What is SS400 grade material?
SS400 is a hot rolled steel grade belonging to the JIS G 3101 standard. SS400 Plates are designed with a superior concentration of ferrous material with small constituents of silicon, carbon, sulfur, and phosphorous.
Is SS400 carbon steel or stainless steel?
JIS G3101 SS400 is one of the most common carbon structural steel grade, other grades of JIS G3101 are ss330, ss490, ss540.
Is SS400 equivalent to mild steel?
Key Insight: SS400 prioritizes tensile strength over elongation compared to mild steel. Strength vs. Ductility: SS400 has a higher tensile strength (400+ MPa) but slightly lower ductility than mild steel. Regional Use: SS400 aligns with Japanese standards, while ASTM A36 (USA) or S235 (EU) are regional equivalents.
What does SS400 stand for?
SS400 steel is a low-carbon structural steel defined under the JIS G3101 standard, primarily used in general construction and engineering applications. The "SS" stands for "Steel Structure," and the "400" indicates a minimum tensile strength of 400 MPa, making it suitable for non-critical load-bearing components.
What is equivalent to SS400?
Equivalent materials to the widely used SS400 include ASTM A36 and EN S275JR, both of which exhibit similar mechanical properties and are often utilized in similar applications.
