Sheet Steel LG600QT
General Technical Characteristics
Sheet steel LG600QT is a high-strength, wear-resistant steel that has been quenched and tempered (QT — Quenched & Tempered). This grade is designed for operation under severe abrasive wear and high mechanical loads.
The key characteristic is its high hardness of approximately 600 HB, providing excellent wear resistance and long service life in harsh environments.
It is supplied in plate form with thicknesses ranging from 6 mm up to 100 mm and more.
Chemical Composition and Mechanical Properties
LG600QT steel features an alloyed chemical composition including carbon (C), manganese (Mn), silicon (Si), and alloying elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), boron (B), and others.
Heat treatment (quenching and tempering) ensures:
- uniform hardness throughout the thickness
- high strength
- improved impact toughness compared to conventional hardened steels
Mechanical properties:
- hardness: ~550–620 HB
- yield strength: from 1200 MPa and above
- excellent resistance to abrasive wear
- good resistance to impact loads
Applications
LG600QT is widely used in industries with extremely demanding conditions:
- mining industry
- quarry and excavation equipment
- buckets, blades, and liners
- crushing equipment
- bulk material handling
This steel is ideal for components exposed to severe wear and impact.
Features
Key advantages of LG600QT:
- ultra-high wear resistance
- high strength and durability
- consistent properties through the plate thickness
- resistance to cracking when properly used
- significantly extended equipment service life
Proper processing procedures are recommended, including preheating and controlled welding conditions.
