AISI 321 steel is a high-alloy chromium-nickel steel with an austenitic structure, increased heat resistance and heat
resistance. The use of steel 321 is permissible at temperatures of 600-800℃, while products made of steel 321 remain
in their original state for a long time.
It has no obvious magnetic properties, is unstable to oxidation and is not subjected to hardening.
The price of steel 321 is high due to the addition of titanium to the composition

Characteristics and properties of stainless steel strip coil:
corrosion resistance - extends the life of the stainless steel tape;
resistance to moisture, acids, oils and other substances, contact with which is often possible in production and during
the use of parts;
endurance to hostile environment and adverse weather conditions;
relatively low specific gravity;
good flexibility even at low temperatures;
heat resistance;
simple and convenient processing (easy to cut, pull, stamp, bend);
Stainless strip coil is characterized by high electrical and thermal conductivity, resistant to many aggressive environments,
easy to weld, non-toxic. stainless steel strip service life can be about 30 - 50 years.
Stainless steel strip is produced by cold or hot rolling on mills. The resulting rolls are cut into strips of a given width and
wound into rolls for further packaging. Depending on the production method, hot-rolled stainless steel strips and cold-rolled
stainless steel strips are distinguished. often used: AISI 301,AISI 304, AISI 321, AISI 316Ti, AISI 309S, AISI 310S,
AISI 430,AISI 904L,Duplex 2205.
Application of stainless steel strip:
in mechanical engineering, oil and aircraft industries;
in the production of brackets, springs and brackets;
in chemical, food, paper production.
