F51 is a duplex stainless steel with twice the strength of austenitic stainless steel. 2209 welding wire is used.

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.

<> am honored to answer for you, thank you for your patience and wait for you to find out the remaining imitation of the inquiry: F51 can use 625 electrode, the answer is no. F51 is a material grade that usually refers to stainless steel.

The 625 electrode is a nickel-based alloy welding material, which is mainly used for welding alloy materials in high-temperature and corrosive environments. When using welding materials, the appropriate welding materials should be selected according to the actual situation. If F51 material needs to be welded, it is generally recommended to use a welded hollow material similar to it to ensure good performance and corrosion resistance of the weld.

Therefore, when welding F51 material, it is recommended to choose a welding material designed for F51 instead of 625 electrode.

The material of F55 is welded with E(R)2594 electrode. S32760 (F55, Super Duplex Stainless Steel, <>.)

S32760 (F55, is a high-alloy super duplex stainless steel, mainly used in various strong corrosive environments. S32760 duplex steel has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical and subsea equipment. It has strong resistance to chloride corrosion, high thermal conductivity and low coefficient of thermal expansion.

Its high chromium, molybdenum and nitrogen content makes it highly resistant to speckle, crevice and other corrosion. The excellent comprehensive properties of S32760 duplex steel are better than those of general duplex steel, such as 2205, S31803, etc.

S32760 duplex steel can resist a variety of inorganic acids and organic acids, and its added copper elements make it have excellent resistance to non-oxidizing acid corrosion, S32760 is also resistant to strong alkali corrosion, but S32760 duplex steel is not suitable for use in the case of long-term working temperature above 300, because above this temperature, the toughness of the material will be significantly reduced.
