May 31, 2020 · AISI 304 Stainless Steel (UNS S30400) AISI 304 stainless steel (UNS S30400) is the most widely used stainless steel, containing 18-20% Cr and 8-10.5% Ni, and also known as 18-8 stainless steel.Type 304 is non-magnetic under annealing conditions, but after cold working (such as stamping, stretching, bending, rolling), part of the austenite Austenitic Stainless Steels - Iron-Chromium-Nickel Nitty AISI 202 Compared to the previous it presents higher percentages of Mn (9 instead of 7%) and Ni (5 instead of 4.5%). The resulting austenite is more stable and with the cold working becomes slightly magnetic. It is comparable to AISI 302, and it is a cheaper alternative while being less ductile in the annealed condition.

Can Oct 07, 2008 · The major differences between 202 and 304 stainless steels are in the nickel and chromium contents. 202 has 16-18% chromium and 0.5-4.0% nickel, whilst 304 has 18-20% chromium and 8-10.5% nickel. There are other minor differences in the amount of carbon (0.08% in 304 and 0.12% in 202), manganese (2% in 304 and 5.5-7.5% in 202), as well as slight differences in the silicon,
50Ti-50Ni atomic percent and a diameter of 3.5 mm was provided by Hsu-Yang Technologies Company. The size of the SUS 304 and AISI 1045 steel substrate specimens was 20×20×3 mm. The steel specimens were ground and degreased before cladding. The welding was carried out at a current of 85 A and an argon flow rate of 15 l/min. Heat input and shielding gas effects on the microstructure Sep 01, 2020 · The percentage of elongation was shown to decrease and the pitting corrosion resistance tended to increase. AISI 202-grade stainless steel is suitable for various the authors of this paper aimed to create an information data base related to welding AISI 202 grade low nickel stainless steel by studying the influence of heat input in
Jan 13, 2020 · A comparative study on 10-mm-thick AISI 316 weld joints fabricated using conventional 316L and Nb based stabilized AISI 347 filler was carried out. Welds were aged at 550 °C/50 hours and 750 °C/24 hours to induce a varying degree of precipitation. Nb in the case of 347 weld exhibited strong inhibition tendencies against chromium carbide precipitation besides preventing appreciable loss of Ni S eangan et al, aterial ci ng , Journal of Material 202 and AISI 300, e.g. 304, 302 and 316) is non-magnetic, ductile, nothardenable by heat treatment, and easily fabricated . Their major weakness is chloride stress corrosion cracking (SCC), being susceptible at temperatures over 55°C . Apart from chromium, austenitic SS typically contains 8 to 30% nickel and varying quantities of
For stainless and duplex applications that are 3 to 5 mm, when welding "flat and horizontal welds", consider an 0.035 MIG or 0.040 wire when using the Spray mode. I recommend my Argon - 2% CO2 mix. For stainless parts thicker than 1/4 ( > 6 mm), consider an 0.045 (1.2mm) MIG wire with MIG Spray and also with Argon - 2% CO2. Stainless Steel - General Information - Alloying Elements Manganese, like nickel, is an Austenite forming element and has been used as a substitute for nickel in the AISI200 Series of Austenitic Stainless Steels, e.g. AISI 202 as a substitute for AISI 304. Chromium (Cr):Chromium is added to steel to increase resistance to oxidation.
Nickel (Ni):Nickel is added in large amounts, over about 8%, to high Chromium stainless steels to form the most important class of corrosion and heat resisting steels. These are the Austenitic stainless steels, typified by 18-8 (304/1.4301), where the tendency of Nickel to form Austenite is responsible for a great toughness (impact strength) and high strength at both high and low temperatures. Stainless Steel - The Definitive Guide The same as nickel, manganese is an Austenite forming component and has been commonly used as an alternative for nickel in the AISI200 series of Austenitic stainless steels, for instance, AISI 202 as an alternative for AISI 304.
