ALLOY STEEL SEAMLESS TUBES TO DIN EN10216-2 GR. 16MO3
**Product Introduction: Alloy Steel Seamless Tubes to DIN EN10216-2 GR. 16Mo3**
### Product Overview
16Mo3 alloy steel seamless tubes are a type of chromium-molybdenum (Cr-Mo) alloy steel, conforming to the European standard DIN EN10216-2. This standard specifies the technical delivery conditions for non-alloy and alloy steel seamless tubes used in high-temperature applications. This material is widely used in various industries such as petrochemicals, power, and automotive due to its excellent high-temperature performance and good mechanical properties.
### Chemical Composition
- Carbon (C): 0.12-0.20%
- Silicon (Si): ≤0.35%
- Manganese (Mn): 0.40-0.70%
- Phosphorus (P): Maximum 0.025%
- Sulfur (S): Maximum 0.02%
### Mechanical Properties
- Minimum tensile strength: 450 MPa
- Yield strength: At least 280 MPa
- Elongation: At least 22%
### Size Specifications
- Outside diameter (OD): 10.2-711 mm
- Wall thickness (WT): 1.6-100 mm
- Length: 5.8 meters, 6 meters, 11.8 meters or customized as required
### Heat Treatment
16Mo3 seamless tubes are typically subjected to heat treatment processes such as normalizing, quenching, and tempering to achieve the required mechanical and high-temperature properties. For example, the normalizing temperature is 890 to 950 degrees Celsius, followed by cooling in air.
### Application Fields
16Mo3 alloy steel seamless tubes are mainly used in high-temperature service applications, such as petroleum refining pipelines, steam pipelines, and power plant projects. In addition, they are also suitable for the automotive, construction, and oil and gas industries.
### Packaging and Delivery
- Packaging method: Usually bundled (hexagonal), wooden cases, steel/wooden pallets or customized as required.
- Delivery condition: Cold-rolled/hard (BK), cold-rolled/soft (BKW), cold-rolled and stress-relieved annealed (BKS), annealed (GBK), normalized (NBK), etc.
- Delivery time: 7-15 days after payment.
### Quality and Inspection
Before leaving the factory, the products will undergo strict chemical composition inspection, mechanical property testing (including tensile strength, yield strength, elongation, flaring, flattening, bending, hardness, impact testing, etc.), surface and dimensional inspection, non-destructive testing, and hydrostatic testing to ensure they meet relevant standards and user requirements.
### Environmental Protection and Sustainability
16Mo3 alloy steel seamless tubes are 100% recyclable, with the advantages of being environmentally friendly, energy-saving, and resource-conserving. They comply with the national sustainable development strategy and policy support.
