DIN 17100 St52.3 rectangular structural steel pipes were shipped to Australia.
DIN 17100 is standard applied to steel sections, steel bars, wire rods, flat products seamless and welded, square and rectangular hollow sections, forgings, and semi-finished products in the general structural steels which are delivered in the hot formed or normalized condition after production.
St52.3 is one of the grades, and the material number is 1.0570.
Before delivery, Botop arranges for professional quality personnel to carefully inspect the products to ensure that the product quality fully meets customer requirements.
First, the surface quality, width, height, length, squareness, and other appearance dimensions of the structural steel pipe are carefully inspected to ensure compliance with standards and customer requirements.
Next, the chemical and mechanical properties of the structural steel pipe are checked.
EN 17100 St52.3 has the following chemical composition requirements:
| Grade | Chemical composition in % by wt. | ||||||||
| C | P | S | Additional nitrogen combining elements (e.g. at least 0.020 % Al to tal) | ||||||
| for product thickness in mm | |||||||||
| ≤16 | ＞16 ≤30 | ＞30 ≤40 | ＞40 ≤63 | ＞63 ≤100 | ＞100 | ||||
| EN 17100 St52.3 | 0.20 max | 0.20 max | 0.22 max | 0.22 max | 0.22 max | by agreement | 0.040 max | 0.040 max | yes |
The chemical composition of St52.3 is measured by a spectrometer, and all element contents meet customer requirements compared to applicable requirements.
The mechanical properties of EN 17100 St52.3 mainly include tensile strength and yield strength, which are measured by tensile testing.
| Grade | Tensile strength Rm | Upper yield point ReH | |||||||
| for product thickness in mm | for product thickness in mm | ||||||||
| ＜3 | ≥3 ≤100 | ＞100 | ≤16 | ＞16 ≤30 | ＞30 ≤40 | ＞40 ≤63 | ＞63 ≤100 | ＞100 | |
| EN 17100 St52.3 | 510 - 680 MPa | 490 - 630 MPa | by agreement | 355 | 345 | 335 | 325 | 315 | by agreement |
After completing all inspections and ensuring that the quality meets the standard requirements, a Material Test Certificate (MTC) is issued. Subsequently, arrangements are made for shipping and related tasks.
