First, let's take a look at 2205 stainless steel pipe. 2205 is a typical grade of austenitic Inconel-ferrite stainless heat-resistant steel and belongs to the austenitic stainless steel series. It has good mechanical properties and process performance, and has high strength and corrosion resistance at high temperatures.
2205 is a medium-sized dual-phase steel. 2205 profiles are widely used in various industrial structures, oil and gas projects, and environments that require resistance to chloride stress corrosion. 2205 alloy steel pipe is mainly used to manufacture high-quality carbon structural steel plates and low-alloy high-strength steel plates for various boilers, heat exchangers, condensers, seamless steel pipes for pipelines, and high-pressure gas cylinders; its representative material is 0cr25ni20si2c4nb.
What are the advantages of 2205 stainless steel pipe?
1. Good weldability:
Since the cold work hardening effect reduces the hardness and strength near the weld, cracks are prone to occur during welding and affect the quality of the weldment;
2. Excellent low temperature toughness:
It has good plasticity and low temperature impact toughness in the temperature range of -196°C~800°C;
3. Good corrosion resistance:
The chromium content of 2205 alloy pipe reaches about 10.5%, so it also has good corrosion resistance;
4. Excellent mechanical properties:
The yield strength of 2205 alloy pipe is about 980mpa, and the tensile strength is about 1180mpa.
5. Good heat treatment practices:
20g, 20mng, and 20rmo steel types have high hardenability and low overheat sensitivity, so it is suitable to use graded quenching heat treatment process to ensure the use requirements of the parts.
6. High wear resistance and fatigue strength: higher hardness than tungsten carbide;
7. Low notch sensitivity and temper brittleness tendency:
The room temperature impact energy of 2205 alloy tube can reach 35jcm2, and the notch impact value is greater than 28jcm2;
8. High polishing performance and surface gloss:
A good surface finish and high specular reflectivity can be obtained by polishing.
9. Excellent welding performance:
2205 alloy steel pipe can be cut and welded by argon arc welding or plasma arc welding.
