Is S355J2 mild steel?
S355 is supplied in the hot rolled condition as an unalloyed low carbon mild steel grade. The S355J2+N High Tensile Steel specifications are high yield non-alloy steels. For its low carbon equivalent, it possesses good cold-forming properties.
What material is S355J2 N?
Alloy Steel
The EN10025 S355J2 N Low Alloy Steel Plates are made up of carbon, silicon, manganese, sulfur, phosphorus and copper in their composition. The impact values are also high for these plates and it is useful for storage containers and tanks.
What does G3 mean in steel?
S355J2G3 is a non-alloy structural steel according to steel standard EN10025:1990. This standard has now been replaced by EN10025-2:2004 and steels with the S355J2G3 designation are now known as S355J2.J2 means minus 20 centigrade impacting test,G3 means supplying condition and deoxidation measures (Semikilled steel).
What does S355 mean in steel?
structural grade
S355 – a structural grade steel with a minimum yield strength of 355 N/mm²
What does S355J2 mean?
S355J2 is a micro alloyed structural steel suitable for e.g. mechanical engineering applications. The steel may be delivered with a controlled silicon content for good galvanazing properties. Below, a number of closely related variants with various impact strength are presented.
What is the difference between S275 and S355?
S275 provides a lower strength (than S355) but has good machinability and can be welded. The average minimum yield for S275 steel is 275 N/mm² giving its name: S275. S355 steel is a low carbon steel whose specifications offer high yield strength.
What grade of steel is S355?
S355 grade steel is a medium tensile, low carbon manganese steel which is readily weldable and possesses good impact resistance (also in sub-zero temperatures).
What is NL in steel?
+N – normalised +NL – normalised, low notch toughness testing temperature.
What does G mean in steel?
N – Normalised or normalised rolled – P355NL1. Q – Quenched and tempered. G – Other characteristics – P355GH. H – High temperature – P355NH. R – Room temperature.
What is J2 in S355J2?
S355 J2. Grade 50D. 2.0 Sub-Grades JR, J0, J2. Steel sub-grades indicate the Charpy impact value required to prevent brittle fracture. JR – Longitudinal Charpy V-notch impacts 27J at Room temp.
