FAQ：
Q1: How soon can we receive the product after purchase?
A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.
Q2: What makes stainless steel stainless?
A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

RF Plasma Nitriding: RF (Radio Frequency) plasma nitriding is a similar process to DC plasma nitriding, but instead of using a direct current, a radio frequency power supply is used to generate the plasma. This method allows for better control of the nitriding process and can be used for more complex geometries. 3. Pulse Plasma Nitriding: In this method, short pulses of high voltage are applied to the steel surface, creating a plasma discharge. The pulses are repeated at regular intervals, allowing for precise control over the nitriding process. This method is often used for steels with sensitive properties that can be affected by prolonged exposure to high temperatures. 4. Plasma Assisted Nitriding: This method combines plasma nitriding with other surface treatment techniques, such as physical vapor deposition (PVD) or chemical vapor deposition (CVD). The steel is first coated with a thin layer of a reactive material, and then nitrided in a plasma atmosphere. This combination of techniques can enhance the surface properties of the special steel, such as wear resistance or corrosion resistance. 5. Glow Discharge Nitriding: This method involves placing the special steel in a chamber filled with a nitrogen-rich gas, such as ammonia. A high voltage is applied to create a glow discharge, which ionizes the gas and generates nitrogen ions that diffuse into the surface of the steel. This method is commonly used for small parts or components with complex shapes. It is important to note that the selection of the most appropriate method for surface ion nitriding of special steel depends on factors such as the desired properties, the geometry of the steel, and the specific requirements of the application.
