Key Specifications and Composition

Standards

Compliant with JIS G3114 (Weathering Steels for Rolled Steel Plates, Sheets, and Strips).

Often equivalent to international standards like ASTM A242 (High-Strength Low-Alloy Structural Steel with 5% Chromium for Atmospheric Corrosion Resistance) or ISO 4553 (Weathering Steels).

Chemical Composition (Typical Values, wt%)

 

 

 

Key Features

Natural Corrosion Resistance

Forms a dense, adherent patina layer (composed of iron oxides like FeOOH) that acts as a barrier, preventing deeper rust penetration.

Reduces maintenance needs (e.g., painting) by up to 50% compared to conventional carbon steel in corrosive environments (e.g., industrial areas, coastal zones, or regions with high humidity).

High Strength and Workability

Equivalent to low-alloy high-strength steels (e.g., ASTM A588) in tensile strength.

Can be cut, welded, and formed using standard industrial processes (e.g., plasma cutting, arc welding).

Aesthetic Appeal

The matured patina develops a uniform, rust-colored appearance, often used in architectural applications for its industrial aesthetic (e.g., sculptures, building facades).
