The reasonable selection of stainless steel parts or equipment materials requires the following conditions and professional knowledge.

(1) Service conditions

Cold drawn profile steel manufacturers point out that the service conditions of stainless steel parts or equipment, including the composition of corrosive medium, temperature, pressure, stress state and service life, are the prerequisites for the selection of stainless steel. Fully understanding the use of components is the primary condition for the rational selection of stainless steel.

(2) Engineering practice experience

Under similar service conditions, the actual use of stainless steel materials is an important basis for reasonable selection of materials, which should be paid special attention.

(3) In depth understanding of stainless steel properties and related data

Stainless steel materials shall be selected according to the working conditions of components or equipment. The material selector shall have a comprehensive understanding of the properties of various stainless steels, the environmental factors limiting their use and whether they are easy to purchase.

(4) Simulation test data

Due to the lack of practical experience in many corrosive environments, laboratory simulation test data or on-site installation data are often the key to reasonable selection of stainless steel materials.
