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.

Q5: Can stainless steel rust?

A5: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Continuous casting is a widely used method that involves pouring molten steel into a water-cooled mold, which then solidifies into a continuous strand or billet. This process offers high production rates, improved quality control, and reduced energy consumption compared to other methods. Continuous casting is ideal for producing large volumes of steel billets with consistent dimensions. Ingot casting, on the other hand, is an older and less commonly used method. It involves pouring molten steel into individual molds called ingot molds, which solidify into solid blocks or ingots. Once solidified, the ingots are then reheated and shaped into billets through processes like rolling or forging. Ingot casting allows for greater flexibility in terms of alloy composition and size, but it typically requires more energy and has a slower production rate compared to continuous casting. Direct chill casting is another popular process, especially for producing aluminum alloys. It involves pouring molten steel into a water-cooled mold, similar to continuous casting. The main difference is that direct chill casting uses a rotating mold to create a cylindrical, or sometimes rectangular, billet. This process offers better control over the solidification process, resulting in improved microstructure and mechanical properties of the billet. Other less common steel billet casting processes include electromagnetic casting, where an electromagnetic field is used to control the flow of molten steel, and centrifugal casting, which involves pouring molten steel into a rotating mold to create cylindrical billets. These methods are typically used for specialized applications and are not as widely adopted as continuous casting or ingot casting. In conclusion, the different types of steel billet casting processes include continuous casting, ingot casting, direct chill casting, electromagnetic casting, and centrifugal casting. Each method offers unique advantages and is suitable for different production requirements and steel grades. The choice of casting process depends on factors such as desired billet size, production volume, alloy composition, and cost considerations.
