Selection for the stainless steel products.
The main factors needed bto be considered at selection of the steel grades include:corrosion resistance,mechanical and physical properties,process performance,costs.
Corrosion resistance: the stainless steel to be selected is mainly used for solving various corrosion problems arose in the actual projects,so the stainless steel corrosion resistance in the corrosive environment is the first factor to be considered by the material selection person.
Mechanial and physixal properties: Mechanical properties inculudes strength,hardness,plasticity, toughness,fatigue etc...and physical properties including expansion coefficient,conductivity factor and magnetic conductiblity.
Process performance: After having been received the steel materials wil be subject to various machining process,such as forming,welding,etc....
Costs: Not only the costs,but also the maintenance cost after putting the equipment into operation and subsequent possible production loss cost, i.e. life cycle costing are to be considered.
