S355 hot rolled carbon structural steel is a medium tensile, low carbon manganese steel which is readily weldable and possesses good impact resistance.
S355 carbon steel is a European standard structural steel, according to EN 10025-2, material S355 is mainly divided into 4 quality grades:
S355JR (1.0045)→Q345B
S355J0 (1.0553)→Q345C
S355J2 (1.0577)→Q345D
S355K2 (1.0596)→Q345E
Chemical properties:
Take S355J2 as an example:
| Grade | C | Si | Mn | P | S | Cu |
| S355J2 | ≤0.22 | ≤0.55 | ≤1.60 | ≤0.025 | ≤0.025 | ≤0.55 |
Mechancal properties:
Take S355J2 as an example:
| Grade | Tensile strength(MPa) | |||
| S355J2 | ＞3mm-≤16mm | ＞16-≤40mm | ＞40-63mm | ＞63-≤80mm |
| 470-630 | 470-630 | 470-630 | 470-630 | |
| Yield strength(MPa) | ||||
| ＞3mm-≤16mm | ＞16-≤40mm | ＞40-63mm | ＞63-≤80mm | |
| ≥355 | ≥345 | ≥335 | ≥325 | |
| Impact energy AKV(J) | ||||
| -20℃，≥27 | ||||
The Carbon structural steel S355 is better than steel S235 and S275 in yield strength, tensile strength and other properties.
The carbon content of S355 hot-rolled carbon structural steel (melting analysis) is generally not more than 0.20%, the total content of alloying elements is generally not more than 2.5%, the yield strength is not less than 295MPa, with good impact toughness and welding properties.
S355 hot rolled carbon structural steel is used in bridges, ships, building structures, cranes and transport machinery, engineering machinery, wind power tower steel structures and other engineering and welded structural members that are subject to high loads.
