15-5 PH vs 304 Paslanmayan Polad - Fərq nədir?

Paslanmayan poladlar occupy a prominent position in many fields because of their corrosion resistance, durability, and versatility. Among the various paslanmayan polad dərəcəli, 15-5 PH (Precipitation Hardening) and 304 are widely used for diverse applications. While both alloys share some common characteristics, they differ significantly in many aspects. So, 15-5 PH vs 304 paslanmayan polad – what’s the difference? In this article, we aim to provide a detailed comparison between 15-5 PH and 304 stainless steel, highlighting their distinct features and applications.

15-5 PH vs 304 Paslanmayan Polad - Fərq nədir?

15-5 PH vs 304 Stainless Steel – 1. Composition

The fundamental difference between 15-5 PH and 304 stainless steel lies in their composition. 15-5 PH is a precipitation-hardening martensitik paslanmayan polad ehtiva edir xrom, nikel, mis, and aluminum. The addition of copper and aluminum allows for age-hardening treatment, which significantly increases its strength and hardness.

On the other hand, 304 stainless steel, also known as 18-8 stainless steel, is an austenitic stainless steel. It contains 18% chromium and 8% nickel, which gives it its corrosion-resistant properties. 304 stainless steel also contains small amounts of carbon, manganese, silicon, and other elements to enhance its mechanical properties.

15-5 PH vs 304 Stainless Steel – 2. Mechanical Properties

Due to their different compositions, 15-5 PH and 304 stainless steel exhibit distinct mechanical properties. 15-5 PH, after age-hardening treatment, offers high strength and hardness, making it suitable for load-bearing applications. It also exhibits good ductility and toughness, allowing it to be formed and machined into complex shapes. However, its corrosion resistance is slightly inferior to that of austenitic stainless steels like 304.

On the contrary, 304 stainless steel boasts excellent corrosion resistance, making it suitable for applications in harsh environments. It maintains its corrosion resistance even in the presence of chloride ions, which can attack other stainless steel grades. 304 stainless steel also offers good ductility and weldability, but its strength is lower compared to 15-5 PH.

15-5 PH vs 304 Stainless Steel – 3. Applications

The choice between 15-5 PH and 304 stainless steel depends largely on the specific requirements of the application. 15-5 PH, due to its high strength and hardness, is ideal for applications where both corrosion resistance and load-bearing capabilities are crucial. It is commonly used in aerospace components, surgical implants, and high-strength fasteners.

On the other hand, 304 stainless steel, with its excellent corrosion resistance, is widely used in applications where corrosion resistance is the primary concern. It is a popular choice for kitchenware, architectural components, and many other industrial applications where exposure to harsh environments is expected.

Nəticə

In summary, 15-5 PH and 304 stainless steel differ significantly in composition, mechanical properties, and applications. 15-5 PH offers high strength and hardness after age-hardening treatment, making it suitable for load-bearing applications. Its corrosion resistance, though good, is slightly inferior to 304 stainless steel. On the other hand, 304 stainless steel boasts excellent corrosion resistance, making it ideal for applications in harsh environments.
