Three Major Causes of Oxidation in Stainless Steel

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 strictly in accordance with the product model and product characteristics, not only makes the product quality greatly compromised. For example, when the content of chromium element of ASTM A312 304 Pipe is insufficient, it not only affects the corrosion resistance and formability of the product, When used in chemical, equipment, and production industries, there are potential product quality and safety hazards; at the same time, it also affects the appearance and oxidation resistance of the product.

Austenitic Stainless Steel Pipe

3. Human Reasons: This is one of the most common causes of product oxidation in some consumers when using stainless steel products. Some consumers are not operating properly in product use and maintenance. In particular, some stainless steel tube products used in the food chemical equipment industry have a high probability of causing artificial oxidation. For the artificial oxidation of steel products, it is necessary to have the correct knowledge of product use and regular and effective maintenance and maintenance, so as to reduce the oxidation caused by improper use of humans.

Baosteel Special Metals Co., Ltd., formerly known as Shanghai No. 5 Steel Plant, was founded in September 1958 and was awarded the honorary title of State-level Enterprise and National Quality Management Award. It is known as the leader of China's special steel industry. In November 1998, Shanggang No. 5 Plant was integrated into Baosteel Group and changed its name to Baosteel Group Shanghai Wugang Co., Ltd. In May 2005, the company's core assets were acquired by Baoshan Iron & Steel Co., Ltd., and the group was established as a special steel branch of Baosteel Co., Ltd. In June 2018, in accordance with the new round of strategic planning of "One Base and Five Yuans", China Baowu Group further promoted the development of "one place and two industries" of special steel land, and established Baowu Special Metallurgical Co., Ltd. (referred to as Baowu Special Metallurgy Co., Ltd.) ), Baowu Special Metallurgy will strive to become "the leader of th

What are the Benefits of Using Stainless Steel Pipes in Pipeline Installation?

图片
As a  Seamless Stainless Steel Tubing Supplier , share with you. Steel resistant to corrosion by weakly corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt is called stainless steel. Stainless steel pipe is a hollow, long, round steel. It is widely used in various industrial transportation pipes and Mechanical structure parts, etc. Here are some of the benefits of using  China Welded Stainless Steel Tubing  for pipeline engineering installation. Duplex Stainless Steel Pipe 1. The stainless steel tube can not only play a good supporting role, but also can transmit liquid materials and gaseous materials over long distances to improve the efficiency of industrial production and make people's lives more convenient and comfortable. High, suitable for the construction of infrastructure in many fields, so it is very common in life. 2. The stainless steel pipe has a hollow section, so it is suitable for liquid, gas and sol

Duplex Stainless Steel Pipe safety restrictions and requirements

图片
Duplex stainless steel pipe safety restrictions and requirements: 1. It is necessary to control the comparative example. The most suitable ratio is that the ferrite phase and the austenite phase are each half, and the number of one phase cannot exceed 65% at most, so as to ensure the best comprehensive performance. If the two ratios are out of tune, such as too many ferrite phases, it is easy to form a single-phase ferrite in the welded HAZ, which is sensitive to stress corrosion cracking in some media. Duplex Stainless Steel Pipe 2. It is necessary to master the organization transformation law of  Duplex Stainless Steel Pipe  and familiarize with the TTT and CCT transition curves of each steel grade. This is the key to correctly guide the process of heat treatment and thermoforming of duplex stainless steel. The precipitation of the brittle phase of duplex stainless steel should be More sensitive than austenitic stainless steel. 3. The continuous use temperature of the dupl
