Sheet Steel LG800QT
General Technical Characteristics
Sheet steel LG800QT is a high-strength, wear-resistant steel that has undergone quenching and tempering (QT — Quenched & Tempered). This grade is specifically designed for operation under extreme abrasive wear and heavy mechanical loads.
Its key feature is ultra-high hardness — approximately 800 HB — ensuring maximum wear resistance and significantly extended service life in harsh environments.
The steel is supplied in plate form with thicknesses ranging from 6 mm up to 100 mm and more.
Chemical Composition and Mechanical Properties
LG800QT 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.
Quenching and tempering provide:
- uniform hardness throughout the thickness
- very high strength
- improved impact toughness
- resistance to cracking
Mechanical properties:
- hardness: ~750–800 HB
- yield strength: from 1400 MPa and above
- excellent resistance to abrasive wear
- outstanding resistance to impact loads
Applications
LG800QT is widely used in the most demanding industries:
- mining industry
- quarry and excavation equipment
- buckets, blades, liners
- crushing equipment
- bulk material handling
- metallurgy and heavy machinery
It is ideal for components exposed to extreme wear and impact.
Features
Key advantages of LG800QT:
- maximum wear resistance
- very high strength and durability
- consistent properties across the plate thickness
- resistance to cracking when properly applied
- significantly extended equipment service life
Proper processing requires adherence to welding and cutting procedures (preheating and controlled cooling).
Standards and Supply Formats
LG800QT is produced according to manufacturer specifications aligned with international standards such as EN and ASTM.
Supply formats:
- standard size plates
- cut-to-size plates
- plasma, oxy-fuel, and laser cutting
- custom parts based on drawings
- optional machining services
