Products Description
| Grade | Chemical Composition | Mechanical Properties | Characteristics and Applications |
|---|---|---|---|
| CCSA | C ≤ 0.21%, Mn ≥ 2.5C, Si ≤ 0.5%, S ≤ 0.035%, P ≤ 0.035% | Yield strength σs ≥ 235 MPa, Tensile strength σb: 400 - 520 MPa, Elongation σ% ≥ 22 | Good comprehensive performance. Used for general parts of ship hull structures in ocean-going, coastal and inland navigation areas, such as hull shells and decks of some small ships. |
| CCSB | C ≤ 0.21%, Si ≤ 0.35%, Mn: 0.80 - 1.20% (lower limit of Mn can be 0.60% when doing impact test for grade B steel), S ≤ 0.035%, P ≤ 0.035% | Yield strength σs ≥ 22 MPa, Tensile strength σb: 400 - 520 MPa, Elongation δ/% ≥ 22, Test temperature: 0℃ | Slightly lower strength and toughness compared to CCSA. Commonly used in ship parts with lower strength requirements, such as internal structures and non-major load-bearing parts. |
| CCSD | C ≤ 0.21%, Mn ≥ 0.60%, Si ≤ 0.35%, S ≤ 0.035%, P ≤ 0.035% | Yield strength σs ≥ 235 MPa, Tensile strength σb: 400 - 520 MPa, Elongation σ% ≥ 22 | Has certain improvement in strength and toughness. Suitable for ship structures with higher requirements for steel performance, such as hull shells and main decks of large ships, able to withstand larger loads and stresses. |
| CCSE | C ≤ 0.18%, Mn ≥ 0.70%, Si ≤ 0.35%, S ≤ 0.035%, P ≤ 0.035% | Yield strength σs ≥ 235 MPa, Tensile strength σb: 400 - 520 MPa, Elongation σ% ≥ 22 | Has high strength and good toughness. Can be used for key ship structures with higher requirements for steel performance, such as bow, stern, and cargo tank areas of large oil tankers, able to adapt to harsh marine environments and complex load conditions. |
