Galvanized Square Pipe EN10219 S355J2H China manufacturer
Introduction s355 square tube
When it comes to construction and manufacturing projects, the quality and durability of materials play a crucial role. Galvanized square pipes and S355J2H steel pipes have become go-to choices due to their strength and versatility. In this guide, we will explore the role of galvanized square pipe manufacturers, the benefits of S355J2H steel pipes, how to find square tube steel suppliers near you, the different sizes available, pricing factors, advantages of galvanized square pipes, applications of S355J2H steel pipes, important factors to consider when selecting square tube suppliers, and tips for proper installation and maintenance. Let's dive in!
Firstly, the chemical composition of S355J2H has been carefully designed, which contains an appropriate amount of elements such as carbon, silicon, manganese, sulfur, phosphorus, etc., ensuring its excellent mechanical properties. Its carbon content ranges from 0.22 to 0.24, belonging to low-carbon steel, which can ensure a relatively balanced strength and toughness of alloy steel, while also having good cold deformation performance and weldability.
EN10219 S355J2H Chemical Composition
Carbon ≤ 0.22%, silicon ≤ 0.55%, manganese ≤ 1.60%, phosphorus ≤ 0.030%, sulfur ≤ 0.030%, nitrogen ≤ not required
Secondly, the mechanical properties of S355J2H are excellent, with a minimum yield point of 355MPa, a minimum tensile strength of 510-680MPa, a minimum elongation of 22%, and a maximum shrinkage of 30% after speckle. These mechanical performance parameters are relatively high, indicating that this low alloy structural steel can withstand large mechanical loads, and has good toughness in bending, impact, and other situations. It can also resist stress corrosion cracking in high or low temperature environments.
EN10219 S355J2H Mechanical Properties
3mm<wall thickness ≤ 16mm: yield strength ≥ 355MPa, tensile strength≥ 470-630MPa, elongation ≥ 20%
3mm<wall thickness  ≤ 16mm: yield strength ≥ 355MPa, tensile strength≥ 470-630MPa, elongation ≥ 20%
