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.

- Q: How does precipitation hardening enhance the strength of special steel?
- The process of precipitation hardening, which is also referred to as age hardening, serves to boost the strength of specific steel alloys through a heat treatment technique. This technique involves a series of steps that lead to the formation of small particles or precipitates within the microstructure of the material. The strength of special steel is mainly determined by the arrangement and interaction of its atoms. Initially, the atoms of the alloy are randomly distributed, resulting in a relatively soft and malleable substance. However, through precipitation hardening, the formation of precipitates during the heat treatment process plays a vital role in strengthening the steel. The process commences by subjecting the steel to a high temperature, referred to as the solution treatment or aging temperature. This elevated temperature allows the atoms to dissolve and form a solid solution. Subsequently, the alloy is rapidly cooled to preserve the supersaturated state of the solution. After the rapid cooling, the steel is exposed to a lower temperature, known as the aging temperature. During this stage, the dissolved atoms start to migrate and cluster together, forming small precipitates within the microstructure of the material. These precipitates act as obstacles to the movement of dislocations, which are the primary carriers of plastic deformation in metals. The presence of these precipitates hampers the movement of dislocations, making it more challenging for them to glide through the crystal lattice. Consequently, the strength of the steel is significantly enhanced. The dislocation obstacles provided by the precipitates increase the resistance to deformation, resulting in improved hardness and strength. Furthermore, the size, distribution, and uniformity of the precipitates play a crucial role in determining the extent of strength enhancement. Smaller and more evenly distributed precipitates offer a higher density of obstacles, leading to a greater strengthening effect. Additionally, the process of precipitation hardening also influences other material properties, such as corrosion resistance and toughness. To conclude, precipitation hardening strengthens special steel by creating small precipitates within its microstructure. These precipitates impede the movement of dislocations, increasing resistance to deformation and resulting in improved hardness and strength. This heat treatment process is pivotal in the development of high-performance special steel alloys utilized in diverse industries.
