Description
Produced to IS 1161:2014 Grade YST 355 by the ERW manufacturing process, the Hi-Tech Pipes MS CHS Hi-Tech YST 355 40 NB MS CHS (48.3 x 1.6 mm) - 6 mtr Length offers a 48.3 mm outer diameter, 40 NB nominal bore, and 1.6 mm wall thickness in standard 6 m lengths. This circular hollow section meets minimum yield of 355 MPa and tensile strength of 490 MPa for reliable use in medium-duty structural columns, industrial frames, and mechanical/structural tube applications. The round closed profile eliminates stress concentration at corners and provides a consistent section modulus in all planes, making this tube an efficient and aesthetically preferred choice for structural columns and exposed steel frames.
Key Features:- IS 1161:2014 Grade YST 355 compliant with traceable mechanical test certificates
- ERW process with controlled heat input ensuring uniform weld zone properties
- Certified yield strength of 355 MPa for structural engineering design calculations
- Isotropic circular profile providing equal load resistance in all planes
- Consistent wall thickness around the full tube circumference for uniform stress distribution
- Clean mill surface finish receptive to all protective coating and galvanizing systems
- Standard 6 m cut lengths minimising on-site material wastage and splice frequency
- Compatible with conventional bolted flange, welded, and mechanical fastening systems
- Low carbon equivalent supporting excellent field weldability and site fabrication
