SAE steel grades. The SAE steel grades system is a standard alloy numbering system (SAE J1086 - Numbering Metals and Alloys) for steel grades maintained by SAE International . In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
This article will introduce the differences between 304 and 304L stainless steel (304 vs 304L) from chemical composition, mechanical properties, corrosion resistance and weldability. AISI 304L stainless steel is an ultra-low carbon version of SS 304 (Carbon content: ≤ 0.08 %). "L" is short for "Low carbon" and the maximum carbon
AISI 304 / UNS S30400 / DIN 1.4301 18/8 Chrome-Nickel Austentic Alloy Alloy 304 is chrome-nickel austenitic alloy, it is also known as 18/8 grade which states 18% chromium & 8% nickel . It can be deep drawn resulted it being the superior grade. It have also
Non esiste una significativa differenza di impiego tra i due gradi, entrambi sono ottimi e resistenti nella maggior parte delle situazioni. C'è da dire che in generale i tubi senza saldatura AISI 304 sono più competitivi a livello economico e hanno una maggiore lavorabilità a caldo, che nell'AISI 316 cala leggermente per l'aggiunta di
Im amerikanischen AISI System (American Iron and Steel Institute) kennt man unter den Nummern 304 und 304L folgende Stähle: 1.4301 – X5CrNI18-10 (AISI 304) 1.4307 – X2CrNiMo13-4 (AISI 304L) 1.4306 – X2CrNi19-11 (AISI 304L) Die Edelstahllegierungen AISI 304 und AISI 304L sind die bekanntesten und am meisten verwendeten Chrom-Nickel …
AISI 304 stainless steel (UNS S30400) is the most commonly used material in stainless steels, and is usually purchased in an annealed or cold worked state. Because SS304 contains 18% chromium (Cr) and 8% nickel (Ni), it's also known as 18/8 stainless steel. Type 304 has good processability, weldability, corrosion resistance, heat resistance
