S355JR Structural Steel & Steel Plate

Steel s355jr characteristics

Steel grade S355JR is used to manufacture hot-rolled flat and long products, which are subsequently used when producing steel building structures.

Classification: Non-alloy structural steel.

Products: Flat and long products, semi-finished products.

The designation "S355JR" means:

S: Structural steel.

355: Min yield strength 355 MPa.

JR: Impact 27 J at +20°C.

It is used for welded structures in standard conditions.

FAQ

What is S355JR equivalent to?

S355JR equivalent grades have very close chemical composition and mechanical properties to that of S355JR steel. Both the S355JR equivalent grades Q345B, A572 Gr 50, ST52-3, SM490B and S355JR steel are main products of BBN steel.

What is structural steel grade S355JR?

S355JR steel has a high strength-to-weight ratio, making it suitable for use in load-bearing structures such as bridges, buildings, and offshore structures. It has a minimum yield strength of 355 N/mm², making it one of the strongest steel grades available.

What is the difference between S355JR and J2?

In S355JR and S355J2 steel, JR and J2 indicates the steel needs to do +20℃ impact test and -20℃ impact test respectively. The different impact temperature is the main difference between S355JR and S355J2 steel. S355J2 steel can better adapt to low temperature work condition than S355JR steel.

What does JR mean in steel?

The J means that the test was conducted with 27 joules of energy. This is followed by either an R for room temperature, or a number referring to the temperature the tests were conducted at. So JR is room temperature (plus 20 degrees) J0 is 0 degrees and J2 is -20 degrees.

Is S355 better than S275?

This grade of steel is stronger than its S275 counterpart with a minimum yield strength of 355 N/mm2 resulting in its S355 name. This grade is also available in plate, round bar, flat bar, and is even available in blocks.

What is the hardness of S355 jr?

Grade S355JR has a minimum yield strength of 355 MPa. The impact energy at a room temperature of 20°C is at least 27 joules.

What is S355 steel used for?

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.

What is the price of S355JR per kg?

Mild Steel, Grade: S355JR – 0.61 USD/kg | 610 USD/ton

What is the difference between S275JR and S355JR?

S275JR is carbon steel, while S355JR is low alloy steel. Both carbon steel S275JR and S355JR low alloy steel are under EN10025-2 standard. The S355JR low alloy steel is higher steel grade than carbon steel S275JR.
