Since many types of stainless steel, included in the standard grades and more, while there are a lot of non-standard grades are widely used, which grades the performance of different, but there are a lot of non-standard grades widely used, these grades different properties, so aptly choose Suitable grades of difficulty great. It involves expertise in materials science, corrosion science and engineering and other disciplines, in addition, engineering experience is an important condition for the rational use of stainless steel indispensable.
Reasonable choice of stainless steel prerequisite
Reasonable choice of stainless steel parts or equipment shall be necessary materials the following conditions and subject knowledge.
(1) service conditions
Conditions of service stainless steel parts or equipment including corrosion medium composition, temperature, pressure, force status, life expectancy, etc.,
Selecting prerequisites apply stainless steel. To fully understand the conditions of use components, it is a reasonable choice of stainless steel necessary prerequisite.
(2) In-depth understanding of stainless steel performance and related data
Stainless steel materials should be selected according to the working conditions of components or equipment, material selection who deal with all kinds of stainless steel performance, limiting its use of environmental factors, if readily available and so have a more comprehensive understanding of knowledge, it can only be targeted for selection.
(3) engineering practices
Service under similar conditions, stainless steel is an important basis for practical experience in the use of reasonable selection, should pay special attention.
(4) simulation test data
In many corrosive environments, in the absence of practical experience in the use condition, laboratory simulation test data or field data coupon critical data is often a reasonable choice of stainless steel materials.
