en 10028-7 1.4301 stainless steel plate for Pressure Purpose
Leave a message
When it comes to fabricating pressure vessels, heat exchangers, and high‑pressure piping, selecting the right material is critical. EN 10028‑7 Grade 1.4301 stainless steel plate (commonly known as AISI 304) combines reliable corrosion resistance with proven mechanical strength-making it a top choice for pressure‑purpose applications.
What Is EN 10028‑7 Grade 1.4301 steel plate ?
Standard: EN 10028‑7 covers flat products of austenitic stainless steels intended for pressure purposes.
Grade: 1.4301 is the EN designation for AISI 304, featuring ~18 % Cr and ~8 % Ni.
Properties: Non‑magnetic, excellent weldability, and stable performance at temperatures from –196 °C to +300 °C.
Chemical Composition of EN 10028-7 1.4301 Stainless Steel Plate
The chemical makeup of 1.4301 ensures its corrosion resistance and structural integrity. According to EN 10028-7:2016 and EN 10088-1:2014 standards, the key elements are:
| Element | Content Range (%) |
|---|---|
| Carbon (C) | ≤0.07 |
| Chromium (Cr) | 17.5–19.5 |
| Nickel (Ni) | 8.0–10.5 |
| Manganese (Mn) | ≤2.0 |
| Silicon (Si) | ≤1.0 |
| Phosphorus (P) | ≤0.035 |
| Sulfur (S) | ≤0.030 |
Mechanical Properties of EN 10028-7 1.4301 Stainless Steel flat Plate
In its annealed (soft) condition, 1.4301 exhibits the following mechanical characteristics:
| Property | Typical Value | Testing Standard |
|---|---|---|
| Tensile Strength (Rm) | 515–720 MPa | EN ISO 6892-1 |
| Yield Strength (Rp0.2) | ≥205 MPa | EN ISO 6892-1 |
| Elongation at Break (A) | ≥40% | EN ISO 6892-1 |
| Hardness | ≤201 HB / ≤92 HRB | EN ISO 6506-1 (Brinell) |
| Impact Toughness | Excellent at cryogenic temperatures (-196°C) | EN ISO 148-1 |
| Elastic Modulus (E) | 193–200 GPa | Calculated from industry data |
It is worth noting that cold working (e.g. rolling) can increase the tensile strength to 780-820 MPa while reducing the elongation. However, for pressure vessel applications, the annealed condition is preferred to ensure ductility and resistance to stress corrosion cracking.
Applications of EN 10028-7 1.4301 Stainless Steel Plate
Pressure Vessels: Ideal for boilers, heat exchangers, and storage tanks due to its resistance to scaling and pitting in moderate corrosive environments.
Food & Beverage Industry: Used in processing equipment, pipelines, and storage tanks due to its hygienic properties and resistance to organic acids.
Medical Devices: Compliant with ISO 10993 standards for biocompatibility, making it suitable for surgical instruments and implants.
Chemical Processing: Resistant to weak acids (e.g., sulfuric acid <20%) and alkalis, suitable for reactors and pipelines.
