IS 2062 E250 Equivalent Grades: ASTM, EN and JIS Standards Compared
IS 2062 E250 is India's most widely used structural steel plate, and procurement teams working on international or multi-standard projects frequently need to know its closest equivalents in other national standards. This guide compares IS 2062 E250 against ASTM, EN, and JIS designations.
What is IS 2062 E250?
IS 2062 E250 is the Indian Standard for hot-rolled structural steel plate, carrying a guaranteed minimum yield strength of 250 MPa, tensile strength of at least 410 MPa, and elongation of 23% minimum. It's produced in sub-grades A, B, and C depending on impact testing requirements, and is commonly referred to in trade simply as 'MS plate.'
ASTM A36: The Closest American Equivalent
ASTM A36 is the most widely cited American equivalent to IS 2062 E250. Both are general-purpose structural carbon steel grades with comparable yield strength (A36 specifies 250 MPa / 36 ksi minimum yield), though the exact chemical composition limits — particularly carbon and manganese content — differ between the two standards. For projects requiring strict ASTM compliance, always specify A36 directly rather than assuming IS 2062 E250 is an automatic substitute.
EN 10025-2 S235JR: The Closest European Equivalent
In the European system, EN 10025-2 S235JR is the closest match, with a minimum yield strength of 235 MPa — slightly lower than IS 2062 E250's 250 MPa. S235JR is impact tested at room temperature (the 'JR' designation), broadly comparable to IS 2062 E250 Grade B. For colder-climate applications, S235J0 or S235J2 (impact tested at 0°C and -20°C respectively) would be closer matches to IS 2062 E250 Grade C.
JIS G3101 SS400: The Closest Japanese Equivalent
In Japan, JIS G3101 SS400 is the standard general-structural steel grade most comparable to IS 2062 E250, with a similar minimum yield strength around 245 MPa depending on thickness. SS400 is widely used in general construction and machinery fabrication, playing a similar market role to IS 2062 E250 in India.
Why You Should Still Verify the Mill Test Certificate
Even though IS 2062 E250, ASTM A36, S235JR, and SS400 all occupy the same general 235-250 MPa yield strength class, they are governed by different chemical composition limits, testing protocols, and tolerance standards. If a project specification calls for one standard by name, don't substitute another without engineering approval — always confirm the actual properties on the Mill Test Certificate rather than relying on the standard name alone.
Conclusion
IS 2062 E250 sits in the same general strength class as ASTM A36, EN 10025-2 S235JR, and JIS G3101 SS400, but each standard has its own chemical and mechanical limits. When a project specifies one standard, source that standard directly rather than assuming automatic interchangeability.
