On October 25, the flat steel operation area of the rolling mill of PGTG Special Steel Technology Group is in full swing. The high-precision mirror corrosion-resistant alloy steel produced for PetroChina is stepping up production. This batch of corrosion-resistant alloy steel will be the core component of the key project of Guangdong Chemical Industry. The materials used.
PetroChina has been purchasing corrosion-resistant alloy steels with high quality and guaranteed delivery time worldwide. With the advancement of China's special steel technology, PetroChina has gradually turned to China to purchase high-performance corrosion-resistant alloy steel. As a strategic supplier of Sinopec, PGTG participates in the construction of many key projects of China National Petroleum Corporation.
The surface of the high-quality corrosion-resistant alloy required by the project is as smooth and smooth as a mirror, and even small flaws in hair are not allowed to exist.
From materials to precision corrosion-resistant alloy steels to leave the factory, it has to go through more than 30 processes, involving 20 items in the flat steel work area. In order to ensure that each product fully meets the needs of users, we strive to achieve the ultimate in product appearance quality, flatness, dimensional accuracy, and internal quality inspection of flaw detection. At the same time, set up a high-end product stacking area for special management to ensure product quality in all aspects.
It is understood that corrosion-resistant alloy steel has good high temperature resistance, crack resistance, and corrosion resistance, which can effectively solve the corrosion problems of general stainless steel and other metal and non-metal materials in engineering. Due to the complexity of the process, its core manufacturing technology is in the hands of a few foreign companies.
Beginning in 2002, PGTG began to research and develop corrosion-resistant alloy materials. At the beginning of 2010, it had the production capacity of corrosion-resistant alloy steel. It successfully produced a series of high-performance corrosion-resistant alloy steels, which filled the technical gap in the field of corrosion-resistant alloy steel production in China and ended Corrosion-resistant alloy steel can only rely on the history of imports.
