Carbon steel and stainless steel have the same basic composition of
iron and carbon. Their main difference is that the alloy contains
carbon steel, low alloy content is 10.5%, and chromium content must
be greater than or equal to 10.5% of stainless steel, its essence
is to make carbon steel and stainless steel with unique physical
properties of the difference. Carbon steel and stainless steel are
different, but that doesn't mean either one is stronger. It's all
about the use of the environment. Each material has advantages and
disadvantages, and the key is to help match the target steel.
(1) advantages and disadvantages of carbon steel
Advantages :1, low price, easy smelting; 2, good processing
technology; 3, improve performance (C %, heat treatment)
Disadvantages :1, poor hardenability; 2, the intensity level is
low, the performance is low; 3, poor temper stability, poor heat
resistance; 4, low temperature resistance, carbon steel at
embrittlement temperature toughness becomes brittle; 5, no
corrosion resistance, carbon steel can not resist atmospheric,
acid, alkali and salt corrosion; 6, low magnetic conductivity, low
carbon steel; 7, non-magnetic, carbon steel in the magnetic field
will inevitably be magnetized.
2) advantages and disadvantages of stainless steel
The main advantages of stainless steel are: corrosion resistance or
high temperature resistance, acid resistance medium, high
temperature resistance, high temperature oxidation (heat does not
peel off) of stainless steel.
Disadvantages of stainless steel: the main cost is high, more
expensive; In addition, stainless steel corrosion is not alkaline
medium.
