LG900QT Steel Plate — Quenched and Tempered High-Strength Steel
General Technical Characteristics
LG900QT steel plate is a high-strength structural steel produced using quenched and tempered (Q&T) heat treatment. It is designed for operation under extreme loads where a combination of high strength, toughness, and reliability is required.
With a yield strength of approximately 900 MPa, LG900QT is ideal for critical and load-bearing structures. The plate offers good weldability (with proper procedures), high resistance to deformation, and long service life, making it suitable for demanding engineering applications.
Chemical Composition
The chemical composition of LG900QT steel is optimized to ensure strength and structural stability:
- Carbon (C) — up to 0.20%
- Manganese (Mn) — 1.0–1.7%
- Silicon (Si) — up to 0.60%
- Chromium (Cr) — up to 1.5%
- Nickel (Ni) — up to 2.0%
- Molybdenum (Mo) — up to 0.7%
- Microalloying elements (Nb, V, Ti)
These alloying elements enhance hardenability, strength, and wear resistance.
Mechanical Properties
LG900QT high-strength steel provides the following mechanical properties:
- Yield strength — from 900 MPa
- Tensile strength — 950–1200 MPa
- Elongation — 10–15%
- High impact toughness, including at low temperatures
These characteristics ensure reliable performance under dynamic and impact loading conditions.
Applications
LG900QT steel plate is widely used across various industries:
- heavy machinery manufacturing
- crane and lifting equipment production
- mining and quarry machinery
- bridge construction and steel structures
- special vehicles and transport equipment
It is especially suitable for structures requiring high strength combined with reduced weight.
