High Temperature Resistant 310S Flange Hexagonal Nut/310s Screw Nut Good Mechanical Properties Industrial Use

Corrosion resistant 310S stainless steel flange hexagonal nut washer screw.

In the industrial field, especially in high-temperature and corrosive environments, material selection is crucial. Austenitic heat-resistant stainless steel 310S, as a high-performance special steel, has become an ideal choice for manufacturing screws due to its excellent high temperature resistance and corrosion resistance. This article will delve into the characteristics and wide application areas of 310S screws, revealing how they maintain stable performance under extreme conditions and become the preferred material for many engineering projects.

Distinctive features and excellent performance

Austenitic heat-resistant stainless steel 310S screws are known for their excellent high-temperature strength and oxidation resistance. In high temperature environments up to 1200 ℃, 310S can still maintain good mechanical properties and is not prone to deformation or failure, mainly due to its high content of chromium (about 25%) and nickel (about 20%). In addition, 310S also contains appropriate amounts of silicon and molybdenum, further enhancing its corrosion resistance in oxidizing atmospheres, allowing it to maintain a smooth surface at high temperatures and prevent the formation of oxide scales.

Corrosion resistant and adaptable to harsh environments

In addition to high temperature performance, 310S screws also exhibit excellent corrosion resistance. In industries such as chemical industry, petroleum refining, and thermal power generation, corrosive media such as strong acids and alkalis are often encountered, which ordinary materials are unable to handle. The 310S screw, due to its high proportion of nickel and chromium in its composition, can form a stable passivation layer in these harsh environments, effectively resist corrosion erosion, extend service life, and reduce maintenance costs.

Widely applicable, with a wide range of fields

Due to its unique performance, austenitic heat-resistant stainless steel 310S screws are widely used in multiple key fields:

Energy industry: In boilers and heat exchangers of thermal power plants, 310S screws are used to secure high-temperature pipelines and equipment, ensuring their safety and reliability during long-term high-temperature operation. In the chemical industry, the corrosion resistance of 310S screws makes them an ideal choice for connecting components in chemical reaction vessels, storage tanks, conveying pipelines, and other devices. They can maintain stability even in environments with strong corrosive chemicals.

The chemical composition of 310S stainless steel mainly includes iron (Fe), nickel (Ni), chromium (Cr), molybdenum (Mo), manganese (Mn), silicon (Si), phosphorus (P) and sulfur (S). ‌‌

310S stainless steel is a high-alloy stainless steel belonging to the 25Cr-20Ni system, with excellent high-temperature oxidation resistance. The specific range of its chemical composition is as follows:

‌Iron (Fe): Remainder, is the main component of 310S stainless steel.

‌Nickel (Ni): 19-22%.
‌Chromium (Cr): 24-26%.
‌Molybdenum (Mo): 0.75%.
‌Manganese (Mn): ≤2.00%.
‌Silicon (Si): ≤1.50%.
‌Phosphorus (P): ≤0.045%.
‌Sulfur (S): ≤0.030%.
‌Carbon (C): ≤0.08%.
These chemical components give 310S stainless steel good oxidation resistance, corrosion resistance, acid and alkali resistance and high temperature resistance. It is widely used in aerospace, chemical, petroleum, electronics, medicine, food processing, machinery manufacturing and other fields, especially in high temperature environment, such as electric heating furnace tube and other occasions, 310S stainless steel performs well.
