CD4MCUN which country material grade it is

CD4MCUN is an American grade and belongs to duplex stainless steel. N element is added to the base of CD4MCU, and the Ni and Mo content are increased to improve the stainless steel and corrosion resistance of the material.

CD4MCU alloy material: duplex stainless steel.

Introduction: Full name of the grade: 0Cr26Ni5Mo2Cu3

The alloy CD-4MCU is nominally a 26Cr-6Ni alloy (C) with the addition of molybdenum and copper. There is no corresponding deformed steel grade for this alloy. The alloy CD-4MCU is duplex in the as-cast state and is composed of austenite.

Distributed in ferrites.

matrix. Although carbide precipitation is limited by the minimum carbon content of the alloy, it is not necessary to use solution treatment.

Elimination, it will also diffuse in the ferrite matrix, thereby reducing the corrosion resistance, CD-4MCU solution treatment temperature is 1120, keep warm for at least two hours to ensure uniform temperature, slow cooling to 1010 1065, keep warm for half an hour, and then quench. Heat preservation at lower temperatures is to avoid cracking of castings, especially those with thicker sections, during quenching. The heat-treated tissue is also biphasic with 35-40% austenite in a ferrite matrix.

The alloy CD-4MCU is basically ferritic and its yield strength.

It is about twice as much as 19Cr-9Ni austenitic alloy and has high hardness, good tensile plasticity and satisfactory impact toughness.

The high strength and hardness of the alloy combined with excellent corrosion resistance make it particularly suitable for use under corrosive operating conditions, including abrasion and erosion. Alloy CD-4MCU has better corrosion resistance than CF alloy in many corrosive media, and is widely used in oxidation and reduction under strong acid working conditions, and has special resistance to stress corrosion cracking in chlorine environment.

After solution treatment, the CD-4MCU alloy can be further strengthened by precipitation hardening through aging in 480 510. The degree of aging reaction, as well as all the properties of the alloy in the aging state, and the rest including corrosion resistance, strength, impact toughness and quenching cracking tendency are related to the complex phase treatment method, that is, the level of solution treatment temperature, aging temperature and aging time. Because the alloy has sufficient strength and excellent corrosion resistance in many applications after solution treatment, it is not often used in the aging state.

<>CD4MCU is made of duplex stainless steel in China, which is a high-temperature resistant alloy. The carbon content of this material is relatively low, the hardness is relatively high, and it also has good castability and machinability, and the welding performance is also good. Moreover, its corrosion resistance and wear resistance are better than austenitic stainless steels, and the yield strength is also twice that of austenitic stainless steels.

Therefore, it can also be used normally under some conditions with high requirements for corrosion resistance and wear resistance or in strong acid environments. For example, the sewage treatment industry, the filtration and washing industry, etc.

Dear, hello, I am glad to answer for you what is the material of CD45 Answer""CD45 is a high-quality carbon steel material. Carbon steel is an iron-carbon alloy with a carbon content. It is also called carbon steel.

Generally, it also contains small amounts of silicon, manganese, sulfur and phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the plasticity is lower. According to the use, the carbon shed steel can be divided into three categories: carbon envy loss structural steel, carbon tool steel and easy-cut chain loss structural steel, and carbon structural steel is divided into two types: engineering construction steel and machine manufacturing structural steel.

Characteristics: high strength, abrasion resistance, abrasion resistance.

Duplex stainless steel replaces austenitic stainless steel in many fields due to its excellent corrosion resistance, high strength and easy processing and manufacturing.

The market outlook is very broad.

CD4MCU is used to manufacture duplex steel.

It should all be about the foundry industry.

CDA954 does not have a corresponding domestic grade.

C95400 aluminium bronze is the most common alloy in the cast aluminium bronze family. In many heavy-duty applications, it is recommended for high-load, high-wear applications that require tensile strength, good ductility, weldability, or superior resistance to fatigue and deformation in the event of overload. In addition to good anti-friction properties, the metal exhibits low fouling rates under atmospheric conditions, resistance to seawater corrosion, low oxidation rates at higher temperatures, and low reactivity with combustion exhaust by-products.
