Description
High-performance hard-facing welding rod, ideal for ground-engaging equipment. Platinum 943 deposits extremely hard, abrasion resistant CrNb carbides, offering long wear life with both exceptional abrasion resistance and impact strength. Ideal for hard surfacing applications where resistance to high or extreme abrasion (in particular sliding abrasion) and moderate to heavy impact are required.
Due to the nodular shape of the complex carbides, Platinum 943 deposits are capable of withstanding heavier impact levels than standard chromium-carbide electrodes. Typical applications include; buckets, lips, screws, hammers, teeth, crushing equipment, etc. Typical hardness 60-65 HRC (1st layer). Supplied in a 1kg re-usable convenience pack to keep electrodes in good condition.

Items came swiftly and communication was perfect. All is well.
Looks great and well made. Will do the job it was bought for.
Good discounted price, that's what I waited for.
The team at Beyond Tools are legends at their customer service, fast response and they go the extra mile
10/10
Brilliant
The range on offer is complete, the prices are god, and the items were well packed and delivered promptly. All good.
Abbot & Ashby every time if you want quality that works and lasts.
Exactly what I was looking for. A company in the states use an almost identical knife under a different brand name, minor differences, nothing impactful. This has been the knife I have used for work for 10+ years. I keep 2 on hand in case something happens to my daily use one. I will gladly pay the exchange and shipping cost to keep using what works so well for me.
Excellent product Excellent price just needed to wait a little longer for them to arrive, but that's no problem really.
The ordering and delivery process was very straightforward, very happy with the products I ordered. Great service from Beyond Tools, I will use them again.
I have been chasing additional bobbins for years. The original seller did not offer additional spindles.
Beyond tools is able to supply additional spindles. Great
We purchased from beyond tools as we were struggling to locate some brass items in the UK and Europe, we got a great prompt service.
Great service and range of products
The mini hinges are good quality and the service was prompt considering we are in the United Kingdom.
