How to form S355K2G2W plates successfully—bend radii, springback, temperature, grain direction, and practical shop-floor guidance.
How to cut S355K2G2W plates correctly—plasma, oxy-fuel, laser, and shearing methods with practical guidance for each process.
How to weld S355K2G2W successfully—filler selection, heat control, preheat, and preserving patina performance in the weld zone.
Both grades have the same strength and impact toughness. What's the difference?
S355K2G2W is a weathering steel grade under the European standard EN 10025-5. It belongs to a family of steels designed to resist atmospheric corrosion without needing paint or protective coatings. Instead of fighting rust, it uses rust to its advantage.
Steel standards don't stay still. They evolve. If you've been specifying S355K2G2W for years, you might have noticed changes in certificates and grade references. Here's what shifted between the old and new European standards—and what it means for your
