Wear-Resistant Steel NM400HiT – NM500HiT
General Technical Characteristics
Wear-resistant steel grades NM400HiT and NM500HiT are specialized plate steels that combine high hardness with enhanced heat resistance (HiT — High Temperature). These steels are designed for operation in environments where both elevated temperatures and severe abrasive wear are present.
Brinell hardness values:
- NM400HiT — ~400 HB
- NM500HiT — ~500 HB
The key advantage is the ability to retain mechanical properties and wear resistance at elevated temperatures, where standard wear plates may lose performance.
Supplied in plate form with thicknesses ranging from 4 mm up to 80 mm and more.
Chemical Composition and Mechanical Properties
NM-HiT steels feature an alloyed composition with elements that improve heat resistance, including carbon (C), manganese (Mn), silicon (Si), chromium (Cr), nickel (Ni), molybdenum (Mo), and others.
This composition ensures:
- resistance to thermal degradation
- retention of hardness at elevated temperatures
- oxidation resistance
Mechanical properties:
- hardness: 400–500 HB
- yield strength: from 900–1200 MPa
- high wear resistance at elevated temperatures
- structural stability under thermal loads
Applications
NM400HiT – NM500HiT steels are used in industries where both heat and wear are critical factors:
- cement industry (kilns, cyclones)
- metallurgy
- power generation
- equipment handling hot materials
- slag and clinker transport systems
They are ideal for components exposed to both heat and friction.
Features
The main feature of NM-HiT steels is the retention of performance at high temperatures. This allows you to:
- extend equipment service life
- reduce deformation and thermal damage
- lower maintenance frequency
- improve operational reliability
The material can be processed using standard methods, with consideration for temperature-related requirements.
Standards and Supply Formats
