With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Yield Strength. The yield strength of structural steel measures the minimum force required to create a permanent deformation in the steel. The naming convention used in European Standard EN10025 refers to the Minimum Yield strength of the steel grade tested at 16mm thick.

S275JR 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. The plate is produced by fully killed steel process and supplied in normalized or controlled rolling condition.
EN 1.0044 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the hot worked condition. 1.0044 is the EN numeric designation for this material. S275JR is the EN chemical designation.
Nominal values of structural steel yield strength and ultimate strength. For structural design according to Eurocode 3 (EN1993-1-1), the nominal values of the yield strength f y and the ultimate strength f u for structural steel are obtained as a simplification from EN1993-1-1 Table 3.1, which is reproduced above in tabular format.
S275 & S275JR steel can be supplied in plate, round bar and flat bar. 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/mm giving its name: S275.
S355 Yield Strength S355 is named based on it's minimum yield strength of 355 Mpa (N/mm2), However the yield strength reduces when you go up in thickness above 16 mm for flat products & hollow sections Here is the table showing reduction in yield strength based on thickness Up to 16 mm - 355 Mpa 16 mm < t 40 mm - 345 Mpa
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/mm.
Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or Ftu within equations, is the capacity of a material or structure to withstand loads tending to elongate, as opposed to compressive strength, which withstands loads tending to reduce size.
ASTM A36 (SS400, S275) Structural Carbon Steel ASTM A36 carbon steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition.

S275 is an unalloyed low carbon mild steel grade supplied as hot rolled. As a low carbon steel specifications S275 provides low strength with good machinability and is suitable for welding.

S275 structural steel plate is a common carbon structural steel with minimum yield strength of 36 ksi, it bears many similarities to ASTM A36 in both chemistry and physical properties.[PDF] MECHANICAL PROPERTIES OF MATERIALS - MIT. 1.1.

In most countries, structural steel is regulated and must match a minimum specific criterion for chemical composition, shape, size, strength etc. Chemical Composition of Structural Steels - S235, S275 and S355. The chemical composition of structural steel is very important and highly regulated.
Materials - Carbon Steel Bolts in ASTM A307 (Grades A and B) Scope ASTM A307 is the standard specification for carbon steel bolts, studs, and threaded rods of 60000 PSI tensile strength in sizes from inch to 4 inches in diameter.
The material selection menu for the actual strength levels and grades is shown in table 1. All listed MDS are enclosed. 4.2 Selection Criteria The number of steel grades used in a project should be limited to the practical minimum. An evaluation should be carried out to determine the optimum grades.
The BHN can be converted into the ultimate tensile strength (UTS), although the relationship is dependent on the material, and therefore determined empirically. The relationship is based on Meyer's index (n) from Meyer's law. If Meyer's index is less than 2.2 then the ratio of UTS to BHN is 0.36.
The studied materials were common structural steel grades with nominal yield strength varying from 350N/mm2 to 460N/mm2. The actual yield strength varied significantly from the nominal values and this has to be taken into account. The materials are listed in the Table 1 below with the nominal and measured values at room temperature.
require modification for the higher strength steels. BS EN 1993-1-12 relaxes the minimum required ratio of the ultimate tensile strength to the yield strength ( u / y) to 1.05 (compared to 1.1 for conventional strength steels) and the elongation at failure is only required to exceed 10% (compared to 15% for conventional strength steels).
The achievement of a suitable strength whilst maintaining other properties has been the driving force behind the development of modern steel making and rolling processes. In the CEN product standards, the primary designation relates to the yield strength, e.g. S355 steel is a structural steel with a minimum yield strength (R eH) of 355 N/mm 2 s275jr ultimate strength
#S275JR and its related series (S275J0, S275J2, S235JR, S235J0, S235J2) are very versatile common mild steel/carbon steel plate for multiple structural applications e.g. manufacturing plant, machinery, mining equipment and vehicles, excavators, loader, bulldozers, crane, mining hydraulic supports, construction, power plant, sugar mill, palm oil s275jr ultimate strength
Plates thicker than 8 in have a 32,000 psi (220 MPa) yield strength and the same ultimate tensile strength of 58,00080,000 psi (400550 MPa). The electrical resistance of A36 is 0.142 m at 20 C. A36 bars and shapes maintain their ultimate strength up to 650 F (343 C).
1 MPa = 1N/mm 2 Note. For all products to be compliant with the EU Construction Products Directive (CPD 89/106/EC) the material must offer a guaranteed minimum impact performance.
The compressive strength of mild steel is 4.75 25.2 tonnes / sq. cm. Its ultimate tensile strength is 5.51 11.02 tonnes / sq. cm. This clearly shows that mild steel is a better option than cast iron when it comes to ultimate tensile strength. However, cast iron has better compressive strength than mild steel. Get Price
