SS490 Mechanical Properties

SS490 is a structural hot rolled steel defined by JIS G 3101 standard. It is commonly utilized for diverse structural applications. SS490 has superior tensile strength compared to SS400 steel. It is employed in thicknesses ranging from 6 mm to 120 mm. Its chemical makeup includes a maximum of 0.050 percent of both Phosphorous and Sulphur, with iron and minor impurities. Its mechanical properties make it ideal for manufacturing structural tubes, pipes, rods, and various sectional steels.

SS490 steel Product Introduction

Mechanical properties of this structural steel play a crucial role in its broad application spectrum, with tensile strength and yield point being among the most vital characteristics. When compared with other steel grades, SS490 exhibits superior tensile strength, a metric that impacts structural design significantly. The tensile strength optimization of SS490 is achieved through careful control of alloying elements, with the influence of heat treatment further enhancing this.

The yield point of SS490, another critical mechanical property, is influenced by the alloying elements present, and is also subject to improvement under the right heat treatment conditions. Compared to other steel grades, the yield point of SS490 steel is at the higher end of the scale, thus enabling the design of robust and durable structural components.
