For manufacturing of surgical and dental instruments, LIFECARE first chooses the correct stainless steel grade for required instruments. LIFECARE takes the help of ASTM & DIN standards, DIN book, ISO's standard manual and other suitable literature for the manufacturing of surgical instruments.
For surgical instruments, mostly two types of stainless steels are used:-
AUSTINITIC STAINLESS STEEL (AISI 300 Series) Non-Magnet.
MARTENSITIC STAINLESS STEEL (AISI 400 Series) Magnet.
Mostly Martensitic stainless steel is used with AISI 410 & AISI 420 grades for the manufacturing of General Surgical Instruments.
Austenitic and Martensitic stainless steel are used for the manufacturing of Dental instruments.
AISI 410 Grade is used for manufacturing of NON-CUTTING Instruments.
AISI 420 Grade is used for the manufacturing of CUTTING Instruments.
AISI 304 is used for the manufacturing of the Tips of Scalars and Elevator Handles.
Other Stainless steel Grades are also used according to requirement of the instruments.
