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.
Q3: Can stainless steel rust?
A3: 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 types of steel round bar heat treatments?
- Steel round bars can undergo several types of heat treatments, each aiming to enhance specific material properties. Common heat treatments include annealing, normalizing, quenching and tempering, and case hardening. 1. Annealing involves heating the steel round bar to a high temperature and gradually cooling it to room temperature. This process relieves internal stresses, improves machinability, and enhances ductility and toughness. 2. Normalizing, similar to annealing, requires heating the steel round bar to a specific temperature. However, instead of slow cooling, the bar is left to cool in air. Normalizing refines the grain structure, improves mechanical properties, and enhances machinability. 3. Quenching and tempering entails heating the steel round bar to a high temperature and rapidly cooling it using a quenching medium like oil or water. This rapid cooling achieves high hardness and strength. Subsequently, the steel is tempered by reheating it to a lower temperature, enhancing toughness and reducing brittleness. 4. Case hardening is employed to increase the surface hardness of the steel round bar while maintaining a tough core. This treatment involves heating the bar in the presence of carbon-rich substances like gas or liquid carburizing agents. It results in a hardened outer layer, known as the case, while the core remains relatively softer and more ductile. These examples demonstrate the various heat treatments applicable to steel round bars. The choice of heat treatment depends on the desired properties and applications of the steel. Consulting with metallurgical experts ensures the selection of the most appropriate treatment for each specific steel round bar.
