2507 1.4410 Super Duplex Stainless Steel I Beam H Beam IPE HEA HEB Structural Section

2507 / 1.4410 Super Duplex Stainless Steel H-Beams and I-BeamsPeak Kong Special Steel utilizes innovative laser hybrid welding technology and independently developed automated production lines to achieve high-volume, high-precision manufacturing of 2507 / 1.4410 Super Duplex Stainless Steel H-Beams and I-Beams.
Due to its exceptionally high alloy content, Super Duplex Stainless Steel presents significant challenges in conventional hot-rolling processes, including the risk of cracking and the precipitation of detrimental intermetallic phases.
Peak Kong Special Steel applies an innovative laser hybrid welding process as an advanced alternative to conventional hot-rolled manufacturing, successfully overcoming the technical limitations associated with forming large-size and ultra-thick-wall Super Duplex Stainless Steel structural profiles.
The process supports 100% full-penetration welding for ultra-thick weld sections from 30 mm to 50 mm, providing structural continuity and high joint integrity comparable to integrated sections. At the same time, the flexible manufacturing process enables small-batch, multi-size and highly customized production, overcoming the tooling and minimum-volume limitations of conventional hot rolling.
Products can be manufactured in accordance with applicable EN, ASTM, JIS and BS requirements, providing high-performance structural solutions for extreme heavy-load and highly corrosive service environments worldwide.

Material and Engineering Advantages of 2507 / 1.4410 Super Duplex Stainless SteelExceptional Strength and Corrosion Resistance2507 / 1.4410 Super Duplex Stainless Steel combines austenitic and ferritic microstructures with a high alloy content, providing an excellent balance of mechanical strength, toughness and corrosion resistance.
Its high strength-to-weight ratio makes it suitable for heavy-duty structural applications where conventional stainless steel or carbon steel may require larger cross-sections or additional corrosion-protection systems.
Superior Resistance to Chloride and Aggressive EnvironmentsSuper Duplex Stainless Steel provides excellent resistance to pitting corrosion, crevice corrosion and chloride-induced stress corrosion cracking.
This makes 2507 / 1.4410 particularly suitable for:
Seawater exposure
Deep-sea environments
Offshore oil and gas facilities
Marine atmospheric exposure
Chemical processing
Desalination systems
High-chloride industrial environments

Advanced Welding and Microstructural ControlSuper Duplex Stainless Steel requires strict control of welding heat input and thermal cycles to maintain an appropriate austenite-ferrite phase balance and minimize the risk of detrimental intermetallic phase precipitation.
The combination of laser energy concentration and hybrid welding technology enables controlled heat input, high welding precision and reduced distortion, supporting the fabrication of thick-wall structural profiles.
Actual welding parameters, heat input, interpass temperature and post-weld requirements shall be determined through qualified welding procedures according to material thickness, joint configuration and project specifications.
