Sheet Steel LG700QT / LG700QT/GLC
General Technical Characteristics
Sheet steel LG700QT and LG700QT/GLC are high-strength, wear-resistant steels that have undergone quenching and tempering (QT — Quenched & Tempered). These steels are designed for operation under intense abrasive wear and high mechanical loads.
A key feature is their high hardness of approximately 700 HB, providing excellent wear resistance and long service life in harsh working conditions.
They are supplied in plate form with thicknesses ranging from 6 mm up to 100 mm and more.
Chemical Composition and Mechanical Properties
LG700QT and LG700QT/GLC steels have an alloyed chemical composition including carbon (C), manganese (Mn), silicon (Si), as well as chromium (Cr), nickel (Ni), molybdenum (Mo), boron (B), and other elements.
Quenching and tempering provide:
- uniform hardness throughout the plate thickness
- high strength
- improved impact toughness
- resistance to cracking
Mechanical properties:
- hardness: ~650–700 HB
- yield strength: from 1200 MPa and above
- excellent resistance to abrasive wear
- good resistance to impact loads
Applications
LG700QT and LG700QT/GLC are used in heavy-duty applications:
- mining industry
- quarry and excavation equipment
- buckets, blades, liners
- crushing equipment
- bulk material handling
- metallurgy and heavy machinery
These grades are ideal for components exposed to severe wear and impact.
Features
Key advantages of LG700QT:
- ultra-high wear resistance
- high strength and durability
- uniform properties across the plate thickness
- resistance to cracking when properly used
- significantly extended equipment service life
Proper processing requires adherence to welding and cutting procedures (preheating, controlled cooling).
Standards and Supply Formats
LG700QT and LG700QT/GLC are produced according to manufacturer specifications with reference to 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
