EN10210 S355K2H Hot Finished CHS Hollow Sections

SS355K2H Hot Finished, fully comply with EN standard, EN10210 S355K2H hot formed. Available in RHS-Rectangular Hollow Section, SHS-Square Hollow Section and lupo italiano CHS-Circular Hollow Sections, free of internal stresses and with a minimum strength of 355 MPa, allowing the highest fabrication factors and enabling material cost savings and lighter structures, impact tested -20 degree C at 40Joules suitable for low temperature applications. We supply wide range of sizes, odd sizes and super big sizes from various countries of origin.

Application : Deep Water Projects, Power Plants, Offshore Oil and Gas Projects, Structural Design Arts for Buildings and Towers, Structural Support for Building and Facilities Expansion, MRT-Mass Rapid Transit, MTR-Mass Transit Railway, Terminals, Stations, Sea Port Facilities, Air Port Facilities, Transport Vehicles, Theme Parks, Structural for Theme Park Rides and etc...

a.The deoxidation methods are designated as follows.

FN = Rimming steel not permitted

FF = Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen

(e.g. min. 0.020 % total Al, or 0.015 % soluble Al).

b. It is permissible to exceed the specified values provided that for each increase of 0.001 % N the P max. content is also reduced by 0.005%. The N content of the cast analysis. however, shall not be more than 0.012 %.

c. The maximum value for nitrogen does not apply if the Il trattamento dei sintomi di impotenza provoca trattamento per la disfunzione erettile negli uomini chemical composition shows a minimum total Al content of 0.020 % with a minimum

Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document
