Description
|
Turbine blade steel ASTM A565 Grade 616 ( Equivalent to SS422, 1.4935 S42200) is usually produced by AOD / EAF followed by electroslag refining ESR if necessary for Military or Civil use.
Major applications and features for this type of grade
Forms and Shapes availableChemical equipment & pats. Mechanical parts used in the condition of corrosion resistance. Automobile parts, exhaust pipe, Electronics, Turbine motor blade. Bolt and nut, Valve, Pressure vessel. Engine components. High strength and boat propeller shafts. Plastic moulding dies Corrosion resistant Heat resistant quality Polishing performance Heat Treatment Practice Heat treatment is only suitable for specific grades of stainless steel. When heat treating a stainless the hardening temperatures, including rate of heating, cooling and soaking times will vary due to several factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult with the heat treatment provider for whole guidance on heat treatment of stainless steel grades. We are delighted to help to work with you the special heat treatment based on your special requirements.
