S275 Data Sheet & Specification. EN 10025 S275 steel properties, composition and equivalent materials can be found in the following datasheet. Is S275 obsolete?Is S275 obsolete?S275 is not an obsolete grade and is still a mainstay in the construction industry perhaps even more so than S355 material. S355 is a higher grade of material compared to S275 and therefore there is a cost difference between the two grades.Structural Steel - S235, S275, S355 Chemical Composition s275 impact test at 50 deg What does EN10025 s275jr mean?What does EN10025 s275jr mean?EN10025 S275JR Meaning (Designation) The lists below explains EN10025 S275JR meaning S is for structural steel; 275 refers to the minimum yield strength is 275 MPa tested with steel thickness 16mm.

In the above example, your MDMT is -27 degree F, and in the UCS 66 table, the minimum permissible temperature without impact testing designated -26 degree F. So with this clause you can reduce it to -36 degree F(-26 -8 = -34). Your MDMT is -27 degree F, so you are exempted from impact testing with this clause.
