S460ML TMCP Offshore Steel Coil 3-20mm Wind Power Tower 460MPa Yield EN 10025-4

The S460ML thermomechanically rolled steel coil is specified for welded structures that carry high loads in cold and offshore environments. Zhengde produces the grade with controlled rolling followed by accelerated cooling, which refines the ferrite grain and delivers a guaranteed 460 MPa yield strength together with 27 J Charpy impact energy at minus 50 degrees C. The low carbon equivalent keeps the steel weldable with normal shop procedures, and the uniform through-thickness properties simplify the rolling and welding of conical wind tower sections. Supply covers 3mm to 20mm thickness and 900mm to 2000mm width, with mill finish or pickled surfaces. Every coil end is tested for tensile and impact performance, and EN 10204 3.1 certificates give fabricators and engineering consultants the verified data required for design release.

• Guaranteed Low Temperature Toughness Fine grain TMCP microstructure delivers 27 J Charpy energy at -50 degrees C, meeting the demanding requirements of cold climate and offshore service
• High Strength with Low Alloy Cost 460 MPa minimum yield enables thinner tower shell plates and tubular sections, cutting welding volume and total steel weight
• Excellent Weldability Low carbon equivalent supports high heat input welding with reduced preheat, improving productivity in tower and jacket fabrication shops
• Uniform Properties Through Thickness Controlled rolling and accelerated cooling keep strength stable across strip width, simplifying forming of conical tower sections
• Good Formability The material bends and rolls cleanly into cans and tubulars without surface cracking, even at low workshop temperatures
• Project Documentation EN 10204 3.1 certificates with full mechanical test data support design verification and client approval

S460ML is specified for welded structures that combine high load with low temperature service: onshore and offshore wind power tower sections, transition pieces and flanges, offshore platform topsides and jackets, crane structures, penstocks, lock gates, bridges and mining equipment. Its TMCP delivery condition is increasingly preferred by fabricators who need dependable toughness without post weld heat treatment.

Every coil end is tested for yield, tensile, elongation and Charpy impact at -50 degrees C, with results reported on EN 10204 3.1 certificates. Zhengde is ISO 9001:2015 certified and works with SGS, BV and TUV for third-party witnessing. Seaworthy packaging with rust protection is standard, and delivery is 7-15 days for stock items and 20-30 days for production orders.
