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
