Koolstofinhoud
Het koolstofgehalte in EN E295 is beperkt tot maximaal 0,22%, wat bijdraagt aan een betere lasbaarheid en vormbaarheid. Een lager koolstofgehalte zorgt ervoor dat het staal ductiel blijft en gemakkelijk te vormen is, waardoor het ideaal is voor toepassingen die ingewikkelde ontwerpen en vormen vereisen. Dit lage koolstofgehalte vergemakkelijkt bovendien thermische behandelingen, waardoor verschillende mechanische eigenschappen kunnen worden bereikt door processen zoals gloeien of normaliseren.
Manganese and Silicon
Manganese and silicon are present in EN E295 to improve its strength and hardness. Manganese, in particular, enhances the steel’s tensile strength while maintaining good ductility. Silicon acts as a deoxidizing agent, which helps in ensuring a clean and uniform microstructure. This uniformity is crucial for the steel’s performance, particularly in applications involving dynamic loads or cyclic stresses.
Fosfor en zwavel
Phosphorus and sulfur are typically considered impurities, and their content is kept to a minimum to prevent any negative effects on the steel’s properties. High levels of these elements can lead to brittleness and reduced impact resistance, which are undesirable in structural applications. Controlling these impurities is essential for maintaining the steel’s integrity, especially in environments subject to temperature fluctuations or corrosive elements.
Mechanische en fysische eigenschappen
The performance of EN E295 in different applications largely depends on its mechanical and physical properties. These characteristics determine how the material behaves under various conditions and stresses.
| Property | Waarde | Belangrijkheid |
|---|---|---|
| Treksterkte (MPa) | 370-510 | Weerstand tegen breken onder spanning |
| Rekgrens (MPa) | ≥ 295 | Stress at which plastic deformation begins |
| Rekpercentage (%) | 20-25 | Ability to stretch without breaking |
| Hardheid (HBW) | 135-180 | Weerstand tegen indrukking en slijtage |
| Dichtheid (g/cm³) | 7.85 | Mass per unit volume |
Treksterkte en vloeigrens
EN E295 offers a tensile strength ranging from 370 to 510 MPa, providing sufficient resistance to breaking under tension. The yield strength, at a minimum of 295 MPa, indicates the stress at which the steel begins to deform plastically, ensuring that it can support significant loads without permanent deformation. This makes it suitable for load-bearing applications such as beams and girders in construction.
Hardness and Elongation
De hardheid van EN E295 varieert van 135 tot 180 HBW, wat zijn weerstand tegen oppervlakte-indrukking en slijtage weerspiegelt. Het rekpercentage van het materiaal, tussen 20% en 25%, duidt op zijn vermogen om zich uit te rekken of te verlengen voordat het breekt; een essentiële eigenschap voor constructietoepassingen die flexibiliteit vereisen. Deze combinatie van hardheid en rek zorgt ervoor dat EN E295 zowel schurende als trekbelastingen kan weerstaan.
Density and Impact Resistance
With a density of 7.85 g/cm³, EN E295 is comparable to other carbon steels in terms of weight, making it suitable for applications where weight is a critical factor. Its impact resistance is also noteworthy, providing durability and longevity in harsh environments. This resilience is particularly beneficial in infrastructure projects exposed to severe weather or seismic activity.
