SLEDGEHAMMER Steel, AR Plates, Manganese Steel
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
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.
