Hyster White Iron Wear Blocks combine a number of metallurgical properties into one unique wear resistant material which today has been widely used in most abrasive wear applications. Hyster White Iron Wear Blocks is an extremely hard, laminated bi-metallic, wear resistant composite, which has a nominal hardness of 700 BHN (HRC 63) minimum. It is produced by combining a highly alloyed chromium-molybdenum white iron and metallurgically bonding it to a mild steel backing plate. The bonding possesses high shear strength of over 200 Mpa and will not separate.

The alloy’s microstructure is made up of primary and secondary chromium carbides which are supported by a hard, finely dispersed Martenstic matrix. The hardness of alloy provides maximum abrasion resistance, while the steel backing plate acts as a means of absorbing high impacts and allows easy fitting and use.

Typical applications of Hyster White Iron Wear Blocks include Excavator Buckets, Loader Buckets, Dragline Buckets, Face Shovel Buckets, Spider Arm Guards on Crushers, Discharge Chutes, Rock Boxes, Grizzly Bars on Feeders, Shredder and Grinding Mills, Sugar Cane Knife Edges, Adaptor/Attachment Protection, Dredging Equipment, Screen Feed Distribution and Fee Hopper Wear Areas.

Hyster White Iron Wear Blocks have been examined and tested for grade, quality,chemical analysis and hardness which guarantee high abrasion and impact resistance.

63HRC Chocky Bars

63HRC Chocky Bars are chocky wear bars were first in the market about 15 years ago and had been well proved in US and Australia market.

63HRC Chocky Bars are easy to use. There is no pre-heating or post heating required when wielding into place. They are easy to form and weld onto inner and outer contoured surfaces. The versatility of 63HRC Chocky Bars allows unique layouts to be created on equipment to reduce the effects of abrasion. The backing plate can be supplied with grooves to aid in the forming, bending and cutting of the block.

The unique, formable design of 63HRC Chocky Bars offers effective protection on sliding abrasion in high wear areas for a wide range of applications on fixed and mobile plant equipment including:

● Wear bars for Buckets

● Chute Liners

● Crusher Liners

● Road planners

● Rock box ledges

● Hammer Tips
