Application of nitrogen-controlled 00Cr17Ni12Mo2 (316NG) steel

Application of 00Cr17Ni12Mo2 (316NG) Controlled Nitrogen Steel

00Cr17Ni12Mo2 (316NG) Controlled Nitrogen Steel is a stainless steel newly developed in China. This steel is based on standard 00Cr17Ni12Mo2 and improves its corrosion resistance. It is usually used in environments containing corrosive media such as chlorides and acidic gases.

00Cr17Ni12Mo2 (316NG) Controlled Nitrogen Steel contains a small amount of nitrogen in its composition. Its nitrogen content is usually between 0.8-1.3%. This addition of nitrogen provides better resistance to localized corrosion such as pitting and crevice corrosion. At the same time, nickel is also an effective alloying element for increasing chemical stability and corrosion resistance. Controlled nitrogen minimizes or prevents the heat affected zone when welding.

The most significant benefit of 00Cr17Ni12Mo2 (316NG) Controlled Nitrogen Steel is that it improves the stability and corrosion resistance of 00Cr17Ni12Mo2. This steel is particularly suitable for applications where chloride and other corrosive elements are present. It can be used in a variety of industries including petrochemical, oil and gas, and food processing.

For example, it is suitable for flanges, valves, and pumps operating at 305-725°F (151-384°C) in aqueous and acid solutions. In the food processing industry, 00Cr17Ni12Mo2 (316NG) Controlled Nitrogen Steel is often used for equipment such as heat exchangers, piping systems, and fermenters. This steel is also suitable for pressure vessels, columns and tanks.

In addition to its excellent corrosion properties, 00Cr17Ni12Mo2 (316NG) Controlled Nitrogen Steel provides excellent formability and weldability. This steel can be cold-formed, hot-formed, machined and welded using standard welding processes. It can also be easily cleaned and is non-toxic and non-magnetic.

00Cr17Ni12Mo2 (316NG) Controlled Nitrogen Steel is also cost-effective. It can be used in place of more expensive alloyed stainless steels, reducing the material expense for applications requiring corrosion resistance. In general, it offers price performance balance and can be an economical choice for many industrial applications.

Overall, 00Cr17Ni12Mo2 (316NG) Controlled Nitrogen Steel is superior in corrosion resistance, which makes it an ideal material for a variety of corrosive applications. It can withstand corrosion in acidic media, such as chlorides and acidic gases, and offers excellent welding and forming capabilities. Its affordability and wide range of applications make it a popular choice among many industrial and commercial applications.

00Cr17Ni12Mo2(316NG) steel, also known as SG-A4 marine grade stainless steel, is an improved version of ordinary 316 steel, with superior performance in terms of corrosion resistance, especially intergranular corrosion resistance. This new stainless steel has been widely used in ships and associated coastal appliances such as tanks and pipelines due to its excellent corrosion resistance under various corrosive environments.

00Cr17Ni12Mo2(316NG) steel is a ferrite-containing austenitic stainless steel. Its general compositions match that of classic AISI 316 steels, similar chemical elements and content but higher nitrogen content than traditional stainless steel. With excellent nitrogen content, the intergranular corrosion resistance of the material is improved at the same time, which makes it have better comprehensive performance than ordinary SUS316 stainless steel.

The 200 series austenitic steel has been widely used in ships, pipes, marine chemical industry and others in recent years due to its excellent intergranular corrosion resistance. Its excellent corrosion resistance is attributed to the high content of nitrogen in the steel and its combination with the conventional chromium-nickel austenitic stainless steel. The micro structure of the steel is an austenite structure, which is composed of a large number of released nitrides and intergranular corrosion reisistance can be greatly improved due to the increase of nitrogen content.

In addition, 00Cr17Ni12Mo2(316NG) steel also has excellent corrosion resistance in sea water, which is the most corrosion-resistant steel among the commonly used austenitic stainless steels, so it can be safely used in highly corrosive environments and become an ideal material for use in chemical pipelines. Therefore, this new stainless steel has been widely used in ships and associated coastal appliances such as tanks and pipelines due to its excellent corrosion resistance under various corrosive environments.
