13CrMo44 round bars steel plate for pressure vessel use

13CrMo44 boiler steel is a high-temperature steel that is commonly used in the production of pressure vessels. 13CrMo44 round bars are a type of alloy steel that is primarily used in applications where high-temperature and pressure are present. The material has excellent mechanical properties and is ideal for use in harsh environments.

The chemical composition of 13CrMo44 round bars includes:

- Carbon (C): 0.10 – 0.18%
- Silicon (Si): 0.10 – 0.35%
- Manganese (Mn): 0.40 – 0.70%
- Phosphorus (P): ≤ 0.025%
- Sulfur (S): ≤ 0.020%
- Chromium (Cr): 0.70 – 1.15%
- Molybdenum (Mo): 0.40 – 0.60%

The addition of chromium and molybdenum allows 13CrMo44 to withstand high temperatures and maintain its structure under extreme pressure. The presence of these elements also makes the material highly resistant to corrosion and oxidation.
