Welcome to Tianjin TISCO，Steel expert by your side.
Q460 steel is a low-alloy high-strength structural steel. The nominal yield strength of Q460 steel is 460 MPa. The yield strength of Q460 steel is enhanced by inclusion of alloys, such as niobium and chromium, and thermal mechanical rolling.
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 Steel Introduction
Q460 steel is a Chinese steel grade of Low Alloy High Strength Structural Steel, Yield Strength is 460 MPa, data is tested with 16mm diameter steel bars or steel plates, tensile strength is 550-720 Mpa, test with steel bar Ø≤40mm.For Q460 steel equivalent, chemical composition and mechanical properties, please see the tables below.
Properties and Applications
Q460 steel has much higher strength and has high comprehensive mechanical properties in normalizing, normalizing plus tempering, or quenching plus tempering, all of which are deoxidized with aluminum. It is used for large-scale engineering structures and lightweight structures that require high strength and large loads.
