S355 Carbon Steel Plate

1. Material Overview

S355 is a low-alloy high-strength structural steel defined by the European standard EN 10025-2:2004, widely used in industrial and construction applications. The designation means:

 

S: Structural steel

355: Minimum yield strength of 355 MPa (for thickness ≤16mm)

Grades are classified by impact toughness requirements (e.g., JR, J0, J2, K2), corresponding to impact performance at different temperatures (e.g., JR: 20°C, J2: -20°C).

 

 

 

 

 

2. Application Fields

Construction: High-rise buildings, bridges, industrial plants, and large-span structures (e.g., stadiums, airport terminals).

Mechanical Manufacturing: Frames for heavy machinery, crane structures, and mining equipment components.

Energy Sector: Wind turbine towers, pressure vessels, and power station steel structures.

Transportation: Vehicle chassis and railway vehicle components.

3. Comparison with Other Grades

Grade	Yield Strength (MPa)	Impact Temperature/Energy	Typical Applications
S235JR	≥235	20°C ≥27J	Low-load structures (e.g., small components)
S355JR	≥355	20°C ≥27J	Medium-load structures (bridges, factories)
S355J2	≥355	-20°C ≥27J	Low-temperature structures (e.g., northern buildings)
S420JO	≥420	0°C ≥34J	High-strength structures requiring low-temperature impact resistance
