Custody
①. Pay attention to moisture, dust, oil, lubricating oil, etc. during storage, so as to avoid rust on the surface, or poor welding and corrosion resistance.
②. When water is immersed between the film and the steel plate substrate, the corrosion rate is faster than that without the film.
3. The warehouse should be kept in a clean, dry and ventilated place, and the original packaging state should be maintained. The stainless steel with the film should be protected from direct light. The film should be checked periodically. If the film deteriorates (the life of the film is 6 months), it should be replaced immediately. If the packaging material is soaked when adding pad paper, the pad should be removed immediately to prevent surface corrosion.
●Transportation
In order to avoid surface scratches during transportation, use rubber or sleepers, and use stainless steel as special protection materials as much as possible. In order to avoid surface pollution caused by fingerprints, gloves should be worn during operation. The following table is the introduction of high temperature resistant stainless steel plate with higher unit price
Heat-resistant steels are commonly used in the manufacture of components that work at high temperatures in industrial sectors such as boilers, steam turbines, industrial furnaces, and aviation and petrochemicals.
309S stainless steel plate: (0Cr23Ni13)
Features: It can withstand repeated heating below 980 ℃, and has high high temperature strength, oxidation resistance and carburization resistance.
Uses: Furnace materials.
310S stainless steel plate: (0Cr25Ni20)
Features: suitable for making various furnace components, the maximum temperature is 1200 ℃, and the continuous use temperature is 1150 ℃.
Uses: Furnace materials, automobile purification equipment materials.
253MA:
Features: Avesta Sheffield AB's 253MA is a heat-resistant Austenitic stainless steel for applications requiring high creep strength and good corrosion resistance design. Its operating temperature range is 850~1100 ℃.
Uses: In addition to the alloying elements chromium and nickel, this grade of stainless steel also contains a small amount of rare earth metals (Rare Earth Metals, REM), which significantly improves its oxidation resistance. Nitrogen is added to improve creep properties and make this steel fully austenitic. Despite the relatively low chromium and nickel content, this stainless steel has in many cases the same high-temperature properties as highly alloyed steel alloys and nickel-based alloys.
