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.

This is just the name of the alloy material of stainless steel, how do you know which national standard it is without content?

The most important alloying elements for duplex steels are Cr, Ni, Mo, and N. Among them, Cr and Mo are to increase the ferrite content, while Ni and N are austenite stabilizing elements. Some steel grades also have elements such as MN, Cu, and W.

Cr, Ni, and Mo can improve corrosion resistance. In chloride-containing environments, its resistance to pitting and crevice corrosion is particularly good.

What is the difference between 22cr duplex stainless steel and 2205 duplex stainless steel?

2205 duplex stainless steel is a duplex stainless steel composed of 22% chromium, 3% molybdenum, and 5-6% nickel-nitrogen alloy. It has high strength, good impact toughness, and good overall and local corrosion resistance. Compared to 316 liters and 317 liters of austenitic stainless steel, 2205 duplex stainless steel plate has better resistance to corrosion spots and cracks.

It has a high resistance to corrosion. Compared to austenite, alloy 2205 has a lower coefficient of thermal expansion and a higher thermal conductivity. Compared to austenitic stainless steel, 2205 duplex stainless steel plate has twice the compressive strength.

Compared to 316 liters and 317 liters, designers can reduce weight and costs.

2507 is a ferritic-austenitic (duplex) stainless steel that combines the most beneficial properties of many ferritic and austenitic steels, and has excellent resistance to pitting, crevice and uniform corrosion due to the high content of both chromium and molybdenum. The bidirectional microstructure guarantees a high resistance to stress corrosion cracking and a high mechanical strength.

Dear, I am glad to answer for you: the difference between 2205 duplex stainless steel pipe and 304 stainless steel pipe is in **A; The differences between 2205 duplex stainless steel pipe and 304 stainless steel pipe are as follows; (1) The yield strength is more than twice that of ordinary austenitic stainless steel, and it has sufficient plastic toughness required for molding. The wall thickness of a tank or pressure vessel made of duplex stainless steel is 30-50% less than that of commonly used austenite, which helps to reduce costs.

2) It has excellent resistance to stress corrosion cracking, even duplex stainless steel with alloy content has a higher resistance to stress corrosion cracking than austenitic stainless steel, especially in the environment containing chloride ions. Stress corrosion is a prominent problem that is difficult to solve in ordinary austenitic stainless steel. (3) The corrosion resistance of 2205 duplex stainless steel, which is the most commonly used in many media, is better than that of ordinary 316L austenitic stainless steel, while super duplex stainless steel has extremely high corrosion resistance, and some media, such as acetic acid, formic acid, etc., can even replace high-alloy austenitic stainless steel, and even corrosion-resistant alloys.

4) It has good local corrosion resistance, and its wear corrosion resistance and fatigue corrosion resistance are better than austenitic stainless steels compared with austenitic stainless steels with comparable alloy content. (5) The linear expansion coefficient of austenitic stainless steel is lower than that of carbon steel, which is close to carbon steel, suitable for connection with carbon steel, and has important engineering significance, such as the production of composite plates or linings. (6) Regardless of the dynamic load or static load conditions, it has a higher energy absorption capacity than austenitic stainless steel, which has obvious advantages for structural parts to cope with sudden accidents such as collision, **, etc., and has practical application value.
