Products Description
S355J0 Carbon Steel Hot Rolled Sheetis a medium-carbon, low-alloy structural steel that meets the EN 10025-2 standard. Known for its high strength, excellent toughness, and outstanding weldability, it is widely used in construction, machinery manufacturing, and transportation industries.
It has a minimum yield strength of 355 MPa, a tensile strength of 470–630 MPa, and elongation ≥ 20%, providing stable performance under dynamic loads and harsh environments. Its good impact toughness ensures safety and reliability even under low-temperature or high-impact conditions.
S355J0 corresponds to several international steel grades, including ASTM A572 Grade 50, DIN St52-3, JIS SM490, and GB/T Q345B, making it suitable for cross-regional projects and material substitution.
The steel plates can be welded, cut, bent, and machined into various structural components and support elements, meeting the diverse needs of construction, machinery, and industrial equipment applications.
