Hardface Technologies, a Cleveland-based business unit of Postle Industries, has introduced a product that it says will be “the ultimate hardfacing wire for tire shredding knives.”

The company says its Postalloy Ultra-Shred 580 is a metal-cored, gas-shielded wire with numerous tightly packed carbides for excellent abrasion resistance under high impact. One layer deposits exhibit wear characteristics that would be expected from a chromium carbide hardfacing product, Hardface Technologies adds. 

Hardface says the knife’s alloy properties create a resistant cutting edge, even under the high heat conditions created by extreme friction. Deposits are slag free and exhibit a hardness of 55-58 Rc on the Rockwell scale of hardness.

“Postalloy Ultra-Shred 580 has proven to be an exceptional way to hardface tire shredding knives," says Russ Speese, Hardface Technologies vice president of sales and marketing. “Beyond that application the product has also seen great success in other areas, including cutting tools, shear blades and hot or cold trim dies.”

Hardface Technologies manufactures a range of what it calls wear-resistant solutions for applications in a variety of industries. The company’s hardfacing products, which it says have been engineered specifically for high wear environments, are available through the company’s worldwide distribution network.
