The advantages of  Duplex Stainless Steel Pipe  compared to ferritic stainless steel are as follows: (1) The comprehensive mechanical properties are better than ferritic stainless steel, especially plastic toughness, and are not as sensitive to brittleness as ferritic stainless steel. (2) In addition to stress corrosion resistance, another local corrosion resistance is superior to ferritic stainless steel. (3) Cold working process performance and cold forming performance are much better than ferritic stainless steel. (4) The welding performance is also much better than that of ferritic stainless steel. Generally, no preheating is required before welding, and no heat treatment is required after welding. (5) The application range is wider than that of ferritic stainless steel. Compared with ferritic stainless steel, the disadvantage of duplex stainless steel is as follows: The alloying element content is high, the price is relatively high, and the general ferrite does no

As a  Nickel Alloy Pipe Factory , let's talk about the reasons why stainless steel often oxidizes. 1. Production process reasons: This is one of the causes of oxidation of steel products. From the perspective of the production process and product characteristics, forming a thin oxide film on the surface of the product is the basic process to avoid oxidation and steel products. One of the main features that distinguish it from other steel products. However, when the production process is insufficient or inadvertent, the oxide film in the air is incomplete and discontinuous, and the oxygen in the air directly undergoes a redox reaction with some elements in the product, thereby causing the product to exhibit oxidation. 2. Reasons for the proportion of products: Some manufacturers reduce the proportion of important elements such as chromium and nickel to reduce the production cost, and increase the content of other factors such as carbon. This production phenomenon, which is not

As a  Tube Nickel 200 Factory , let's share some of the basics of stainless steel classification. First, let's first understand what is stainless steel. Popularly speaking, steel that does not rust is called stainless steel. However, it is academically resistant to corrosion of corrosive media such as air, steam, water, and chemically etched media such as acids, alkalis, and salts. Also known as stainless acid-resistant steel. In practical applications, steel that is resistant to weak corrosive media is often referred to as stainless steel, while steel that is resistant to chemical media is referred to as acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter generally has rust. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Chromium is the basic element for obtaining corrosion resistance of stainless steel.
