The maximum thickness available for NM450 wear plates varies considerably by supplier and production route. From a commercial availability standpoint, NM450 plates are commonly offered in thicknesses ranging from as thin as 1.2 mm up to 200 mm. Some suppliers list stock thicknesses from 4 to 100 mm, while others advertise broader ranges extending to 500 mm for the wider NM-series family.
This variation reflects differences in manufacturing capability and intended application. Thin NM450 plate is typically used for chute liners and hopper surfaces where weight matters, while thicker sections are employed in crusher components and heavy-duty wear parts requiring structural rigidity. Thickness tolerances also matter: for plates in the 4–10 mm range, typical tolerance is ±0.4 mm under EN 10029 Class A; for 30–80 mm plate, tolerance widens to ±0.8–1.0 mm.
It is important to distinguish between nominal availability and practical supply. While some mills can produce NM450 up to 200 mm or beyond, the most commonly stocked and competitively priced range is 4–80 mm. Buyers specifying NM450 should confirm thickness capability with the mill and verify that hardness and toughness properties are guaranteed at the required section size, as through-thickness properties can vary with plate gauge.
