Production flow of Stainless Q235/275 Alloyed Mild Steel Flat Bar with High Quality
The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel with a series of distinct iron-zinc alloys. The resulting coated steel can be used in much the same way as uncoated.
A typical hot-dip galvanizing line operates as follows:
Steel is cleaned using a caustic solution. This removes oil/grease, dirt, and paint.
The caustic cleaning solution is rinsed off.
The steel is pickled in an acidic solution to remove mill scale.
The pickling solution is rinsed off.
A flux, often zinc ammonium chloride is applied to the steel to inhibit oxidation of the cleaned surface upon exposure to air. The flux is allowed to dry on the steel and aids in the process of the liquid zinc wetting and adhering to the steel.
The steel is dipped into the molten zinc bath and held there until the temperature of the steel equilibrates with that of the bath.
The steel is cooled in a quench tank to reduce its temperature and inhibit undesirable reactions of the newly formed coating with the atmosphere.

Q4: What makes stainless steel stainless?
A4: 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.
- Q: Are steel flat bars resistant to fire or heat?
- Steel flat bars are highly resistant to fire and heat. Steel is a non-combustible material, which means it does not burn or contribute to the spread of fire.

Some steel grades have better dimensional stability, such as low alloy steels, which can help minimize these effects. 2. Uniform heating and cooling: Ensuring a uniform and controlled heating and cooling process is essential. This can be achieved through the use of proper heating equipment, such as industrial furnaces with well-distributed heat sources. It is important to avoid localized heating or cooling, as this can lead to uneven expansion or contraction, causing warping or distortion. 3. Preheating: Preheating the steel flat bars before heat treatment can help alleviate internal stresses and reduce the risk of warping. This can be done by gradually increasing the temperature to the desired level in a controlled manner. 4. Proper fixturing: The use of appropriate fixtures or jigs during heat treatment can help support the steel flat bars and minimize distortion. Fixtures should be designed to evenly distribute the load and prevent bending or twisting during the heating and cooling process. 5. Slow cooling: Rapid cooling can induce internal stresses, leading to warping or distortion. Therefore, it is recommended to cool the steel flat bars slowly after heat treatment. This can be achieved by placing them in an insulated container or furnace, or by using heat sinks to control the cooling rate. 6. Stress-relieving treatment: After heat treatment, a stress-relieving treatment can be applied to further reduce internal stresses. This involves heating the steel flat bars to a specific temperature and holding it for a certain period of time, followed by a controlled cooling process. Stress-relieving can help restore dimensional stability and minimize warping or distortion. By following these preventive measures, it is possible to minimize the warping or distortion of steel flat bars during heat treatment, ensuring that the desired properties are achieved while maintaining dimensional integrity.
