I. S275J0 High-Strength Low-Alloy Steel Plate

1. Standard and Grade Interpretation

Standard: European standard EN 10025-2:2004, classified as low-alloy high-strength structural steel.

Grade Meaning:

S: Structural steel.

275: Yield strength ≥275 MPa (for thickness ≤16 mm).

J0: Impact performance grade (longitudinal impact absorption energy ≥27 J at 0°C, transverse ≥20 J).

 

II. S355J0 High-Strength Low-Alloy Steel Plate

1. Standard and Grade Interpretation

Standard: Same as S275J0 (EN 10025-2:2004), belonging to fine-grain low-alloy high-strength structural steel.

Grade Meaning:

355: Yield strength ≥355 MPa (for thickness ≤16 mm).

J0: 0℃ impact performance grade (same as S275J0).

III. A514 High-Strength Low-Alloy Steel Plate (U.S. Standard)

1. Standard and Grade Interpretation

Standard: American ASTM A514/A514M, classified as quenched and tempered high-strength low-alloy steel plate, commonly known as "quenched and tempered high-strength steel for structural use".

Grade Meaning:A514: Standard number, corresponding to different grades (e.g., Grade B, Grade F, etc.). Take Grade B as an example:

Yield strength ≥690 MPa, tensile strength 795–930 MPa.

IV. A517 High-Strength Low-Alloy Steel Plate (U.S. Standard)

1. Standard and Grade Interpretation

Standard: ASTM A517/A517M, belonging to the same quenched and tempered high-strength steel category as A514, with a focus on high tensile strength and fatigue resistance.

Grade Classification: Grades such as Grade A, Grade B, Grade F, etc. Take Grade F as an example:

Yield strength ≥690 MPa, tensile strength 795–930 MPa.
