With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilised by Titanium (321) or Niobium (347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850 C.
321/S32100/SUS 321 Stainless Steel. Alloy 321 (UNS S32100) is titanium stabilized austenitic stainless steel plate with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 - 1500F (427 - 816C).
Stainless Steel grade AISI 321 Grade 321 is a stabilized austenitic stainless steel similar to Type 304 but with a titanium addition of at least five times the carbon content. This titanium addition reduces or prevents carbide precipitation during welding and in 800 1500 F (427 816 C) service.
GENERAL PROPERTIES Type 321 is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500 F (427 to 816 C).
Alloy 321 exhibits good general corrosion resistance that is comparable to 304. It was developed for use in the chromium carbide precipitation range of 18001500F (427816C) where un-stabilized alloys such as 304 are subject to intergranular attack. The alloy can be used in most diluted organic acids at moderate
321 displays good oxidation resistance in continuous service up to 930 o C, and in intermittent service up to 870 o C.It can also be used within the carbide precipitation range 430 o C - 870 o C without the risk of intergranular corrosion. Mechanical properties are reduced as temperature increases.

321 stainless steel (1.4541) has excellent corrosion resistance at normal temperatures but is primarily designed to perform at elevated temperatures.
Good Answer: 316L is a low carbon SS 321 is similar to 304 with the addition of titanium as a stabilizer. This addition gives it greater inter granular corrosion resistance. Here is a link for thebest sus 321 specification
ASTM specifications list the grade as UNS S30430, and alternative designations for the same grade include "XM-7", "304Cu" and "304HQ". The standard specification for stainless steel fasteners, ISO 3506, includes 302HQ as an acceptable composition for fastener grade A2; it is commonly produced in strength grades A2-70 and A2-80.
ApplicationsAlloy 316/316L (UNS S31600/ S31603) is a chromium-nickel- molybdenum austenitic stainless steel developed to provide improved corrosion resistance to Alloy 304/304L in moderately corrosive environments. It is often utilized in process streams containing chlorides or halides.
Type 321 is a chromium-nickel stainless steel and with the addition of titanium, type 321 is resistant to intergranular corrosion. Type 321's general corrosion is less than Type 302.
Stainless steel wire mesh (AISI 304, 321) made from 0.16-2.0mm stainless steel wire, with mesh size 0.16mm - 12mm.
303 - Free machining for use in automatic machining operations. High corrosion resistant. 304 - The most widely used of the stainless steels. Offers good corrosion resistance to many environments.

Type 321 and 347 tubing intended for use in the manufactured exhaust-stacks, manifolds, blast tubes, ring collectors and similar applications where a weldable corrosion and heat resisting steel is required or for use at 8000 - 1500?F.
321 Better resistance to temperatures of around 600-900C is needed321 has higher hot strength. 3CR12 A lower cost is required, and the reduced corrosion resistance and resulting discolouration are acceptable. 430 A lower cost is required, and the reduced corrosion resistance and fabrication characteristics are acceptable.
The Advantages of Using 321 SS vs. 304/304L SS. Note: To print, please click here. At first glance, it appears that type 304/304L SS is very similar to type 321 SS. When comparing the chemical composition of 321 SS and 304/304L SS, it is clear that the chromium (Cr) and nickel (Ni) ranges of these alloys are very similar.
The austenitic stainless steels are heat treated to remove the effects of cold forming or to dissolve precipitated chromium carbides. The surest heat treatment to accomplish both requirements is the solution anneal which is conducted in the 1850F to 2050F range (1010C to C).
321 321H Stainless Steel is a titanium-stabilised version of 304, used in particular applications within the sensitizing temperature range. Its resistance to sensitization, coupled with its higher strength at high temperature makes it suitable in application where 304 will become sensitized, or where 304L has insufficient hot strength.
