NM550 Wear Resistant Steel

NM550 Wear Resistant Steel

Introduction to NM550

NM550 is a wear-resistant plate, NM means wear-resistant, 550 is a hardness value. Usually see NM550A/B, representing the value A means no

Impact. The value B means impact at room temperature of 20°. Like the other container plate types there are shocks D for minus 20 degrees, "E" for shock

Minus 40 degrees impact. F indicates the impact value of -60°. The NM550 has a Brinell hardness of 550(HBW).

NM550 delivery status: tempering (quenching + tempering)
