EN P500QL2 EN 10028-6
Boiler and Pressure Vessel Steel Product Introduction
EN P500QL2 EN 10028-6 steel grade offers a lot of advantages over traditional mild steel grades. It is highly resistant to corrosion and abrasion, meaning it can be used in aggressive environments without any additional protective coatings. It is also very resistant to high temperatures and has good thermal stability, making it suitable for elevated temperature applications. Additionally, the strength-to-weight ratio of this steel grade make it an ideal choice when lightweight yet strong components are required.
Our company has steel products billets, steel products, hot-rolled sheets, cold-drawn sheets, seamless steel pipes, steel bars and other products. EN P500QL2 EN 10028-6 has a good reputation in the market, high-quality products, and thoughtful service in the steel industry. EN P500QL2 EN 10028-6 has complete specifications, and the products are widely used in aerospace, petrochemical, and construction projects, with low requirements for products, easy processing and low dimensional accuracy requirements. And provide cutting, bending, welding, drilling, and other processing services.

EN P500QL2 EN 10028-6 Chemical element
EN P500QL2 EN 10028-6 in addition to carbon, steel also contains a small amount of manganese (Mn), silicon (Si), sulfur (S), phosphorus (P), oxygen (O), nitrogen (N) and hydrogen (H). These elements are not intentionally added to improve the quality of steel, but are brought in by ore and smelting process, so they are called impurity elements. These impurities have a certain impact on the properties of steel. In order to ensure the quality of steel, the chemical composition of all kinds of steel is strictly stipulated in technical standards.
The main elements proportion is as below:

EN P500QL2 EN 10028-6 Mechanical properties
Introduction of mechanical properties EN P500QL2 EN 10028-6:
Yield point(σs)When the stress of EN P500QL2 EN 10028-6 or specimen exceeds the elastic limit in tension, even if the stress does not increase, the EN P500QL2 EN 10028-6 or specimen will continue to undergo obvious plastic deformation. This phenomenon is called yielding, and the minimum stress value when yielding occurs is called yield point.
Tensile Strength(σb) : The maximum stress of EN P500QL2 EN 10028-6 during tension from the beginning to the time of fracture. It indicates the ability of EN P500QL2 EN 10028-6 to resist fracture.
Elongation(δs) : The percentage of the plastic elongation length to the original sample length is called elongation.
Yield-strength ratio(σs/σb) : The ratio of yield point (yield strength) to tensile strength of EN P500QL2 EN 10028-6 is called its yield strength ratio. The greater the yield-strength ratio, the higher the reliability of structural parts.
Hardness: Hardness is the ability of EN P500QL2 EN 10028-6 to resist hard objects pressing into its surface. The higher the hardness, the better the wear resistance.
