St37-2 is a low-carbon structural steel that meets DIN 17100 standards. Its typical chemical makeup includes about 0.17% carbon, 1.40% manganese, along with trace amounts of phosphorus and sulfur. St37-2 boasts impressive mechanical properties, featuring a tensile strength of 470–630 MPa, a yield strength of around 235 MPa, and an elongation of 20–25%. Its excellent weldability and machinability make it perfect for forming, bending, and fabrication. While it’s not heat-treatable for high strength, it remains a solid choice for moderate-load applications due to its balanced strength, ductility, and ease of processing.
Harsh Flanges, a leading supplier in Mumbai, India, offers an extensive selection of St37-2 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.
