Why are surgical instruments made of stainless steel? Which substances are mixed to get stainless steel?
help fast please
Answers
Answer:
A) Stainless steel (sometimes referred to as inox steel) is one of the most commonly used metal alloys in the manufacture of surgical implements.
Austenitic 316 steel is a type of stainless steel used often, and is referred to as “surgical steel”. This is because it is a tough metal that is very resistant to corrosion. It is also used frequently in the chemical industry.
AISI 301 is the most commonly used metal for manufacturing springs which are useful in medical instruments. It gains mechanical strength when cold-worked, but loses corrosion resistance.
Stainless steel can withstand temperatures as high as 400°C, meaning it can be sterilised easily in an autoclave at 180°C. It also has the benefit of being almost as tough and hard-wearing as carbon steel.
B)Nickel and Chromium are used with iron to form stainless steel
Answer:
Surgical instruments are made of stainless steel because it does not corrode/rust easily and is hard and strong.
Stainless steel contains iron chromium and carbon mixed in a specific ratio.
The percentages are Chromium about 11%, Carbon less than 2% and rest is iron
