Chromium Carbide Overlay Plate
Austenitic alloys with up to about 0.7 % carbon and 20-30 % alloy (usually about equal parts of manganese and chrome with some nickel) provide stable austenite; even on carbon in high dilution situations, and low alloy steels. This makes them a much better choice than the austenitic manganese alloys for overlay on carbon and low alloy steels.
Well-designed austenitic surfacing alloys are extremely tough, ductile and work-hardenable. They offer excellent impact resistance but very low abrasion resistance (with little improvement as work-hardens) and have no relief checks.
These alloys will normally work-harden to a nominal surface hardness up to 50Rc and although this improves their abrasion resistance they still retain their good impact resistance. The austenitic surfacing deposits like the austenitic manganese base metals (see Base Materials) should not be exposed for extended periods to temperatures over 500°F (260 °C). This is to minimize embrittle.
HP Wear Plate is a kind of Compound Steel Plate consisting of a low carbon or alloyed steel base plate and a layer of wear resistant deposit.
The low carbon steel base plate makes Clad Plate to be welded, bolted or studded to existing structures, while the hard facing provides the premier wear-resistant surface capable of working in all applicable service conditions at either ambient or elevated temperatures.
Due to its excellent properties, HP CCO Plate works for long-lasting service life and superb performance, which are well applied to the industries like Cement Plant, Steel Mill, Mining Site, Power Generation, Construction where needs combat with abrasion.

How to Join Metals Without Welding? Specifically, how can you join iron, steel, and other metals together without using welding? There are numerous situations where it’s perfectly normal and even advantageous to look for alternatives to welding. Think about the world of do-it-yourself projects, where you don’t have access to a welder. Or consider scenarios where there aren’t enough skills to perform a welding job effectively, satisfactorily, or safely. But it doesn’t stop there—industrially speaking, it’s often much more convenient to replace welding by finding an efficient method to join metals without actually welding them. Welding isn’t always the most effective or cost-efficient solution, not to mention that the aesthetic results from welding may not be particularly pleasing. Additionally, welders are frequently exposed to health risks, such as exposure to infrared radiation and respiratory damage from emissions like carbon monoxide, phosgene, and ammonia. In short, there are plenty of excellent reasons to find the best method for joining metals without welding. Let's explore these options!
Alternative to Welding: Brazing
One method to join metals without welding is brazing. It’s a widely used industrial alternative to welding, with some similarities to it. We’re talking about bonding two metal surfaces by heating a filler metal, which melts and flows between the adjacent metals, creating a stable joint as it cools. There are various methods for brazing, including using a furnace, torch, or under vacuum. However, it’s worth noting that the costs of brazing can be equal to or even higher than those of welding, and the mechanical strength tends to be lower. Moreover, it’s certainly not a technique suitable for someone who occasionally needs to join pieces of metal.
Joining Metals Without Welding: Riveting
Another common alternative to welding is riveting, especially when it comes to joining sheets or any metals with reduced thickness. Riveting can also be used in non-industrial settings like DIY projects since the riveting tool—a riveter—is simple and relatively affordable. The concept is straightforward: the metals to be joined are first drilled, then connected using rivets, which are cylindrical pins bent to "weld" the two pieces together. The downside of riveting lies in its limited shear resistance due to the small overlapping areas involved. Aesthetic drawbacks should also be considered, along with the necessity of drilling through the metals.
Securing Metals Without Welding: Lockbolts
The discussion about riveting applies equally well to lockbolts. Actually, here you don’t even need a riveter—you just need a drill for making the necessary holes and a wrench to secure the lockbolt itself. The only challenge is ensuring precise hole placement. Similar to riveting, lockbolts suffer from reduced strength (due to the limited area involved), the need for drilling, and aesthetic concerns.
Joining Metals Without Welding: Structural Adhesives and Biadhesives
Finally, we have the "newcomers," namely structural adhesives and high-performance biadhesives. In truth, metal adhesives have been employed for decades, especially at an industrial level. Structural adhesives and biadhesives are excellent alternatives to welding because they offer greater design flexibility, resulting in a cleaner final product. It’s worth mentioning that using structural adhesives and biadhesives eliminates the need for drilling, adds no weight to the metals, and involves no vibrations, noise, or visual disturbances. These benefits come with high mechanical strength, as structural adhesives and high-performance biadhesives bond over a much larger area compared to rivets, spot welds, or bolts. Furthermore, using structural tapes and adhesives requires no additional machinery, and our online store offers perfect solutions for every situation—whether in small or large formats, as tapes or liquids, for different metals and applications.
In conclusion, while welding remains a staple in many industries, exploring alternatives like brazing, riveting, lockbolts, and adhesives opens up new possibilities for joining metals efficiently and safely, all while enhancing aesthetics and reducing risks. Whether you're working on a DIY project or managing industrial processes, these methods provide valuable options tailored to your specific needs!
