The next set of 3 digits gives the steels minimum yield strength. So S355 has a minimum yield strength of 355 MPa for the smallest thickness range covered by the relevant standard i.e. EN10025. These are the basics. You can then have up to 3 groups of characters providing more information. Ductility limits of high strength steelsto propose an efficient virtual testing platform for a fast and effective introduction of new steels and steel products to the market. The main practical objective is to use the platform to develop recommendations of the material ductility requirements in the Eurocodes for high strength steels.
The yield strength, f y, and the ultimate tensile strength, f u, for hot rolled structural steel and structural hollow sections at room temperature are given in the product standards EN 10025, EN 10210 and EN 10219 respectively. Simplifications are given in Tables C.1 and C.2, which are taken from EN 1993-1-1.

According to GB/T 1591 -2018, Q355 has 3 quality levels:Q355B, Q355C and Q355D. Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Strength, 355 is the minimum value of yield strength 355 MPa for steel thickness 16mm, and tensile strength
Strength  Yield strengtYield strength is the most common property that the designer will need as it is the basis used for most of the rules given in design codes.In European Standards for structural carbon steels (including weathering steel), the primary designation relates to the yield strength, e.g. S355 steel is a structural steel with a specified minimum yield strength of 355 N/mm². Structural Steel - BS EN 10025 S355 and S275S355 steel is a low carbon steel whose specifications offer high yield strength. The average minimum yield for S355 steel is 355 N/mm² giving its name:S355. BS EN 10025 S275 & S275JR supercedes BS4360 43A and 43B. S355 sheet/plate can also be flame cut to a profile on request. Structural Steel - S235, S275, S355 Chemical Composition May 11, 2012 · 235 which relates to the minimum yield strength of the steel (tested at a thickness of 16mm); S355J2+N/M is the direct EN equivalent of ASTM A572 GR 50. One of our contractors claims that S235 is the standard material used for most industrial steel profiles ans if one wants S355 - it will require a special order with long lead
Our product portfolio also includes structural grade carbon steel according to DIN EN 10025-2. Among them, the grades S235JR to S500J0 as well as S185, S295 E355 and E360 are integrated.
