| Advantages | Hot rolling can greatly reduce energy consumption and costs. The
metal plastic deformation is high during hot rolling, and the
deformation resistance is low, which reduces the energy consumption
of metal deformation. Hot rolling can improve the processing
performance of metals and alloys. |

Difference between duplex 2205 stainless steel plate and Austenitic
304 stainless steel plate:
1) The yield strength is more than twice as high as that of
ordinary austenitic stainless steel, and has the advantages of
forming
Sufficient plastic toughness. The wall thickness of storage tank or
pressure vessel made of duplex stainless steel is 30-50% less than
that of common austenite, which is conducive to reducing the cost.
2) It has excellent stress corrosion cracking resistance. Even the
duplex stainless steel with the lowest alloy content has higher
stress corrosion cracking resistance than austenitic stainless
steel, especially in the environment containing chloride ions.
Stress corrosion is a prominent problem that ordinary austenitic
stainless steel is difficult to solve.
3) The corrosion resistance of 2205 duplex stainless steel, which
is widely used in many media, is better than that of ordinary 316L
austenitic stainless steel, while super duplex stainless steel has
very high corrosion resistance. In some media, such as acetic acid
and formic acid, it can even replace high alloy austenitic
stainless steel and even corrosion-resistant alloy.
4) It has good local corrosion resistance. Compared with austenitic
stainless steel with the same alloy content, its wear-resistant
corrosion and fatigue corrosion properties are better than
austenitic stainless steel.
5) The linear expansion coefficient of austenitic stainless steel
is lower than that of austenitic stainless steel, close to that of
carbon steel, suitable for connection with carbon steel, and has
important engineering significance, such as the production of
composite plate or lining.
6) No matter under dynamic load or static load, it has higher
energy absorption capacity than austenitic stainless steel, which
has obvious advantages and practical application value for
structural parts to deal with sudden accidents such as collision
and explosion.
