S355J2H Hot Finish EN 10210 Square Hollow Section
Ranfit Metal is a well-known manufacturer, supplier, and stockiest of Hot Finish ASTM A500 Gr. C Square Hollow Section. The hot finish process involves heating the Hot Finished ASTM A500 Gr. C SHS to a temperature above 1,600°F (871°C), followed by rapid cooling to achieve a fine-grained microstructure that enhances the material's strength, toughness, and weldability.
Hot Finish ASTM A500 Gr. C Square Hollow Section is High strength-to-weight ratio, which enables the design of lightweight structures without compromising on strength. Hot Rolled ASTM A500 Gr. C Seamless Square Hollow Sections is excellent weldability and formability, making it easy to fabricate complex shapes and structures. Good corrosion resistance, which reduces the need for additional coatings or protective treatments and also Low maintenance requirements, as the material is resistant to scaling and rust. The 'Gr. C' designation in ASTM A500 Gr. C Hot Finish Welded SHS signifies that the steel alloy used in the production of this hollow section has a minimum yield strength of 50,000 psi (345 MPa), making it an ideal choice for load-bearing applications where high strength-to-weight ratios are essential. Due to their high strength and durability, ASTM A500 Grade C square hollow sections offer a cost-effective solution for construction projects.
The Hot Finish ASTM A500 Gr. C SHS Tubing is widely used in various applications, such as Building frames and structures,,Bridge construction, Industrial equipment and machinery, Vehicle chassis and frames, Furniture and fixture manufacturing, Architectural features and decorative elements etc.
ASTM A500: is the most common specification in North America for Hollow Structural Sections (HSS).
Gr. C: Minimum yield strength of 33 ksi (227 MPa) and minimum tensile strength of 45 ksi (310 MPa).
