309S STAINLESS STEEL COIL309S is a free cutting stainless steel containing sulfur, which is
used in occasions where free cutting and high surface finish are
mainly required. It can withstand repeated heating below 980 ℃, and
has high high temperature strength, oxidation resistance and
carburization resistance.
Stainless steel coil
Stainless Steel (Stainless Steel) according to GB/T20878-2007
definition is rust, corrosion resistance as the main
characteristics, and chromium content is at least 10.5%, carbon
content is not more than 1.2%
The invention and use of stainless steel coil dates back to eralier
stage in history. develop high-strength wear-resisting alloy steel,
specializing in solving the problem of the bore wear. Brearley and
his assistants collected various types of steel produced at home
and abroad, various properties of alloy steel, in a variety of
different properties of machinery performance tests, and then
select the more suitable stainless steel coils. One day, they
tested an alloy steel containing a lot of chromium. After the wear
test, they found that the alloy was not wear-resistant. So they
recorded the results of the experiment and threw them into a
corner. Experimental results show that it is not afraid of acid,
alkali, salt stainless steel. The stainless steel coil was invented
by a German mullah in 1912, but the mullah had no idea what it was
for. Brearley invented stainless steel in 1916 obtained the British
patent and began to mass production, so far, the stainless steel
coil accidentally found in the garbage became popular all over the
world, Henry Brearley is also known as the "father of stainless
steel".
Our company is a professional stainless steel coil manufacturer
