HOW TO SELECT A GRADE

Stainless steels are engineered materials with good corrosion resistance, strength and manufacturing specifications. They can easily meet a wide range of design criteria, including loading, service life and low maintenance. Select the appropriate stainless steel grade is weighing four qualities in the following order of importance:

O corrosion resistance to heat, the primary reason for stainless steel specification. The specifier must know the nature of the environment and the degree of corrosion and heat resistance required.
Mechanical properties, particularly strength in the room, high or low temperature. The combination of corrosion resistance and strength is the basis for selection.
Manufacturing operations and how the product will be made (eg, forging, machining, forming, welding, stamping, embossing, four slides of operations).
Total costs, including materials and production costs and considering maintenance savings accumulated product with longevity.
Corrosion, heat resistance and mechanical properties are all affected by the chemical composition of stainless steel. As the steel composition is varied, so that the properties. The main elements of stainless steel alloy include:

Chrome
Passive forms of the film surface for making corrosion resistant stainless steel.
Scales up resistance, tensile strength and wear resistance.
Manganese
Improved hot working characteristics.
Up to 2% has no effect on the strength, ductility and toughness.
Above 2% increases the yield strength and tensile strength (as at 201 degree).
Important as a partial replacement of nickel in 201 degree.
Stabilizes the austenitic structure.
Molybdenum
It increases the yield strength; high temperature resistance and corrosion resistance, especially in the sulphite, sulphate, acetate and acetic acid solutions and in an atmosphere of sea water.
Expands the range of passivity and counteracts tendency to pit.
Nickel
Stabilizes the austenitic structure.
Increases high temperature resistance; ductility, making stainless steel easier to form; and corrosion resistance, especially in industrial and marine atmospheres and the chemical, food and textile processing industries.
Silicon
Scale increases resistance by forming an initial scale close to withstand cyclic temperature changes, also slightly increases the tensile strength and hardness.
Resists high temperature cement.
When 1% or more, improves resistance to strong sulfuric acid, but offers little improvement for dilution and is unfavorable in nitric acid service.
* Note: The ductility decreases as the silicon content increases.

Sulfur – Phosphorus Selenium
Increases machinability.
Decreases ductility and transverse tensile strength.
Titanium – Columbium – tantalum
Prevents intergranular corrosion by stabilizing the carbon, titanium or columbium carbides.
It produces a finer grain size.
Stretcher strains reduces drawing and forming by their addition to type 430.
