EN 10297-1 is a European standard that specifies the technical delivery conditions for seamless circular steel tubes made of non-alloy and alloy steels for mechanical and general engineering purposes. One of the steel grades covered by this standard is 34CrMo4, which is a low-alloy steel known for its excellent strength and toughness properties. This article provides an overview of the material, specification, chemical composition, mechanical properties, and applications of EN 10297-1 34CrMo4 seamless alloy steel pipe.
EN 10297-1 34CrMo4 seamless alloy steel pipe is made from a combination of iron and carbon, with the addition of various alloying elements. The main alloying element in 34CrMo4 is chromium, which enhances the steel's hardenability and corrosion resistance. Other alloying elements such as molybdenum and manganese are also present in smaller quantities to improve the steel's strength and toughness.
EN 10297-1 34CrMo4 seamless alloy steel pipe is manufactured according to specific requirements outlined in the standard. The pipe is produced through a seamless process, ensuring a uniform and consistent product. The outer diameter, wall thickness, and length of the pipe are specified to meet the needs of various engineering applications.
| Element | Chemical Composition (% by weight) |
|---|---|
| Carbon (C) | 0.30 - 0.37 |
| Silicon (Si) | 0.40 max |
| Manganese (Mn) | 0.60 - 0.90 |
| Phosphorus (P) | 0.025 max |
| Sulfur (S) | 0.035 max |
| Chromium (Cr) | 0.90 - 1.20 |
| Molybdenum (Mo) | 0.15 - 0.30 |
| Property | Value |
|---|---|
| Tensile Strength | 980 - 1180 MPa |
| Yield Strength | 785 MPa min |
| Elongation | 12% min |
| Impact Toughness | 34J min at -20°C |
| Hardness (HB) | 229 max |
EN 10297-1 34CrMo4 seamless alloy steel pipe finds extensive use in various general engineering applications. Its high strength, excellent toughness, and good weldability make it suitable for components subjected to high mechanical stress, such as shafts, gears, and cylinders. The pipe's corrosion resistance also makes it suitable for applications in aggressive environments. Additionally, it is commonly used in the manufacturing of machinery, automotive parts, and hydraulic systems.
