What does J2 n mean?
S355 J2 N is the common high strength steel that is mainly used for construction work. It is a non-alloy structural steel with EN 10025 specification. There are various products manufactured using this steel and steel plates are one of the popular product used in several industries and applications.
How do you read steel standards?
Carbon steel Carbon steels and alloy steels are designated a four digit number, whereby the first digit indicates the main alloying element(s), the second digit indicates tg (top grade) element(s), and the last two digits indicate the amount of carbon, in hundredths of a percent (basis points) by weight.
What are the grades of steel structure?
Yield Strength
| Structural Steel Grade at 16mm | Minimum Yield Strength at nominal thickness 16mm | |
|---|---|---|
| psi | N/mm2 (MPa) | |
| S235 | 33 000 | 235 N/mm2 |
| S275 | 36 000 | 275 N/mm2 |
| S355 | 50 000 | 355 N/mm2 |
What does J2 mean in steel?
J2 and JR refer to the material’s sub-grade – its fracture toughness – which is measured in joules [J] of a material’s toughness at a particular temperature. J2 is a material with a minimum of 27 joules at -20C while JR is a material with a minimum of 27 Joules at +20C (room temperature).
What does N mean in steel?
Normalised or normalised rolled
These include: M – Thermomechanically rolled. N – Normalised or normalised rolled – P355NL1. Q – Quenched and tempered.
How do you identify steel?
You can identify steel by several properties, like its weight, color, and magnetism. Carbon steel, which is commonly used in pipes and buildings, is a dark brown color, while stainless steel is silver and shiny. Check your metal for a number code printed on it, which may indicate that it’s steel.
