IS 2062 E250 Mild Steel Plates: Complete Guide for Structural & General Engineering
IS 2062 E250 is the most widely used structural mild steel plate in India, forming the backbone of general construction, storage tanks, machinery frames, and fabrication work nationwide. This guide covers what E250 is, its sub-grades, mechanical properties, and how to buy it with confidence.
What is IS 2062 E250?
IS 2062 E250 is a hot-rolled structural steel plate governed by the Bureau of Indian Standards. The 'E250' designation signifies a guaranteed minimum yield strength of 250 MPa, sufficient for the vast majority of conventional building frames, machinery bases, and general engineering fabrication across India. It is commonly referred to in the trade simply as 'MS plate' or 'mild steel.'
Understanding Grades A, B, and C
IS 2062 E250 is available in three sub-grades that differ in impact testing requirements. Grade A requires no impact testing and is suited to non-critical, ambient-temperature applications. Grade B is impact tested at room temperature (approximately 20°C), offering assured toughness for standard structural use. Grade C is impact tested at 0°C, making it the preferred choice for structures operating in cooler climates or subject to dynamic loading.
Chemical Composition & Mechanical Properties
Carbon content is capped between 0.20% and 0.23% depending on sub-grade, with manganese up to 1.50%, and phosphorus and sulphur tightly controlled below 0.045%. Mechanically, all sub-grades deliver a minimum yield strength of 250 MPa, tensile strength of at least 410 MPa, and elongation of 23% minimum — properties that give E250 its excellent combination of strength and ductility for cold forming and welding.
Applications Across Industry
IS 2062 E250's versatility makes it the go-to structural grade for general construction, storage tanks, bridges, automotive chassis components, and machinery frames. Its excellent weldability and formability mean it can be fabricated using standard workshop equipment without specialised procedures, keeping project costs predictable.
Buying IS 2062 E250: What to Check
When sourcing E250 plates, always confirm the sub-grade (A, B, or C) matches your project's toughness requirements, and insist on a Mill Test Certificate from a reputable producer such as SAIL, JSPL, JSW, or AM/NS. Since bare mild steel oxidises readily, plan for painting, priming, or galvanizing if the plates will be exposed outdoors for extended periods.
Conclusion
IS 2062 E250 remains the workhorse structural steel for Indian fabrication, offering an unbeatable combination of cost-effectiveness, weldability, and reliable strength.
