NPU
The S235JR U section steel grade is actively used to implement civil engineering solutions. Steel structures are made of S235JR steel for the construction of industrial and residential facilities, parts of power transmission towers, equipment components, offshore structures, oil and gas platforms, automobile bridges and other structures.
Weldability
S235JR grade steel can be welded without restrictions, subsequent heat treatment and heating; However, keep in mind that the higher the product thickness, the higher the risk of cold cracking.
Physical Properties
S235JR is a micro alloy structural steel. mechanical engineering applications. Steel has good weldability with a maximum CEV = 0.47 for all variants. The steel can be delivered with a controlled silicon content for good galvanizing properties. Below are a number of closely related variants with various impact strengths.
