S355 S275 Carbon Steel Beam

S355 is a normalizing steel (fine grain steel) in EN10025-3:2004 standard. Its yield strength and tensile strength correspond to the Q345 low alloy steel in ChinaQ275, is a kind of carbon structural steel, with high strength, good plasticity and cutting performance, certain welding performance, small parts can be quenched and strengthened, mostly used in the manufacture of parts requiring high strength, such as gears, shafts, sprockets, keys, bolts, nuts, agricultural machinery steel, conveyor chains and chain joints.

Focus on S275 structural steel

S275 structural steel offers good weldability properties and discrete mechanical characteristics. These qualities are confirmed in its S275 JR version.

The ending JR provides the indication relating to the energy of resilience, where J identifies a minimum energy of 27 J, and the resilience test temperature, equal to 20 degree , is symbolised by the letter R.

S275 corresponds to an unalloyed structural steel for industrial use, supplied in cold drawn sheets, which has characteristics of general suitability for welding.

Focus on S355 structural steel

Structural steel S355 is a non-alloy structural steel, suitable for cold forming on rolls and for edging.

Structural steel S355 J2C + N corresponds to a normalised state of rolling.

The initials J identifies a minimum energy of 27 J.

The acronym 2 in the identification code refers to an impact test temperature equal to -20 degree . The abbreviation C refers to the particular structural use for which it is intended, and the final letter N indicates that the material has undergone a normalised lamination.

This structural steel is used in shipbuilding and railway vehicle construction. S355 steel also finds optimal application for the construction of machinery such as cranes and excavators, as well as in building and piping construction, ventilation systems and pumps.
