Product Introduction

Wear and abrasion resistant steel is a type of steel that is designed to withstand wear, abrasion, and impacts from heavy machinery or other objects. It is commonly used in industrial and mining applications where equipment is subjected to intense wear and tear.

The most common types of wear and abrasion resistant steel are NM360, NM400, NM450, NM500, NM550. These different grades of steel have varying levels of hardness and toughness, making them suitable for different applications.

- NM360: This steel grade has a hardness of 360HBW, which makes it suitable for medium-wear applications such as excavator buckets, bulldozers, and dump trucks.

- NM400: This steel grade has a hardness of 400HBW, which makes it suitable for high-wear applications such as mining and quarrying equipment, conveyor belts, and crusher liners.

- NM450: This steel grade has a hardness of 450HBW, which makes it suitable for extreme-wear applications such as drilling rigs, crusher hammers, and blades for shredders.

- NM500: This steel grade has a hardness of 500HBW, which makes it suitable for severe-wear applications such as earthmoving equipment, cement plants, and sandblasting machines.

- NM550: This steel grade has a hardness of 550HBW, which makes it suitable for extreme-wear applications such as abrasive blasting equipment, heavy-duty transportation, and mining equipment.

Overall, wear and abrasion resistant steel is a crucial material for industries that rely on heavy machinery and equipment. With its high durability and strength, it allows companies to improve their operations and reduce costly repairs and downtime.
