Main Characteristics and Standards

Material Type: 201, 202, and 304 are all austenitic stainless steels, with 304 being the most common general-purpose grade, offering superior corrosion resistance compared to 201 and 202.

Standards: Angle steel production must conform to ASTM A276 (stainless steel bars and profiles) or ASTM A479 (stainless steel bars and profiles), etc. 304 stainless steel corresponds to UNS S30400 in ASTM standards.

Surface Treatment: Various surface treatments are available, including polishing, brushing, and pickling.

Material Properties
High Strength: For example, the yield strength of Q345B angle steel reaches 345MPa, nearly 50% higher than Q235B (235MPa), enabling it to withstand greater loads.

Corrosion Resistance: Hot-dip galvanizing provides long-lasting protection, suitable for outdoor or corrosive environments, and meets the technical standards for corrosion protection of building steel structures.

Relevant Standards and Processes
Surface Treatment: Hot-dip galvanizing is a common process, requiring Sa2.5 grade rust removal to ensure coating adhesion.

Angle steel is usually made of low-carbon steel such as Q235B and is produced by hot rolling. It is widely used in engineering fields such as construction, machinery manufacturing, iron towers, and curtain walls.

Hot-rolled MS angle steel is a common type of steel used in construction and structures, and it comes in two types: equal-sided angle steel and unequal-sided angle steel. Its material is usually carbon steel (such as Q235B, Q345B), and it conforms to standards including GB, ASTM, JIS, BS, etc.

Specifications and Dimensions

Equal-sided angle steel: Specifications are expressed as "side width × side width × side thickness" (e.g., 90×90×10)

Unequal-sided angle steel: Specifications are expressed as "long side width × short side width × side thickness" (e.g., 150×90×12)

Common size range: Side width 25-200mm, thickness 5-24mm, length typically 6-12 meters

Japanese Standard Angle Steel: Specifications are expressed as side width × side width × side thickness (e.g., 90×90×8), with lengths typically ranging from 6 to 15 meters.

European Standard Angle Steel: Common specifications for equal-sided angle steel include 40×40×3 and 50×50×5, with lengths generally 6 or 12 meters.

Standards Applied: Japanese Standard (JIS), European Standard (EN 10025), Chinese Standard (GB/T 706-2016), etc.

Product Specifications and Standards
