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

Q460 is a high-strength low alloy steel. The designation method of Q460: Its steel grade is prefixed with "Q", representing the yield point, i.e. yield strength, of the steel. The following numbers represent the yield point value of 460, which represents 460 megapascals. Megapascals are to the 6th power of 10, and pascals are the unit of pressure. Q460 is a type of steel that undergoes plastic deformation only when the stress strength reaches 460 MPa. This means that when the external force is released, the steel can only maintain the shape of the stress and cannot return to its original shape. This strength is greater than that of ordinary steel. The general quality level symbols are A, B, C, D, and E Q460, which appropriately increase the content of microalloying elements while ensuring low carbon equivalent. Good welding performance requires low carbon equivalent of steel, and the increase of microalloying elements not only increases the strength of the steel, but also increases its carbon equivalent. But fortunately, the increased carbon equivalent is very small, so it will not affect the welding performance of the steel.

Q390 high yield strength steel

High yield steel is an extremely cost effective solution, in the case of steel framed buildings, such a cost reduction and simplification of design is a welcome feature.

High performance steel is an ever evolving technology with increasing demands for higher yield and lower weights. The crane and lifting industry is one such market which is driving this technology forward.

Commom Applications

Bridges, buildings, automotive and truck parts, railroad cars, cargo containers, tote boxes, construction equipment, structural tubing, lighting standards and transmission poles.
