Jaypee pliers are manufactured from stainless steel. While stainless steel has superior corrosion resistance, it will discolor if exposed to higher than recommended concentration of certain chemicals like acids.  

Some instruments are made of carbon steel. This steel is much more easier to handle and work with. But these instruments have plated surface of nickel or chrome to increase their corrosion resistance. These instruments are not in demand because they do not keep the modern aseptic principles, due to many drawbacks like peeling of nickel and lack of appearance. Instruments made of this steel are very sensitive to chemicals and temperature than stainless steel. 

Jaypee instruments withstand all sterilization treatments and temperatures up to 200 deg C without losing any of their qualities. They posses smooth surfaces and handles. Beaks have where necessary smooth, rounded flutes. Best workmanship, superior material, modern hygienic design and unlimited durability qualify Jaypee instruments s an absolute top quality product.
