S235JRG2 is a low-carbon, non-alloy structural steel that mainly consists of carbon (≤ 0.17%), manganese (≤ 1.4%), phosphorus (≤ 0.04%), and sulfur (≤ 0.04%). This steel grade boasts a minimum yield strength of 235 MPa and a tensile strength that ranges from 360 to 510 MPa. It showcases excellent ductility, cold-forming capabilities, and weldability without requiring preheating. S235JRG2 flanges deliver consistent mechanical performance under typical atmospheric conditions and are well-suited for both welded and bolted flange systems in structural and pipeline applications.
Ismail Flanges, a leading supplier in Indonesia, Jakarta, offers an extensive selection of S235jrg2 Flange, including weld neck flanges, slip-on flanges, blind flanges, threaded flanges, and lap joint flanges. Designed for diverse industrial applications, our high-quality inventory and commitment to exceptional service make us a trusted choice for flange products in the region.
