DIN 2445-1 is a standard that specifies the requirements for hot finished seamless steel tubes used in fluid dynamics systems. These tubes are essential in various applications due to their strength, durability, and resistance to pressure. This article will cover the material specifications, chemical composition, mechanical properties, and applications of ST30, ST35, ST45, and ST52 seamless steel tubes.
The seamless tubes covered under DIN 2445-1 are produced from carbon steel and are designed to withstand high pressure and temperature conditions. The standard outlines the dimensions, tolerances, and manufacturing processes to ensure the quality and performance of the tubes.
The following table presents the typical chemical composition of the materials used in the production of ST30, ST35, ST45, and ST52 seamless steel tubes.
Grade | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Silicon (Si) |
---|---|---|---|---|---|
ST30 | 0.12 - 0.20 | 0.30 - 0.60 | ≤ 0.035 | ≤ 0.035 | ≤ 0.40 |
ST35 | 0.15 - 0.25 | 0.30 - 0.70 | ≤ 0.035 | ≤ 0.035 | ≤ 0.40 |
ST45 | 0.20 - 0.30 | 0.40 - 0.70 | ≤ 0.035 | ≤ 0.035 | ≤ 0.40 |
ST52 | 0.22 - 0.30 | 1.20 - 1.60 | ≤ 0.025 | ≤ 0.025 | ≤ 0.40 |
The mechanical properties of the seamless tubes are crucial for their performance in fluid dynamics systems. The following table summarizes the key mechanical properties for ST30, ST35, ST45, and ST52 grades.
Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Hardness (HB) |
---|---|---|---|---|
ST30 | ≥ 235 | 360 - 510 | ≥ 24 | ≤ 160 |
ST35 | ≥ 275 | 410 - 550 | ≥ 22 | ≤ 170 |
ST45 | ≥ 355 | 490 - 630 | ≥ 20 | ≤ 190 |
ST52 | ≥ 450 | 600 - 800 | ≥ 18 | ≤ 210 |
