What is the difference between AISI 304 and SS 304?
What is the difference between AISI 304 and SS 304?
SUS304 (SUS meaning Steel Use Stainless) stainless steel austenite is typically known as the Japanese name for SS304 or AISI 304. The main difference between the two materials is not any physical property or feature, but how it is referenced in American and Japanese grades.
What does AISI stand for in stainless steel?

What is the difference between AISI 304 and AISI 316?
The simple answer is 304 contains 18% chromium and 8% nickel while 316 contains 16% chromium, 10% nickel and 2% molybdenum. The molybdenum is added to help resist corrosion to chlorides (like sea water and de-icing salts).27 Sept 2012
What is the meaning of AISI 316?
AISI 316 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 316 is the AISI designation for this material. S31600 is the UNS number. Additionally, the British Standard (BS) designation is 316S16.
Is AISI 304 stainless steel?
AISI 304 (1.4301) is a widely-used austenitic chromium-nickel stainless steel. It has excellent drawing properties and very good formability, while it is also highly corrosion-resistant. Typical uses of 304 stainless steel include sinks, kitchen equipment such as pans, tubing and much more.
What is the difference between AISI and SS?
Stainless steels, thanks to their chemical composition, are metal alloys, which are naturally corrosion resistant. AISI316L stainless steel, known as 1.4404, is different from AISI 316 (1.4491) stainless steel because it has less carbon inside. On the contrary, in AISI 316 it must be ≤ 0,07.
Is all 304 stainless steel the same?
304, 304H and 304L all possess the same nominal chromium and nickel content and thus possess the same corrosion resistance, ease of fabrication and weldability.
Is stainless steel 304 toxic?
Toxicity: Does stainless steel release anything, and if so, what? Common food/medical-grade stainless steel (18-8 or 18-10, 304 grade) can release trace amounts of certain elements but the higher the quality of the stainless steel, the less the leaching.
What is AISI 304 used for?
What is AISI 304? AISI 304 (1.4301) is a widely-used austenitic chromium-nickel stainless steel. It has excellent drawing properties and very good formability, while it is also highly corrosion-resistant. Typical uses of 304 stainless steel include sinks, kitchen equipment such as pans, tubing and much more.
How can you tell if stainless steel is food grade?
For example, food grade stainless steel of 18/8 is 18 percent chromium and 8 percent nickel. 304 grade stainless steel also has to have no more than 0.8 percent carbon and at the very least 50 percent or iron. There are no other substances such as aluminium included in the creation of this grade of steel.
What can cause 304 stainless steel to rust?
Exposure to corrosive process fluids and cleaners, high humidity or high salinity environments such as sea water can remove the native protective layer (chromium oxide) and can cause stainless steel corrosion. Removing surface rust from surfaces improves the appearance, but it's importance goes beyond the decorative.
Is 304 stainless steel suitable for outdoor use?
In contrary to other metals which are vulnerable to moisture and require various protective coatings to be made suitable for outdoor use, grade 304 stainless steel is resistant to corrosion as well as other harsh outdoor elements.
What grade of stainless steel will not rust?
With the high nickel and chromium content, the 304 grade of stainless steel offers excellent protection against corrosion.28 Jul 2017
