Jiangsu Jiuming S32101 Stainless Steel Plate, S32101 Stainless Steel Plate Price, Full Specifications
32101 is a nickel-saving duplex steel. Duplex stainless steel refers to a type of stainless steel where the ferrite phase and austenite phase each occupy about half of the solid solution structure, with the content of the less abundant phase generally needing to reach 30%. With a lower carbon content, the chromium content is typically between 18% and 28%, while the nickel content is between 3% and 10%. Some steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N. This type of steel combines the characteristics of both austenitic and ferritic stainless steels, offering higher plasticity and toughness compared to ferrite, no room temperature brittleness, and significantly improved intergranular corrosion resistance and weldability. It also retains the 475°C brittleness of ferritic stainless steel and high thermal conductivity, as well as superplasticity. Compared to austenitic stainless steel, it has higher strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel boasts excellent pitting resistance and is also a nickel-saving stainless steel. S32101

S32101Material Description
LDX 2101It is a low-nickel alloy dual-phase steel with a balanced chemical composition of chromium, molybdenum, and nitrogen content, offering excellent resistance to localized and uniform corrosion. The dual-phase microstructure contributes to high strength and resistance to stress corrosion cracking. Dual-phase steel boasts good weldability. However, there is a risk of embrittlement.LDX 2101Should not be above250°CUsed at temperatures. High-strength alloy with stable pricing.
S32101 General Properties
S32101 is a dual-phase (austenitic-ferritic) stainless steel with relatively low alloy element content. It boasts high mechanical strength, comparable to other dual-phase stainless steels. Its excellent corrosion resistance is on par with most standard stainless steel grades. Combined, these characteristics can be utilized to optimize designs for strength, maintenance, durability, and long-term cost efficiency.

S32101 Corrosion Resistance
Good general corrosion resistance
Suitable for various general applications and environments.
S32101 Pitting and Crevice Corrosion
With the increase in the content of chromium, molybdenum, and nitrogen in the steel, the resistance to pitting and crevice corrosion improves.
These materials exhibit excellent corrosion resistance due to their high chrome and nitrogen content, primarily in chlorinated environments.
S32101 Atmospheric Corrosion
Closely associated with resistance to general corrosion and localized corrosion (such as pitting and crevice corrosion).
Sufficiently durable in most environments.
S32101 Stress Corrosion Cracking
Like all duplex stainless steels, S32101 exhibits excellent resistance to chloride-induced stress corrosion cracking (SCC).
S32101 Heat Treatment
Sheets, plates, and coils are typically delivered under heat treatment conditions. If additional heat treatment is required after further processing, it is recommended to use the following methods.
S32101 Solution Annealing
1020 - 1080°C (1865 - 1975°F), rapidly cooled in air or water.
S32101 manufactured
S32101 Hot Forming
Hot forming is conducted within a temperature range of 1100-900°C (2010-1650°F), followed by solution heat treatment. However, it should be noted that lower strength is observed at high temperatures.
S32101 Cold Formed
Due to the high proof strength of the duplex material, a greater working force is usually required for cold forming than that needed for austenitic steel.
S32101 is suitable for forming operations used in the manufacture of most stainless steels.
Due to its higher mechanical strength and lower ductility, deep drawing, stretching forming, and spinning operations are more difficult to perform than with austenitic steel.
High tensile strength may result in relatively high resilience.
S32101 Welding
S32101 boasts excellent weldability, allowing it to be焊接 using the same processes as other duplex steels.
Generally, the recommendations for welding dual-phase steel also apply to S32101; however, due to the lower alloy content and higher nitrogen content, the arc energy restrictions are not as stringent as those for traditional dual-phase steel.
The appropriate welding method is manual metal arc welding with covered electrodes or gas-shielded arc welding. The welding should be performed within a heat input range of 0.2-2.5 kJ/mm. Preheating or post-weld heat treatment is usually not required.
