Is AISI 304 same as SS304?
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 304 stand for?
American Iron and Steel Institute
Grade Meaning AISI stands for American Iron and Steel Institute. Therefore, both grade 304 stainless steel and grade 316 conform to the American standard. The European equivalents are 1.4301 and 1.4401, respectively.
What is the difference between AISI 304 and AISI 316?
316 contains many similar chemical and mechanical properties as 304 stainless steel. To the naked eye, the two metals look the same. However, the chemical composition of 316, which is made up of 16% chromium, 10% nickel, and 2% molybdenum, is the main difference between 304 and 316 stainless steel.
What is type 304 stainless steel?
304 stainless steel is the most common form of stainless steel used around the world, due to its excellent corrosion resistance and value. It contains between 16 and 24 percent chromium and up to 35 percent nickel, as well as small amounts of carbon and manganese.
What is AISI steel stands for?
the American Iron and Steel Institute
Back in the 1930s and 1940s, the standards organization SAE International and the American Iron and Steel Institute (AISI) began working to standardize a numbering system for stainless steel.
Is all 304 stainless steel the same?
Carbon content 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. The difference between 304, 304H and 304L is the carbon content which is >0.03, >0.05 and <0.03 respectively.
What does AISI mean in steel?
Is AISI 304 magnetic?
The austenitic stainless steel grade 304 is not magnetic but it may become a little magnetic in areas that have been cold working (bending, deforming, etc.).
What is AISI classification?
Grading of AISI Materials A basic four-digit system is used by the SAE system to designate the chemical composition of alloy steels and carbon steels. There is a possibility that AISI grades are quoted as SAE grades and very often the same steel identification number is present in AISI/SAE standards.
What are AISI codes?
A four-digit number is usually given to the AISI alloy steels and carbon steels. The alloying element in the AISI specification is indicated by the first two digits and the amount of carbon is indicated by the last two digits.
What do AISI numbers mean?
Definitions. The four-digit identification number used to designate carbon steel coils. AISI stands for the American Iron and Steel Institute. The first two digits in the AISI number indicate the grade of steel, while the last two digits give the amount of carbon in the steel.
What is werkstoff number?
Werkstoff numbers The numeric code is the Werkstoff number, this uses numbers only with a decimal point after the first digit. Werkstoff – material, the stuff something is made from. Below is a table of some of the more popular steel grades we supply along with the BS 970 1991, AISI/SAE and Werkstoff equivalents.
What is AISI in technical drawing?
1. AISI – American Iron and Steel Institute. The American Iron and Steel Institute (AISI) is an association of North American steel producers. Its predecessor organizations date back to 1855 making it one of the oldest trade associations in the United States.
