First of all, let's look at 2205 stainless steel pipe. 2205 is a typical grade of austenitic chromium-nickel-iron type stainless steel, belonging to the austenitic stainless steel series. It has good mechanical properties and process properties, and has high strength and corrosion resistance at high temperatures.
2205, is a medium-sized duplex steel, 2205 profiles are widely used in a variety of industrial structures, oil and gas engineering and need to resist chloride stress corrosion environment. 2205 alloy steel pipe is mainly used in the manufacture of various boilers, heat exchangers, condensers, seamless steel pipes for pipelines and high pressure gas cylinders with high quality carbon structure steel plate and low alloy high strength steel plate; Its representative material is 0cr25ni20si2c4nb. Secondly, what are the advantages of 2205 stainless steel pipe?
1, good weldability:
Because the hardness and strength near the weld are reduced by the cold working hardening effect, cracks are easy to occur during welding and affect the quality of welds.
2, excellent low temperature toughness:
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 tube 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 specifications:
20g, 20mng, 20rmo steel grades have higher hardenability and less overheating sensitivity, and it is suitable to use graded quenching heat treatment process to ensure the use of parts.
6, high wear resistance and fatigue strength: compared with tungsten carbide has a high hardness;
7, low notch sensitivity and temper brittleness tendency:
The impact energy of 2205 alloy tube at room temperature can reach 35jcm2, and the notch impact value is greater than 28jcm2.
8, high polishing performance and surface gloss:
Good surface finish and high mirror 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.
