This specification covers hot and cold finsihed bards of stainless and heat resisting steel, including rounds, squares and hexagons and hot rolled or extruded shpaes such a angles, tees and channels for use in boiler and pressure vessel construction. It is also related to the ASME Boiler and Pressure Vessel Code SA- 279 Section II.
ASTM A 484 :
"Standard Specification for general requirements for stainless and heat resisting bards, billets and forgings."
This specification covers general requirements which shall apply to stainless and heat-resisting wrought steel bars, shapes forgings and billets or other semi-finished material (except wire) for forging. Pertinent details contained in this specification are tolerances for size, width, thickness, length and straigthness of bars materials.
CONDITIONS AND SURFACE FINISHES :
Stainless and Heat resisting bars are produced in various conditions and surface finsihed. It is important that the condition be associated with the appropriate finish because each finish is not applicable to every condition.
Corrosion resistance stainless steels :
Because of their superior anti-corrosion properties under all kinds
