As there are many types of stainless steel and many grades included in the standard, there are a large number of widely used non-standard grades in the same fashion, and these grades have different performances. There are a large number of widely used non-standard grades in the same fashion. These grades have different performances, so choose appropriately The applicable stainless steel grades are very difficult. It involves expertise in materials, corrosion, engineering and other disciplines. In addition, engineering experience is an indispensable and important condition for the reasonable selection of stainless steel.
The necessary conditions for a reasonable choice of stainless steel:
Reasonable selection of stainless steel parts or equipment materials should require the following conditions and subject knowledge.
(1) Service conditions
The service conditions of stainless steel parts or equipment include corrosive medium composition, temperature, pressure, stress state, life expectancy, etc.,
is a prerequisite for choosing suitable stainless steel. A full understanding of the use conditions of the components is the primary condition necessary for a reasonable selection of stainless steel.
(2) In-depth understanding of stainless steel properties and related data
Stainless steel materials should be selected according to the working conditions of the components or equipment. The material selector should have a more comprehensive understanding of the performance of various stainless steels, the environmental factors that limit its use, and whether it is easy to purchase, etc., before they can make a targeted selection.
(3) Engineering practical experience
Under similar service conditions, the actual use experience of stainless steel materials is an important basis for reasonable material selection, and special attention should be paid.
(4) Simulation test data
In many corrosive environments, without actual use experience, laboratory simulation test data or field coupon data are often the key data for the reasonable selection of stainless steel materials.
