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.

Q: What are the different surface treatments for improved fatigue resistance in steel billets?: Some of the different surface treatments that can improve fatigue resistance in steel billets include shot peening, nitriding, and induction hardening. Shot peening involves bombarding the surface of the billets with small steel shots, which creates compressive stresses that help to increase fatigue strength. Nitriding is a process where the steel billets are exposed to nitrogen gas at high temperatures, forming a hard nitride layer on the surface which improves both hardness and fatigue resistance. Induction hardening involves heating the surface of the billets using high-frequency currents and then rapidly quenching it, resulting in a hardened surface layer that enhances fatigue resistance.

Q: What are the different types of steel used for manufacturing billets?: Manufacturing billets commonly employ various types of steel, each possessing unique properties and applications. Some frequently utilized steel types for this purpose encompass: 1. Mild Steel: Widely employed for billet manufacturing, mild steel exhibits low carbon content and is renowned for its strength and ductility. It suits general-purpose applications that do not necessitate high strength. 2. Carbon Steel: Containing higher carbon levels than mild steel, carbon steel offers enhanced hardness and strength. Hence, it is suitable for wear-resistant applications like tools and machinery components. 3.
