General Purpose Spring Cold Heading Free-Cutting REED WIRE Scrubbing Ni-Co
What is Stainless steel
Stainless steel is ferric
which contains more than 12% of chromium to keep from stain and rust.
And it is an alloy steel of complex which consists of carbon, nickel, silicon,
and molybdenum according to its own necessity.
Kinds of Stainless steel
Austenite stainless
steel ~
This is an alloy steel of Ferrum-Nickel.
Major one is 18Cr-8Ni which is non-magnetic at normal and high temperature.
Ferrite
stainless steel
~
This
is an alloy steel of Ferrum and Chromium same as martensitic type.
It dosen't make 'R' type in high temperature because it contains 18%
Chromium.
Martensite stainless steel ~ This
is an alloy steel of Ferrum and Chromium containing 13% Chromium.
Various mechanical properties can be obtained with proper heat treatment.
Characteristics of Stainless steel
As our stainless
steel products are remarkably different from those of regular carbon steel,
these are being used for various applications like
ordinary
springs, cold heading, reed, scrubbers, spring washers, and springs for
precision components.
