Difference Between IS 2062 and S355J2

IS 2062 vs S355J2 – Why This Comparison Matters

When choosing structural steel plates, IS 2062 (India standard) and S355J2 (European standard) are two of the most widely used grades. While they are functionally similar in many applications, there are key differences in composition, mechanical performance, certification standards, and impact testing.

This comparison is crucial for EPC contractors, OEM fabricators, and government tenders where global compliance and project-specific specs matter.

Quick Summary: Are IS 2062 and S355J2 Equivalent?

Feature	IS 2062 E350	S355J2 (EN 10025-2)
Country of Origin	India (BIS Standard)	Europe (EN Standard)
Yield Strength	350 MPa	355 MPa
Charpy Impact Test	Optional	Mandatory at -20°C (J2)
Silicon Content	Lower	Higher – improves weldability
International Projects	Accepted in India & Asia	Widely accepted for export tenders
Certification Format	IS 2062 + BIS TC	EN 10025-2 + EN 10204 3.1 TC

Though similar in base strength, S355J2 is stricter in terms of impact testing and export compliance. IS 2062 is ideal for domestic cost-effective fabrication

Standard Designations and Grades

• IS 2062: Indian Standard, Grades include E250, E350, E450 with BR / B0 / C suffixes
• S355J2: European Standard EN 10025-2
  • J2 = 27J Charpy impact at -20°C
  • Available as normalized (N) or thermomechanically rolled (TMCP)

Available Sizes & Thicknesses

Parameter	IS 2062 Plate	S355J2 Plate
Thickness	3 mm to 150 mm	3 mm to 100 mm
Width	1250 / 1500 / 2000 / 2500 mm	1500 / 2000 / 2500 mm

How to Choose Between the Two Grades

Ask yourself:

• Is this for an export project? → Use S355J2
• Is cost a deciding factor? → Go with IS 2062
• Does the project require impact-tested steel? → S355J2 preferred
• Are you working with BIS specs? → IS 2062 is mandatory
