Jual Plat Quard 450

Description
Quard 450 offers high wear resistance in applications exposed to increased wear from sliding abrasion and heavy impacts from crushing rocks, gravel, sand or other harsh abrasives.

With a typical hardness of 450 Brinell, Quard 450 combines high strength with very good workability, especially in welding and cold forming.

Quard 450 combines the attributes of hardness and toughness with improved crack resistance and high durability.

Quard 450 in thinner gauges, opens up new design solutions for applications aimed at reducing weight, increasing payload and durability as well as reducing energy consumption and the impact on the environment.
