Sledgehammer Steel, AR Plates & Manganese Steel
Sledge Steel stocks 6 grades of specialty impact and abrasion wear steels in various sizes and thicknesses, allowing us to provide the best material to suit your needs.
Wear Plates
Dynamic AR 500 Plates
Dynamic AR 500 heat treated wear steel plate is intended for severe wear applications requiring a high degree of abrasion resistance.
​
Originally developed for extreme wear applications including ballistics, Dynamic AR 500 plates combines a high carbon level with Sledge's proven manganese chrome/nickel chemistry to produce a steel with up to ten times the wear resistance of ordinary steel.
​
Dynamic AR 500 is heat treated to provide a BHN range of 477 to 534 with a typical BHN of 514.
Abrasion resistance is typically 5:1 compared to mild steels.
Dynamic AR 600 Plates
Dynamic AR 600 heat treated wear steel plate is intended for severe sliding wear applications requiring a high degree of abrasion resistance.
​
Developed for ballistic protection, Dynamic AR 600 plates combines a high carbon level with Sledge’s proven manganese chrome/nickel chemistry to produce a steel with up to fifteen times the wear resistance of ordinary steel.
​
Dynamic AR 600 is heat treated to provide a BHN range of 570 to 640 with a typical BHN of 627.
Sledgehammer Dual
For projects that require particularly high sliding abrasion resistance, SLEDGEHAMMER Dual can provide the same performance as Carbide Overlay, at roughly 1/2 the price.
​
SLEDGEHAMMER Dual is an alloy comprised of SLEDGEHAMMER Steel, already known for its durability and impact abrasion resistance, alloyed with “High Titanium Carbides” (0.6%). This unique grade is mainly dedicated to sliding abrasion where conventional water quenched steels (500HB, 550HB), hardfacing plates or hard-cast parts are traditionally used.
​
Similar to SLEDGEHAMMER, SLEDGEHAMMER Dual also has unique “Work Hardening” properties. With impact, SLEDGEHAMMER Dual will “work harden” from 480 BHN to 560 BHN.
Manganese Steel
Manganese steel is an austenitic steel, which means it is non-magnetic. This property makes it useful in many applications such as bottom plates for lifting magnets, separator drum shells for magnetic materials, wear shoes on electric brakes, and more.
​
Manganese steel has Work Hardening properties, which means that it becomes harder and harder the more it is impacted or compressed.
​
The “Hadfield” grade has an original hardness of approximately 220 BHN (Brinell Hardness Number). With continued impact and /or compression, it will surface-harden to over 550 BHN.
​
It should be noted that only the outer skin surface-hardens with wear, while the sub-surface remains highly ductile and tough. As the surface wears, it continually renews itself, becoming harder and harder.
Dynamic Armor Kits & Plates
​Applies to NIJ, CEN (BR)1063, UL752, MIL 46100, 12560
The AR 500/600, Mil 46100, 12560 steel plates are ballistically certified for maximum protection. They are blasted and painted to customer specifications. They are nested on large plates with CAD assisted design. In order to reduce the “heat affected zone” (HAZ), High-Definition Underwater Plasma, or Water Jet cutting is used.
​​
Armor kits for vehicles are cut-to-size, skidded and shipped in days. Armor kits can be applied to all makes & models (military & commercial). It can be customized for special purpose vehicles. Cash in transit.

Sledgehammer Steel
SLEDGEHAMMER Steel is renowned for being very tough, very hard, very abrasion-resistant, and very easy to machine, while still maintaining a competitive price.
SLEDGEHAMMER Steel offers the following advantages:
1. Best Wear Resistance of any abrasion resistant plate
-
8 times greater wear than mild steel
-
2-4 times greater life than conventional 500 BHN steels
2. Reduce plate thickness up to 25% vs AR 500 (e.g. a 1.5″ plate of SLEDGEHAMMER Steel could be used in place of a 2″ plate of AR 500 steel)
3. Ability to “Work Harden” from 470 BHN to 560 BHN
4. Ease of processing compared to conventional 500 BHN steels
5. Can be Welded with Low Hydrogen Rod providing a major cost saving
6. No pre or post heating required for welding
