LG960QT Steel Plate — Ultra-High Strength Quenched and Tempered Steel
General Technical Characteristics
LG960QT steel plate is a high-strength structural steel produced using quenched and tempered (Q&T) heat treatment. It is designed for use under extreme loads and demanding service conditions where maximum strength and reliability are required.
With a yield strength of approximately 960 MPa, LG960QT is an excellent choice for critical and heavily loaded structures. The plate provides high strength, good impact toughness, and resistance to deformation. When proper welding procedures are followed, it also demonstrates good weldability.
Chemical Composition
The chemical composition of LG960QT steel is optimized to ensure maximum strength and wear resistance:
- 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 2.5%
- Molybdenum (Mo) — up to 0.7%
- Microalloying elements (Nb, V, Ti)
These alloying elements improve hardenability, strength, and durability.
Mechanical Properties
LG960QT steel offers the following mechanical properties:
- Yield strength — from 960 MPa
- Tensile strength — 1000–1200 MPa
- Elongation — 10–14%
- High impact toughness, including at low temperatures
These properties ensure reliable performance in structures subjected to dynamic and impact loads.
Applications
LG960QT steel plate is widely used in:
- heavy machinery manufacturing
- crane and lifting equipment production
- mining and quarry equipment
- bridge construction and steel structures
- special vehicles and transport equipment
It is particularly suitable for applications requiring maximum strength with reduced structural weight.
