Anonymous users2024-02-052507 stainless steel forgings material characteristics:
2507 is a ferritic-austenitic (duplex) stainless steel, which combines the most beneficial properties of many ferritic steels and austenitic steels, and has excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion due to the high content of chromium and molybdenum in this steel. And the mechanical strength is also very high.
Grade: AISI2507
Standard: UNS
Features & Applications:
Chemical Composition: Carbon C: Silicon Si:
Manganese mn:
Phosphorus p: sulfur s:
Chromium CR: 24-26
Nickel ni:molybdenum mo:
Nitrogen n: copper cu:
Hot forging characteristics: 2507 stainless steel forgings hot forging temperature range is limited, when the temperature is too low, the ferrite with poor plasticity will be seriously cracked in the deformation area, when the temperature is too high, the ferrite is too soft and thermal tearing may also occur, so the temperature is very critical in the control when forging 2507 stainless steel forgings, and the forging temperature range is 1200 1025:. The 2507 stainless steel forgings after forging need to be hardened by solid solution water.
Duplex stainless steels are very soft at solution temperatures, and if the forging does not have sufficient support, it will twist and deform, which is very important for large-diameter thin-walled forgings, and the twisted product is more difficult to reshape or straighten than austenite.
2507 stainless steel forgings have high strength compared with austenitic stainless steel, so it is required to increase the power of forming equipment, even then it is necessary to consider the rebound caused by high strength, and leave a certain forming margin during the forming process. Some data also propose to adopt the method of warm forming, reduce the influence of forming rebound, however, it is very difficult to control the heating temperature and heating uniformity of large-size stainless steel forgings, so that there is bound to be a local temperature too high in the heating process, resulting in the precipitation of harmful components between phases, affecting the mechanical properties and corrosion resistance of the material, therefore, it is not recommended to adopt warm forming. After thermoforming, solution treatment and rust removal are required.
Mechanical characteristics: 2507 stainless steel forgings have high compressive strength, impact strength, low coefficient of thermal expansion and high thermal conductivity. These properties are suitable for many structural and mechanical parts, where the impact strength is high and should not be exposed to temperatures above 570°F for long periods of time, which may weaken their toughness.
Tensile strength: b 795MPa, yield strength b 550MPa, elongation: δ 15%, hardness 310 (HB).

Anonymous users2024-02-01<> is made of stainless steel.
It belongs to the ferritic Odan Ling Sitzer stainless steel, which is one of the types of stainless steel, also known as super duplex stainless steel. It combines the performance characteristics of ferritic stainless steel and austenitic stainless steel. The chromium content and molybdenum of this stainless steel are relatively high, so the characteristics of corrosion resistance will be more prominent, and the strength is also good.
Its components include chromium, nickel, molybdenum, etc.

Anonymous users2024-01-312205 is a duplex stainless steel, and the strength is twice that of austenitic stainless steel. 2507 is higher than 2205.
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.

It is normal for Bamberg to have a lot of praise, and it is installed that it has been used for more than two years since the installation, and I have been very satisfied, and there is nothing to find fault with. At the beginning, three masters came to help me install, very careful, covered my other furniture with a dustproof cloth, afraid of dirty, when installing the cabinet, I also explained to me some places that need to be paid attention to, and it is convenient to get started, because this kind of cabinet is not afraid of moisture, I am directly wet rag scrubbing, it doesn't take long every day, especially trouble-free.
