1. Features
JISG3444 STK290 steel pipe/tube has the following characteristics. In terms of chemical composition, the content of carbon, silicon, manganese, phosphorus, sulfur and other elements are strictly defined, such as phosphorus and sulfur content are not more than 0.050%, which ensures the basic performance and quality stability of the steel. From the manufacturing process, it can be manufactured by seamless, resistance welding, butt welding, automatic arc welding and other ways, the diversity of production processes to meet the needs of different users. In terms of dimensional accuracy, there are clear standards for dimensional tolerances such as outer diameter and wall thickness, for example, when the outer diameter is less than 50mm, the tolerance can be controlled at ±0.5mm, which makes JISG3444 STK290 steel pipe/tube better matched with other components during installation and use. In terms of mechanical properties, the yield strength is not less than 290MPa, and the tensile strength is also standardized, which provides a certain degree of strength and toughness to meet the requirements of general structural stress.

2. Advantages
Compared with other similar products, JISG3444 STK290 steel pipe/tube has obvious advantages. Firstly, it is produced according to strict production standards and has high quality reliability. Produced in accordance with JISG3444 standards, it is subjected to strict inspection processes, which can ensure the consistency and stability of product quality and reduce the risks in the process of use. Secondly, the pipe has a good balance of strength and toughness, which can withstand certain pressure and load, but also has a certain impact resistance, applicable to a variety of complex working conditions. In addition, its specifications are diverse, according to different application scenarios and needs, you can choose the appropriate size of the outer diameter, wall thickness and length, which improves the utilization rate of the material and reduces the cost.

3. Scope of application
JISG3444 STK290 steel pipe/tube has a wide range of applications. In the field of construction, it is commonly used to erect pillars for buildings, such as eaves pillars and exterior columns, and can also be used to make steel pipe piles. In civil engineering, it can be used to build steel towers, scaffolding and other structures to provide support and guarantee for engineering construction. In addition, in some general structural projects, such as small building structures, temporary facilities, etc., JISG3444 STK290 steel pipe/tube is also widely used because of its good performance and economy.
