Stainless Steel Sheet Surface Treatment

1. Pickling

Pickling is performed to remove any high-temperature scaling or a result of handling that might have occurred during the annealing process. It is done through immersion in a passivating acid solution. This step also assists in further cleaning and preparation of the metal for the next phases of the production process.

2. Passivation

After pickling, the plates are passivated to remove any free iron and other contaminants left behind. This ensures the stainless steel sheets offer optimum corrosion resistance. Passivation can be achieved through immersion in a nitric acid solution, electrochemical treatment, or a citric acid method, depending on the facility's preferences and environmental regulations.

3. Electro-polishing

In cases where an ultra-smooth, near-mirror finish is required, electro-polishing may be employed. This process uses a combination of electricity and an electrolyte to remove a thin layer of metal, which results in a surface that is not only brilliantly polished but also clean on a microscopic level, enhancing the stainless properties.

FAQ

Q: What are the common grades of stainless steel sheets?

A: There are many grades of stainless steel available. Lork Group offers sheets in the following grades: 304, 304L, 316/316L, 301 Ann, 301QH, 301HH, 301FH, 302, 309, 310, 321, 330, 347, 409, 410, 430, 600, 625, 718. The grades are determined by a chemical formula.

Q: How is the corrosion resistance of stainless steel sheets measured?

A: Stainless steel is normally considered to be resistant to uniform corrosion in a specific environment if the corrosion rate does not exceed 0.1 mm/year. Resistance to uniform corrosion generally increases with increasing levels of chromium, nickel, and molybdenum.

Q: What determines the price of stainless steel sheets?

A: The pricing of stainless steel varies significantly based on its grade and form. Each grade, 304, 316, 303, and 17-4 PH, has unique properties and production costs, while forms like sheets, coils, and bars are influenced by different factors in manufacturing and market demand.

Q: Can stainless steel sheets be used outdoors without rusting?

A: If it is exposed to chloride plus humidity, yes. But you are more likely to see pitting rather than the widespread surface rust that you see on carbon steels. If you have a humid environment free of chloride, stainless steels have good corrosion resistance.

Q: What is the tensile strength of typical stainless steel sheets?

A: The tensile strength of 304 stainless steel is at a minimum of 515 MPa and can typically reach 625 MPa as a maximum. The yield strength of 304 stainless steel is 205 MPa. When the steel is placed under stress at 205 MPa or higher, it will become permanently deformed.
