17-7PH Stainless Steel Characteristics:
17-7PH austenite - martensite precipitated hardening stainless steel, which is developed based on 18-8CrNi, is also known as control phase transition stainless steel.
17-7PH stainless steel after solid solution treatment for unstable austenitic organization, has the good plastic toughness and processability, after adjustment,
after making the carbide precipitation austenitic composition change, again through martensitic transformation processing, most organizations into toughness good low-carbon tempered martensite,
the state for the use of steel, has a good medium temperature mechanical properties.17-7PH corrosion resistance is better than normal martensitic stainless steel.
