It is also the lowest priced sub grade and so for maximum economy and availability, JR quality material should be used whenever possible. Higher quality materials, J0Structural Steel EN10025 S275, S355JR and S355JOThe steel should be selected in accordance with the strength requirements.The JR, J0 & J2 suffixes refer to different impact requirements. An average impact energy value of 27 Joules must be achieved on full size specimens in the longitudinal direction in all applicable cases.

The class of steel (JR, J0 or J2) has little or nothing to do with the thickness chosen for a particular design but, on the contrary, for the material thickness selection, the Specified Minimum Yield Strength, has an important role for that purpose. El que Material S355 Steel Properties, Comparison, Equivalent The following letters and numbers explains the steel grade S355 meaning. S is short for structural steel. 355 refers to the minumum yield strength value for the flat and long steel thickness 16mm. JR means the impact energy value is minumum 27 J at room temperature (20). J0 can withstand the impact energy at least 27 J at 0.What is the difference between J2 and JR? Can they be used J2 and JR refer to the materials sub grade its fracture toughness which is measured in joules of a materials toughness at a particular temperature. J2 is a material with a minimum of 27 joules at 20C while JR is a material with a minimum of 27 Joules at +20C (room temperature).. A JR material is normally used in an internal environment whereas a J2 is for external use.
S355J0 is a low carbon, high tensile strength structural steel which can be readily welded to other weldable steel. With its low carbon equivalent, it possesses good cold forming properties.

May 11, 2012· Structural steel is a standard construction material made from specific grades of steel and formed in a range of industry standard cross sectional shapes (or Sections). Structural steel grades are designed with specific chemical compositions and mechanical properties formulated for particular applications.JR , J2, J0, K2 PLEASE EXPLAIN THIS GRADATION WELD I would like to know the difference and meaning of JR, J0, J2, K2 etc which we normally denotes for the steel gradation such as S255J2G3. What is the meaning of G3 too. with best regards Vinu . REJR , J2, J0, K2 PLEASE EXPLAIN THIS GRADATION WELD How to Specify SteelDesign leads to specification JR requires 27J at 20ºC (ie R = room temperature) J0 requires 27J at 0ºC; J2 requires 27J at 20ºC; K2 requires 40J at 20ºC; Thus S275JR corresponds with grade 43B in former terms, and the CVN test may be taken as representative of the steels toughness or resistance to fracture at low temperature.
S235JR and S235L2 act differently when facing blows. J indicates that it can take a hit with a maximum energy of 27 Joules, K 40 Joules and L 60 Joules. R means that the minimum temperature for that capacity is at room temperature (20°C), 0 means 0°C and 2 means 20°C.Structural steel grade designations according to EN Steel group structural steel Mechanical characteristics XXX min. yield strength inMPa example EN 10025 2S 355 J2 + Z35 + M Mechanical characteristics Special requirements notch Z15toughness min. 15%reduction of area min. 27 J min. 40 J Temp. °C JR KR 20 J0 K0 0 Z25 min. 25%reduction of areaHigh Strength Steel New Steel Construction200Table 1 summarises the steel grades and quality covered in the Standards generally cited for building steelwork.

appropriate steel quality or sub grade. The risk depends on a number of contributory factors, including the thickness of the element, the temperature, the state of stress and the type of detail. These factors, and others, are considered in BS EN 1993 1 10, where limiting (maximum) thicknesses of steel are presented for different steel sub Material selection and product specification Steel material is supplied in two product forms flat products (steel plate and strip) and long products (rolled sections, either open beams, angles, etc or hollow sections). For structural use in bridges these products are inevitably cut (to size and shape) and welded, one component to another.In the structure, the material is subject to tensile and compressive forces.MST Steel Corp Steel Material Properties MST Steel CorpApr 02, 2018· The UK National Annex to BS EN 1993 1 1 allows the minimum yield value for the particular thickness to be used as the nominal (characteristic) yield strength f y and the minimum tensile strength f u to be used as the nominal (characteristic) ultimate strength.. Similar values are given for other grades in other parts of BS EN 10025 and for hollow sections to BS EN 10210 1.
