Advantage

Compared with ordinary strength steel, high-strength steel has higher yield strength and tensile strength. Therefore, using high-strength steel components instead of ordinary strength steel components can reduce cross-sectional size, save steel consumption, and reduce manufacturing, transportation, and installation costs. The application of high-strength steel not only reflects higher structural efficiency, but also brings considerable economic and social benefits.
There are many advantages of high-strength steel, and research results show that under the same axial compression conditions, steel columns made of high-strength steel have ultimate stress in terms of overall stability δ The ratio of u to yield strength fy δ U/fy (i.e. overall stability coefficient) φ）， It is much higher than ordinary strength steel columns. Compared to ordinary steel, the use of high-strength steel in steel structures has the following advantages: it can reduce component size and structural weight, correspondingly reduce welding workload and welding material usage, reduce the use of various coatings (such as rust prevention and fire prevention), make transportation and installation easier, and reduce the processing, manufacturing, transportation, and installation costs of steel structures. High strength steel can reduce the amount of steel used, thereby greatly reducing the consumption of iron ore resources; The reduction of the amount of welding materials and various coatings (rust prevention, fire prevention, etc.) can also greatly reduce the consumption of non Renewable resource and reduce the damage to the environment caused by resource exploitation.

Product Details

S355 grade steel is a medium tensile, low carbon manganese steel which is readily weldable and possesses good impact resistance (also in sub-zero temperatures).

This material is commonly supplied in the untreated or normalised condition and is available in several variations (denoted by additional letters and/or digits) which offer slight modifications of chemical composition and mechanical properties.

Machinability of this material is similar to that of mild steel.
