**1. What material is P355N?**
P355N is a normalized weldable fine-grain steel specified in the European standard EN 10028-3. It is used for pressure vessels and structural components, offering good weldability and toughness. The "N" indicates it has undergone normalization heat treatment.
**2. What is P355GH equivalent to ASTM material?**
P355GH (EN 10028-2) is closely equivalent to **ASTM SA-516 Grade 70** in terms of chemical composition and mechanical properties. Both are used for pressure vessels in moderate to high-temperature service. Confirm exact equivalence via direct specification comparisons.
**3. What is the thickness of P235GH?**
Thickness is not intrinsic to the material but depends on manufacturing standards (e.g., EN 10028-2). P235GH plates/sheets are typically available in thicknesses ranging from **8 mm to 100+ mm**, subject to application requirements and standard allowances.
**4. What is P265GH material?**
P265GH is a non-alloy steel for pressure vessels, defined by EN 10028-2. It is designed for elevated temperature service (up to ~525°C) and has moderate strength, with a minimum yield strength of 265 MPa. It is weldable and used in boilers, heat exchangers, and storage tanks.
**5. What is the material code for P235GH?**
The EN 10028-2 standard designates it as **"P235GH"** (no separate numeric code). In some systems, it may align with **UNS K02401** or national standards, but "P235GH" is the primary identifier in European contexts.
