Manufactured under IS 1161:2014 Grade YST 310 (310 MPa min. yield), Kamdhenu YST 310 80 NB MS CHS - (88.9 x 4.8 mm) - 6 mtr Length is a precision-formed MS CHS offering uniform hoop strength, equal biaxial bending resistance, and superior torsional stiffness for high-load structural columns, heavy fluid transport, and demanding industrial applications. The 88.9 mm outer diameter × 4.8 mm wall section in 80 NB bore and 6 m standard mill lengths provides 450 MPa tensile strength with ≥ 15% elongation.

• Grade YST 310 to IS 1161:2014 — maximum strength grade in the IS 1161 CHS range
• High yield strength enables reduced section size for weight-optimised structural design
• Equal bending resistance in all orientations eliminates orientation-sensitive connection design
• Excellent stiffness-to-weight ratio for column, strut, and compression member applications
• Suitable for bolted flange plate connections and full-penetration butt-welded joints

• High-pressure process water lines in steel plants, refineries, and chemical plants
• Offshore and marine structural members, jacket piles, and riser supports
• Bridge approach structure circular columns and pylon base members
• Stadium primary roof columns, large-span truss nodes, and canopy supports
• Seismic-resistant structural frames and energy-absorbing circular column members
