Q:
Under certain conditions, sulfuric acid generally does not corrode stainless steel strips. The performance of stainless steel when exposed to sulfuric acid is influenced by various factors, including the acid's concentration and temperature, the grade of stainless steel, and the duration of exposure. At room temperature, stainless steel is typically resistant to weak sulfuric acid solutions (up to 10%). The natural passive film on the stainless steel surface provides excellent corrosion protection under these circumstances. The specific grade of stainless steel can affect its resistance, with austenitic stainless steel (e.g., 304 and 316) offering better corrosion resistance compared to ferritic or martensitic grades. However, as the concentration or temperature of sulfuric acid increases, the corrosion resistance of stainless steel may diminish. Higher concentrations (above 10%) or elevated temperatures can lead to localized corrosion, such as pitting or crevice corrosion. To combat this, higher alloyed stainless steels, like duplex or super duplex grades, are commonly employed as they offer improved resistance to sulfuric acid. It is crucial to note that prolonged exposure to sulfuric acid can eventually cause corrosion in stainless steel. To minimize the risk, it is advisable to limit the exposure time and acid concentration. Regular maintenance and proper cleaning practices can also help preserve the corrosion resistance of stainless steel in the presence of sulfuric acid.
Q:
Stainless steel strips have the capability to undergo plating or coating with another metal. To achieve this, a layer of a different metal is deposited onto the surface of the stainless steel strip. This process serves multiple purposes, such as enhancing appearance, providing corrosion resistance, improving hardness or lubricity, or enhancing electrical conductivity. Various methods can be employed to accomplish the plating or coating, including electroplating, electroless plating, physical vapor deposition (PVD), or chemical vapor deposition (CVD). Each method has its own advantages and limitations, and the choice depends on the desired properties and application requirements. Considerations must be made regarding the compatibility between the stainless steel and the plating or coating material, the thickness of the layer, and the specific environmental conditions the strips will be exposed to. In summary, plating or coating stainless steel strips with another metal is a common practice in numerous industries to achieve desired functional or decorative properties.
Q:
The specific grade and alloy composition can cause variations in the electrical resistivity of stainless steel strips. In general, stainless steel has a relatively high resistivity compared to other metals. At room temperature, the resistivity of stainless steel strips typically falls within the range of 70 to 72 micro-ohm centimeters (µΩ·cm). This increased resistivity is attributed to the presence of chromium and other alloying elements, which contribute to the corrosion resistance and mechanical properties of stainless steel. It should be noted that factors such as temperature, impurities, and processing conditions can also impact resistivity, leading to varying values in different situations.
