S355J2 S355J0 C Channel Steel
S355J2 channel steel is a European standard grade equivalent to the national standard Q345D. it is a low alloy high-strength structural steel, because of its good with good impact toughness and welding performance, so this grade of steel in a variety of industries have a wide range of applications. s355J2 parallel flange channel is mainly used for construction, bridges, ships, vehicles, pressure vessels and other structures, the carbon content (smelting analysis) is generally not greater than 0.20%, the sum of alloying elements content is generally not greater than 2.5%, with good impact toughness and welding performance of low alloy steel. 0.20%, the sum of alloying elements is generally not greater than 2.5%, the yield strength is not less than 295MPa, with good impact toughness and welding performance of low alloy steel.
S355J0 metal channel belongs to the European standard carbon steel, the same type of national standard steel corresponding to the Q345B, but the two materials can not be completely replaced, just more like. The latter J0 indicates the impact temperature of the material for the 0 degree impact, the same, J2 is expressed as -20 degrees impact. Steel plate is generally delivered in the state of controlled lashing, normalised or normalised rolling.
