❓ Frequently Asked Questions
What does the "J2" stand for in EN S355J2?
"J2" indicates that the steel has been impact tested at -20°C with a minimum energy absorption value of 27 Joules, ensuring toughness in cold environments.
Is S355J2 weldable without preheating?
For standard plate thicknesses (up to 20-30mm), S355J2 can usually be welded without preheating, but thicker plates may require a low-level preheat according to engineering standards.
What are the equivalents of S355J2 in other standards?
The most common equivalents are ASTM A572 Grade 50, JIS SM490, and GB Q355D.
What is the maximum thickness of S355J2 plate you can provide?
We can supply EN S355J2 plates with thicknesses ranging from 6mm up to 300mm to accommodate various heavy engineering needs.
Do you provide Ultrasonic Testing (UT) for S355J2?
Yes, we can perform Ultrasonic Testing (e.g., Level S1, S2 per EN 10160) for critical structural applications to ensure the plate's internal soundness.
