's normal)

SD-980 weld deposit will typically "relief-check".  Also known as "cross-checking", this means that the weld will form fine "micro cracks" after welding, due to the hardness of the weld deposit.

This is not a defect - in fact it is normal for many (if not most) hardfacing wires.

Micro-cracking will not affect the performance of the hardfacing deposit*.

*Other than in some unique/special applications, see below for further information

Limitations

While SD-980 is certainly a very versatile wire - there's no such thing as a "one size fits all" hardfacing solution.  We believe in being up-front about our products, so here's some applications where SD-980 is not recommended or may not be the best choice;

Not recommended for equipment that will be submerged in sea water (eg sand dredging equipment). 
Becuase SD-980 exhibits micro-cracking (see above), sea water can corrode under the hardfacing layer and cause it to fall off. 

Not recommended for extreme Impact.
While SD-980 will handle 'moderate' impact very well - if the job involves constant, heavy impact with very little abrasion (eg repetitive hammer blow impact), SD-980 may not be the best product to choose.

Very high abrasion with low impact.
SD-980 will handle abrasion at all levels. However for applications where wear is mostly caused by abrasion with low impact, we recommend Platinum CX-1800 wire which not only has a higher Cr content (23%), but also includes special carbides that help it out-perform other hardfacing wires many times over... and will offer much longer wear life and equipment service life.

Field Applications / Windy Environments:
For applications where the wire is to be used in the field, it may be more convenient to use a gasless hardfacing wire such as CX-1800.
