With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Grade 321H is a modification of 321 with a higher carbon content, to provide improved high temperature strength. A limitation with 321 is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable.
The titanium content of 321 stainless steel preserves corrosion resistance around weld points. This material maintains its corrosion resistance in temperatures up to 1500 F.
321 Stainless Steel Sheet, Coil, Plate & Bar - AMS 5510, 5645. 321 is a titanium stabilized austenitic chromium-nickel stainless steel which was developed to provide an 18-8 type alloy with improved intergranular-corrosion resistance. This material is stabilized against chromium carbide formation by the addition of titanium.

Alloy 321 (UNS S32100) is stabilized stainless steel plate 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 1500F (427 to 816C).
Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 8001500F (427816C). The alloy resists oxidation to 1500F (816C) and has higher creep and
Type 321 is particularly useful under conditions which cause polythionic acid stress corrosion of non-stabilized austenitic stainless steels such as Type 304. Exposure of non-stabilized austenitic stainless steel to temperatures in the sensitizing range will cause the precipitation of chromium carbides at grain boundaries.
321 stainless is a titanium stabilized grade commonly used for service in the 1000-1600F temperature range. For service temperatures up to about 1600F, a stabilizing treatment at 1550-1650F, air cool, may be used to provide optimum resistance to intergranular corrosion and to polythionic acid stress corrosion cracking.
321 is similar to 304, but uses titanium as a stabiliser. They differ in that they are resistant to intergranular corrosion after heating to temperatures in the carbide precipitation range. Applications include aircraft exhaust manifolds, furnace parts, heat exchangers, furnace parts etc.
321 is a titanium stabilised chromium-nickel austenitic stainless steel with good strength and excellent corrosion resistance, as supplied in the annealed condition with a typical brinell hardness of 175.Characterised by high corrosion resistance in general atmospheric corrosive environments it exhibits excellent resistance to most oxidizing agents, general foodstuffs, sterilizing solutions, dyestuffs, most organic chemicals plus a wide variety of inorganic chemicals, also hot petroleum 321 steel hardness
** This conversion calculator gives approximate hardness values for various hardness scales based on the Rockwell C Scale. The Hardness Tensile Strength relations may vary according to the processing history or the chemical composition of the steel.
Type 321 exhibits excellent resistance to organic chemicals, dyestuffs, and a wide range of inorganic chemicals. It resists nitric acid well and the sulfur acids moderately. Long-time exposure in the 900 -1500F range may lower its general corrosion resistance, but the grade still shows improved resistance to intergranular corrosion compared to unstabilized grades.
1.4541, X6CrNiTi18-10, AISI 321 - specifications and applications Chrome-nickel stainless steel with addition of titanium with increased hardness, elasticity, maintaining non-magnetic properties, resistance to intergranular corrosion and increased temperatures.

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. Type 321 is used where resistance to intergranular corrosion is required and where the parts are subjected to sustained heating or cooling within the range of 800 to 1500F.
321 Stainless Steel Plate 321 stainless steel plates are part of the austenitic family of stainless steel. 321 is basically a 304 grade containing a stabilizer of titanium. Type 321 is a good choice for applications where heat is an issue. 321 can be used in applications up to 900C where 304 is normally used up to 500C.

Stainless Steel - Grade 321 CS 321 Technical Data . CS 321 is a titanium-stabilised version of CS 304, used in particular applications within the sensitizing temperature range.
321 is an austenitic stainless steel that is melted as AOD melt type. This is a stabalized version of 304 stainless to help improve intergranular corrosion resistance. This alloy is similar to 347 stainless except uses titanium to stabilize the carbon instead of niobium.
1.4541 / AISI 321 is an austenitic chromium-nickel-stainless steel, stabilized with titanium. Special properties Good corrosion resistance to low content of hydrochloric and organic acids.
Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel 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).
Note 2: Hardness specication limits given are HRB = Rockwell B scale, HRC = Rockwell C scale, HB = Brinell Hardness. Note 3: 3CR12 generally conforms with both ASTM A240 grade S41003 and with EN 10088 Parts 1 and 2, grade 1.4003.
The key feature of 321 Stainless Steel is its resistance to intergranular corrosion. 321 Stainless Steel also has low risk of weld decay due to addition of Titanium. Type 321 Stainless steel is similar to Type 304 Stainless Steel, however, it contains a Titanium addition of at least five times the carbon content.
Titanium-bearing, austenitic, chromium-nickel steel. Stabilized against carbide precipitation and designed to work within the temperature range where carbide precipitation develops. Similar to Type 304 except Ti content helps prevent chromium carbide precipitation resulting from welding or elevated temperatures.
Grade 321 stainless steel (1.4541) is a heat resistant grade supplied into numerous industry sectors. The key property of this grade is the added titanium content (5 x C%) stabilising the material and making its resistance to carbide precipitation when exposed to high temperatures and resistance to oxidation its main characteristics.
