Description
BS En 10219 S355Jr(European Standard) SSAW Pipe is a very popular circular steel hollow section for cold formed welded structures, with a steel grade of S355Jr.S "represents structure," JR "represents impact testing at room temperature of 20 ℃ (minimum impact energy of 27 joules)," H "represents hollow section, and EN 10219 is the European standard for cold-formed welded hollow sections; It is commonly used in buildings, steel structures, pile foundations, bridges, foundation engineering, and general load-bearing pipes. In terms of mechanical performance, when the wall thickness is less than or equal to 16mm, the yield strength should be greater than or equal to 355MPa; When the wall thickness is greater than 16mm and less than 40mm, the yield strength is greater than or equal to 345Mpa; The tensile strength of structural pipes should be greater than or equal to 470Mpa.
Mechanical Properties
| Steel Name | Yield Strength | Tensile Strength (MPa) | Elongation(%) | Impact Toughness | |
| WT≤16mm | 16mm＜WT＜40mm | ||||
| S355jr | ≥355 Mpa | ≥345 Mpa | ≥470 Mpa | ≥22 | 27 joules @ 20 ° C (JR) |
Unique Advantages
You will find that due to the excellent welding performance of EN 10219 S355JR, it will be easier to weld when connecting structures on site. Thanks to its excellent strength, you can see that S355JR has better load-bearing capacity, which allows you to reduce the cross-sectional size and build a lighter structure; Due to the excellent ductility and low-temperature toughness of EN 10219 S355JR, you will find it suitable for molding and bending, and can ensure impact toughness, making your structure more robust and complete.
Chemical Composition
| Element | C | Si | Mn | P | S | N | CE (maximum value) |
| EN 10219 S355JRH (maximum%) | 0.22 | 0.55 | 1.60 | 0.035 | 0.035 | 0.014 | 0.45 |
| You should note that EN 10219 S355JRH has strict limits on the content of carbon, phosphorus, and sulfur, with a carbon equivalent (CEV) limit of 0.45%, both of which ensure good on-site welding performance. | |||||||
How To Choose: Comparison of EN 10219 Hollow Section Grades
| Steel Grade | Yield Strength (Mpa) | Tensile Strength (Mpa) | Impact Temperature | Typical Applications |
| S235JR(H) | 235 | 360 | 20°C | Lightweight structural applications |
| S275JR(H) | 275 | 410 | 20°C | Medium structured applications |
| S355JR(H) | 355 | 470 | 20°C | Heavy duty structural pile foundation |
S355J2(H) | 355 | 470 | -20°C | Low temperature structural pile |
You need to note that for the most demanding structural and pile foundation applications, we recommend using S355JRH or S355J2H grades. | ||||
