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:
| Platinum SD-980 | Platinum CX-1800 | |
| Type | Solid | Flux-cored |
| Gas Required | Yes | No |
| Abrasion Resistance | Moderate | Very High |
| Impact Resistance | High | Low/Moderate |
| Position | All-positional | Horizontal / down hand only |
| Cr Content | 9.5% | 23% + special carbides |
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*.

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.
