Standards:

The equivalent materials corresponding to each country are as follows:

1. "S355JR" is a carbon structural steel of European standard EN 10025-2:2004;

2. "Q345B" of Chinese Standard GB/T 1591-2008 "Low Alloy High Strength Structural Steel";

3. "S355B" of ISO 630-2:2011 of the International Organization for Standardization.

S355JR Core Advantages Analysis
Compared to ordinary Q345 steel, S355JR excels in the following aspects:
• Low-temperature toughness: By adding trace amounts of elements such as niobium and vanadium to refine the grain size, the impact energy can remain above 20J at -20°C.
• Weldability: Carbon equivalent (CEV) ≤ 0.43%, significantly reducing the risk of cold cracking.
• Dimensional stability: The TMCP process is used during hot rolling to control residual stress.

Chemical Composition

S355JR is a low-carbon alloy structural steel, whose chemical composition contains appropriate amounts of silicon, manganese, phosphorus, sulfur and other elements. These elements have a positive impact on the strength, plasticity and toughness of the steel.
