ASTM A514 Grade J Steel Plates – High Strength Structural Alloy Steel
Conquest Steel & Alloys are a prominent supplier of ASTM A514 Grade J Steel Plates, which are known for their high yield strength, toughness, and wear resistance. Engineered to serve in challenging structural conditions, these plates undergo quenching and tempering to achieve the mechanical properties of the ASTM A514 standard.
A514 Grade J provides a minimum yield strength of 690 MPa (100 ksi) and is applicable for heavy load and harsh environment applications. Its high strength-to-weight ratio, formability, and weldability make it the material of choice in construction, mining machinery, cranes, and offshore platforms.
Main Features:
- Minimum yield strength of 690 MPa
- Excellent low-temperature toughness
- Good weldability and machinability
- Good resistance to fatigue and impact
- Lower plate weight for structural efficiency
In thicknesses of 6mm to 100mm, our ASTM A514 Grade J Plates are provided with full documentation, including MTCs and third-party inspection availability.
