Chemical Composition: C Mn Si P s Cr NiShanghai Xiangqia metal team, looking forward to your consultation!

Duplex stainless steel composed of 21% chromium, molybdenum and nickel-nitrogen alloys. It has high strength, good impact toughness, and good overall and local resistance to stress corrosion. Duplex stainless steels have twice the yield strength of austenitic stainless steels, a feature that allows designers to reduce weight when designing products, giving this alloy an advantage over 316,317L.

This alloy is particularly suitable for temperatures ranging from -50°F to +600°F. This alloy can also be considered for applications beyond this temperature range, but there are some limitations, especially when applied to welded structures.

Duplex stainless steel has twice the compressive strength compared to austenitic stainless steel, and designers can reduce its weight compared to 316L and 317L. Alloy 2205 is particularly suitable for the -50°F +600°F temperature range and can also be used at lower temperatures in tightly restricted situations, especially for welded structures.

Applications:

Pressure vessels, high-pressure storage tanks, high-pressure pipes, heat exchangers (chemical processing industry).

Oil and gas pipelines, heat exchanger fittings.

Sewage treatment system.

Pulp and paper industry sorters, bleaching equipment, storage and handling systems.

Rotary shafts, press rolls, blades, impellers, etc. in high-strength and corrosion-resistant environments.

Cargo boxes for ships or trucks.

Food processing equipment.

1. Keep a short arc and maintain a maximum interlayer temperature of 200.

2. It is recommended to have a slender bead weld to remove the welding slag between the welding layers.

3. Oblique cut thick-walled cross-section to form a V-shaped groove of 75 degrees. Preheating is generally not recommended.

No. 20 steel can use ordinary electrodes, such as E4303 electrodes, E4316 electrodes, E4315 electrodes and so on. Among them, Shiji E4303 electrode is an acid electrode, and welding with this kind of electrode has the advantages of convenient construction and beautiful finished product. E4316 electrode is an alkaline electrode, and welding with this type of electrode is not scattered, and it is easy to have problems such as weld cracking.

When we select the welding vertical return strip, the strength grade of the welding rod should be able to meet the mechanical properties of the base metal, and the working conditions during welding should also be considered.

Hello dear! 2205 and 2209 electrodes are two different welding consumables that are mainly used to weld materials such as stainless steel and corrosion-resistant alloys. Their differences are mainly reflected in the following aspects:

1.Chemical composition: 2205 electrode is a duplex stainless steel electrode, its chemical composition includes elements such as 22% chromium, 5% nickel, 3% molybdenum and nitrogen; The 2209 electrode is a nickel-based alloy electrode, and its chemical composition includes elements such as 22% chromium, 13% nickel, 3% molybdenum and nitrogen.

2.Welding performance: Due to the different chemical composition, the welding performance of 2205 and 2209 electrodes is also different.

2205 electrode has good corrosion resistance and strength, and is suitable for welding duplex stainless steel and other corrosion-resistant alloy materials; The 2209 welding slag strip has a higher nickel content, which can provide better corrosion resistance and high temperature performance, and is suitable for welding superalloys and other corrosion-resistant alloy materials. 3.Applications:

Due to the different chemical composition and welding properties, the application range of 2205 and 2209 electrodes is also different. 2205 electrode is suitable for welding duplex stainless steel, seawater equipment, chemical equipment, etc.; The 2209 electrode is suitable for welding superalloys, aerospace equipment, marine engineering, etc. In short, although 2205 and 2209 electrodes are both welding materials used for welding stainless steel and corrosion-resistant alloy materials, they are different in terms of chemical composition, welding performance and application range, and it is necessary to select the appropriate welding materials according to specific welding needs.

102 is a titanium-calcium coated stainless steel electrode。This 102 electrode adopts foreign advanced technology, the electrode coating is red, has good mechanical properties and metal corrosion resistance to the weld metal, and the arc is soft, the spatter is small, and the electrode is not easy to turn red. 2. What are the functions of the welding rod 1. Improve the stability of arc combustion.

The coated electrode is not prone to arcing and does not burn stably even if ignited. 2. In the process of welding loss, the oxygen and nitrogen in the air will adversely affect the weld, reduce the mechanical properties of the weld, lead to cracks, produce a large amount of gas to cover the arc and the weld pool, and reduce the interaction between the molten metal and the air. 3. Ensure that although the deoxidation of the weld has a protective effect during the welding process, it is inevitable that a small amount of oxygen will enter the molten pool, resulting in the oxidation of metal elements and reducing the quality of the weld.

Therefore, in welding, a reducing agent needs to be added to reduce the oxides that have entered the molten pool. 4. Supplement the weld with alloying elements. Welding rods can add alloying elements to the weld to ensure the mechanical properties of the weld, but some alloy steels need to penetrate through the sock seam of the weld to make the metal close to the base metal composition.

5. Improve welding productivity Welding rod can improve welding productivity, and at the same time, it can also reduce the metal loss caused by spatter and improve the deposition coefficient, so as to improve the yield of welded raw car.
