Sheet Steel LG700 / 700T / 700TE / 700T-GJ
General Technical Characteristics
Sheet steel grades LG700, 700T, 700TE, and 700T-GJ are high-strength, wear-resistant steels designed for operation under extreme loads and intensive abrasive wear.
These steels are characterized by high strength and hardness:
- LG700 — enhanced strength and wear resistance
- 700T / 700TE / 700T-GJ — improved versions with specialized performance properties
TE and GJ modifications provide increased impact toughness, crack resistance, and better weldability.
The steel is supplied in plate form with thicknesses ranging from 6 mm up to 100 mm and more.
Chemical Composition and Mechanical Properties
LG700 and 700T series steels have an alloyed composition including carbon (C), manganese (Mn), silicon (Si), and alloying elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), boron (B), and others.
This composition ensures:
- high strength
- excellent wear resistance
- resistance to impact loads
- stable properties during service
Mechanical properties:
- yield strength: from 700 MPa and above
- high hardness (depending on the modification)
- increased resistance to abrasive wear
- good impact toughness (especially TE and GJ)
Applications
LG700 / 700T / 700TE / 700T-GJ steels are widely used in the most demanding conditions:
- mining industry
- quarry and construction equipment
- buckets, blades, liners
- crushing equipment
- bulk material handling
- metallurgy and heavy machinery
These steels are ideal for components exposed to extreme loads and wear.
Features
Key advantages of LG700 steel:
- very high strength and wear resistance
- resistance to impact loads
- extended service life of equipment
- possibility to reduce plate thickness and structure weight
- improved properties in TE and GJ modifications
Processing requires adherence to proper welding and cutting procedures (preheating, controlled cooling).
Standards and Supply Formats
LG700 and 700T steels 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
