11Positive and negative deviation categories of MnNi5-3

Category N deviation: The positive deviation and the negative deviation are equal

Class A deviation: Negative deviation is determined by nominal thickness

Category B deviation: Fixed negative deviation of 0.3

Class C deviation: fixed negative deviation is 0 positive deviation determined by nominal thickness

The national standard project of "nickel-containing steel plate for cryogenic pressure vessels" was approved and formulated by the National Standards Committee. According to the arrangement of the National Steel Standardization Technical Committee SAC/TC183 Steel Standard Committee [2008] No. 01 "Notice on Issuing the National Steel Standard Committee 2008 National Standard Formulation and Revision Plan Project" (No. 165 Plan No. 20074165-Q-605), Anshan Iron and Steel Co., Ltd. and other units are responsible for formulating the mandatory national standard of "Nickel-containing Steel Plate for Cryogenic Pressure Vessel".

Nickel-containing steel plate for low-temperature pressure capacity plate is a very technical level and difficult to produce in China's civil steel, and its production and development need to use advanced equipment conditions and technical routes in the production process of metallurgical enterprises, including high-purity smelting, high-alloy continuous casting, controlled rolling and advanced heat treatment organization control technology. Therefore, the formulation of national standards, non-equivalent use of foreign advanced standards (European standards and national classification society specifications), the introduction of national basic standards, the inclusion of cryogenic pressure vessels with nickel-containing steel plate series of steel grades, so that this standard can meet the design and construction requirements of LNG ships, and can promote the production of China's cryogenic pressure vessel with nickel-containing steel plate physical quality to steadily improve and reach the international advanced level, but also to promote the technological progress of enterprises, for Chinese enterprises to join the international market competition to create more favorable conditions, the standard level to reach the level.
