Custody
①. Pay attention to moisture, dust, oil, lubricating oil, etc. during storage to avoid rust on the surface, or deterioration of corrosion resistance due to poor welding.
② When moisture is immersed between the film and the steel substrate, the corrosion rate will be faster than when there is no film.
③. Store in a clean, dry and ventilated place. Keep the original packaging. The stainless steel film should be protected from direct light. The film should be checked periodically. If the film deteriorates (film life: 6 months), it should be replaced immediately. If the packing material is soaked when adding paper, the pad should be removed immediately in order to prevent surface corrosion.
transportation
In order to avoid surface scratches during transportation, use rubber or sleepers, and use special stainless steel protection materials as much as possible. In order to avoid surface pollution caused by fingerprints, gloves should be worn during operation. The following is the introduction of high temperature resistant Stainless Steel Sheets with higher unit price
Heat-resistant steel is often used in the manufacture of boilers, steam turbines, industrial furnaces, aviation, petrochemical and other industrial sectors that work at high temperatures.
309S Stainless Steel Sheets: (0Cr23Ni13)
Characteristics: It can withstand repeated heating below 980 ℃, and has high high temperature strength, oxidation resistance and carburization resistance.
Use: Furnace materials.
310S Stainless Steel Sheets: (0Cr25Ni20)
Characteristics: suitable for making various furnace components, the highest temperature is 1200 ℃, and the continuous use temperature is 1150 ℃.
Uses: Furnace materials, materials for automobile purification devices.
253MA:
Features: Avesta Sheffield AB's 253MA is a heat-resistant austenitic stainless steel, designed for applications that require high creep strength and good corrosion resistance. design. Its operating temperature range is 850~1100 ℃.
Application: 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 completely austenitic. Although the content of chromium and nickel is relatively low, this stainless steel has the same high temperature characteristics as highly alloyed alloy steels and nickel-based alloys in many cases.
