Stainless Steel
Stainless steel is especially preferred in the interior and exterior surfaces of the Cold Storage panel for hygiene because of its acidic environmental durability and corrosion resistance. It is produced in different qualities. Products should be selected by taking only the mechanical and chemical values into consideration. 316,304 and 430 grade stainless steel values in the following table are stated since they are the most frequently requested products on the market.
| ASTM Standards | 304 Grade | 316 Grade | 430 Grade |
|---|---|---|---|
|
ASTM Standard |
1.4301 | 1.4404 | 1.4016 |
| %0.2 Yield Strength (Mpa) | 200-500 | 210-500 | 210 |
|
Tensile Strength (Mpa) |
500-700 | 510-610 | 430-600 |
| Hardness (HRB) | 130-180 | 160-200 | 150-190 |
| Corrosion Resistance | It has excellent corrosion resistance in dry air in the atmosphere. Good in non-noist, neutral environment. |
Corrosion resistance has been improved. It is easily used in air, industrial atmosphere and in sea water. |
Corrosion resistance is sufficient in alkaline solutions, in chloride free aquerous and in weak organic acidic enviroments |
| In High Temperature | No formation of scale is seen up to 870°C. In oxidizing and moist chloride environments, tensile corrosion cracking may occur. |
No formation of scale is seen up to 1000°C. It can be used up to 300°C. It is used in chemical, petrochemical and food industries. |
No formation of scale is seen up to 800°C |
