EN 10219 S355K2H PIPE

EN 10219 S355K2H PIPE

EN 10219 S355K2H steel pipe is a structural steel hollow section that conforms to the European Standard EN 10219. These pipes are commonly used in construction and engineering projects, such as buildings, bridges, and other structures requiring high strength and durability. Pipes are produced using either a cold forming or welding process.

The EN 10219 S355K2H structural hollow pipes undergo multiple product tests. This includes mechanical tests (tensile, impact) and non-destructive testing (ultrasonic, radiographic) to verify quality. We customize the specifications as per the requirements of the clients. Here we offer 24/7 technical support and competitive factory prices.

The material specification of S355K2H is as follows:

  • Grade: S355K2H is a specific grade within the EN 10219 standard.
  • S stands for structural steel.
  • 355 refers to the minimum yield strength (in MPa) of the steel.
  • K2 indicates the steel’s impact energy requirement at -20°C, ensuring good toughness at low temperatures.
  • H denotes that the product is a hollow section.
    EN 10219 S355J0H pipe is a reliable choice. Its excellent mechanical properties, toughness and adherence to strict quality standards make it the ideal material for construction, engineering and infrastructure projects.
    EN 10219 S355K2H steel pipe is a versatile, high-strength structural material widely used in construction and engineering projects. It is characterized by high yield strength, good low temperature toughness and weldability, making it the material of choice for demanding structural applications.

More Information About EN 10219 S355K2H Steel Grade

  • The number of this European Standard (EN 10219 specification)
  • The capital letter S for structural steel
  • The indication of the minimum specified yield strength for thickness ≤16mm is expressed in N/mm2
  • The capital letters JR for the qualities with specified impact properties at room temperature
  • The capital letter J and a number 0 or 2 for the qualities with specified impact properties at 0℃ and -20℃ respectively
  • The capital letter H indicates hollow sections

In addition to the provisions of EN 10219 10.2 for hollow profiles in bundles, each S355J0H profile shall be marked by a suitable and durable method, e.g. painted, embossed, labeled, or additionally labeled as follows:

  • Name of the steel, e.g. EN 10219-S355JOH;
  • Manufacturer’s name or trademark;
  • In the case of a specific check: an identification number, e.g. an order number, allows to associate a product or a delivery unit with a relevant document;
  • Marking of the external inspection representative (if applicable).

When items are supplied in bundles, the EN10219 10.1 marking shall be located on a label securely fastened to the bundle.

The European Standard allows the use of weldable steels only.EN 1011-1 and EN 1011-2 define the key parameters for the welding of products covered by this European Standard. The main concern when welding these materials is the development of cold cracking in the weld zone as the thickness, strength level and CEV of the product increases. Cold cracking can occur for a variety of reasons:

  • Increased concentration of diffuse hydrogen in the weld metal;
  • Structural embrittlement in the heat affected zone;
  • High concentration of tensile stress in welded joints
