DIN 17155 HI Pressure Vessel Steel is a carbon steel grade engineered for robust performance in high-pressure and moderate-temperature environments. Although the DIN 17155 standard has been replaced by EN 10028, HI remains a reference point for its reliability in legacy applications. This steel is valued for its balance of strength, weldability, and cost-effectiveness, making it a staple in traditional pressure vessel manufacturing.
HI Boiler and Pressure Vessel Steel is widely utilized in industries requiring robust containment solutions. Key applications include:
DIN 17155 HI is primarily supplied as hot-rolled plates, alongside other grades in the standard such as HII, 17Mn4, and 19Mn6. These grades cater to varying strength and temperature requirements. The typical dimensional range for HI steel includes:
The chemical makeup of DIN 17155 HI is optimized for weldability and toughness.
Element | Composition (%) |
---|---|
Carbon (C) | ≤ 0.20 |
Silicon (Si) | ≤ 0.35 |
Manganese (Mn) | 0.50–1.30 |
Phosphorus (P) | ≤ 0.035 |
Sulfur (S) | ≤ 0.030 |
This composition ensures minimal impurities, enhancing the steel’s suitability for welding and pressure vessel applications.
The mechanical attributes of DIN 17155 HI enable it to perform reliably under stress.
Property | Value |
---|---|
Yield Strength (MPa) | ≥ 235 (for thickness ≤ 16 mm) |
Tensile Strength (MPa) | 360–480 |
Elongation (%) | ≥ 22 |
Impact Toughness | As per standard testing |
These properties ensure HI steel’s resilience in moderate-temperature pressure environments, maintaining safety and performance.
DIN 17155 HI Pressure Vessel Steel has several equivalent grades in modern standards, offering comparable performance for pressure vessel applications. The table below lists key equivalents:
Standard | Equivalent Grade |
---|---|
EN 10028-2 | P235GH |
ASTM | A516 Gr. 55 |
ASME | SA516 Gr. 55 |
BS 1501 | 151 Gr. 400 |
These equivalents provide flexibility for manufacturers seeking alternatives in global markets while maintaining similar performance characteristics.
