S355G12+N,S355G12+M UC-Universal Columns and beams

We are a steel supplier who understand your offshore project requirement as we manage to decode your need and Erection problems expectation and we are fully experienced in supplying offshore steel material in South East Asia Region.

S355G12+N/G12+M UC-Universal Columns, Beams and other structural sections have low CEV values and are easy to weld. As with all steel types, the selection of weld procedure must take into account a number of factors linked to the properties of the structural sections. The toughness of the HAZ must be kept above critical values to eliminate the https://domelhor.net/scabies-what-to-do.html risk of brittle failure in service. Methods of evaluating the effects of the weld thermal cycle on HAZ hardness and toughness are included in welding standards such as BS EN1011- 2:2001. Data on HAZ toughness (based on Charpy - V impact and Crack Tip Opening Displacement laboratory tests) can be obtained from Beverly Steel on request.

As Rolled Accordance with EN10021

Our Universal Columns and beams will be delivered in the as-rolled condition, in accordance with EN10021. Surface requirements meet EN10163 parts 1 and 3, and rolling tolerances comply with European Specifications, e.g. EN10034 for beams and columns.

High Strength Steels

Beverly Steel would be happy to discuss any requirements for higher strength steels, from the S420 series and above, and any particular requirements for weldability, toughness and mechanical properties. Our steel mill experience in the manufacture of high strength/high toughness grades is well proven together with an extensive knowledge of the demands of the offshore market. Please email us your valued inquiry to us.
