GJ900T Steel Plate — High-Strength Material for Critical Structures
General Technical Characteristics
GJ900T steel plate is a modern high-strength structural steel designed for operation under high loads and intensive wear conditions. This material belongs to the class of steels with a yield strength of approximately 900 MPa, ensuring excellent load-bearing capacity and long service life.
GJ900T plate demonstrates good weldability, resistance to plastic deformation, and stable performance characteristics. Due to the optimal balance between strength and ductility, it is widely used in demanding engineering applications.
Chemical Composition
The chemical composition of GJ900T steel is optimized to achieve high strength and reliability:
- Carbon (C) — up to 0.20%
- Manganese (Mn) — up to 1.70%
- Silicon (Si) — up to 0.60%
- Chromium (Cr), Nickel (Ni), Molybdenum (Mo) — in alloying amounts
- Microalloying elements (Nb, V, Ti)
This balanced composition ensures high strength, wear resistance, and structural stability.
Mechanical Properties
High-strength GJ900T steel offers the following properties:
- Yield strength — from 900 MPa
- Tensile strength — 950–1100 MPa
- Elongation — 10–14%
- High impact toughness
These characteristics make it suitable for structures subjected to dynamic and impact loads.
Applications
GJ900T steel plate is widely used in various industries:
- heavy and transport machinery manufacturing
- lifting equipment and crane production
- construction of steel structures
- mining and agricultural machinery
- production of highly loaded components and assemblies
It is especially востребован where high strength combined with reduced structural weight is required.
