What is SUS 304 Vs SS 304?
The material SUS304 is a Japanese JIS Standard and one of the most often used stainless steels, comprising 18% Cr and 8% Ni. In elevated temperature and low-temperature environments, it can remember excellent strength and heat resistance, and at room temperature, it also has excellent corrosion resistance, weldability, cold workability, and mechanical characteristics.
AISI 304 stainless steel is the material most regularly used in stainless steels and is usually bought in hardened or cold condition. Since SS 304 includes 18% chromium (Cr) and 8% nickel (Ni), stainless steel is also known as 18/8. SS 304 has excellent processability, weldability, resistance to corrosion, heat resistance, low-temperature strength and mechanical characteristics, excellent warm workability such as stamping and bending, and no hardening of heat treatment. SS 304 is generally used in industrial applications, decoration of furnishings, food, and medical industries, etc.
SUS 304 Stainless Steel austenite is usually mentioned to as the Japanese name for stainless steel SS304 or AISI 304. Except that the two grades are the reference in Japanese and American grades, there is no significant distinction. Some individuals attempt to explain the mechanical properties distinction. A sample of stainless steel SUS304 assembled from a Japanese source, and an example of stainless steel 304 an American source gained. Both samples sent for testing in a mechanical lab.
SUS 304 vs SS 304 Chemical Composition:-
|Steel Grade||SUS 304||SS 304|
SUS 304 vs SS 304 Physical Properties:-
|Density(g/cm3)||Melting point (℃)||Specific heat (J/kg·℃)||Electrical resistivity (μΩ·m) (20℃)||Thermal expansion (10-6/K)||Thermal conductivity (W/m·K)|
|SUS304 Material Physical Properties ≤||7.93||1,400-1,450||460-502||0.73||17.8 (20-300℃)||16.8 (100℃)|
|SS 304 Material Physical Properties||7.93 g/cm3||1398-1454 ℃||500 J/(Kg·K) at 0-100℃||0.73 μΩ·m (20℃)||17.8 (0-300℃||16.3 (100 ℃)|
CORROSION RESISTANCE :-
In a broad range of atmospheric settings and many corrosive media, stainless steel grade 304 is outstanding. In warm chloride environments, it is subject to pitting and crevice corrosion and stresses corrosion cracking above 60 ° C (approximate). Grade 304 is considered to be resistant to drinking water at ambient temperatures up to about 200 mg / L of chloride, reducing it to about 150 mg / L at 60 ° C.

|GRADE||UNS NO.||OLD BRITISH||EURONORM||SWEDISH SS||JAPANESE JIS|
Grade 304 has outstanding weldability with and without filler metals through all conventional fusion techniques as 1554.6 pre-qualifies were 304 welding with Grade 308 and 304L with 308L tubes or electrodes (and their elevated equivalents in silicon). For peak corrosion resistance, substantial welded segments in grade 304 may involve post-welded annealing. This not need for Grade 304L. If heavy section welding is required and post-weld heat action is not feasible, Grade 321 may also use as an option to 304.
In the heated portion, basic corrosion called intergranular corrosion can happen when welding stainless steel, so if weldability is giving priority, it has specialized for this intergranular corrosion resistance. You can also choose a grade of stainless steel. Metals have a great picture at elevated temperatures, but when used in a cryogenic environment they may become fragile and crack, but it is known that SUS304 is a remaining grade of steel for fracture toughness in these settings. A lot of austenitic stainless steel comes from adding and removing different alloy components based on this SUS304, so it’s a starting material that can be said to be the mother of other SUS components.
Each Stainless Steel 304 vs SUS 304 is otherwise designed based on the characteristics of the applying and additionally the pressure. Consequently, different industries use different Stainless Steel 304 and SUS 304. We also produce customized Stainless Steel Products at our factory as per our client’s requirements.
