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 SS 304 contains 18% chromium (Cr) and 8% nickel (Ni), its also known as 18/8 stainless steel. Type 304 has good processability, weldability, corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot AISI 304 Stainless SteelSpecification and Datasheet The SAE/ANSI 304 (AISI 304) is the most commonly available and used type of stainless steel. It is also referred to as 18/8 stainless steel, A2 stainless steel (as per the ISO 3506), or 304S15 (as per the British Standard). This is an austenitic chromium nickel alloy which practically means that it has a very high corrosion resistance.AISI Type 304 Stainless Steel MatWebHigh ductility, excellent drawing, forming, and spinning properties. Essentially non magnetic, becomes slightly magnetic when cold worked. Low carbon content means less carbide precipitation in the heat affected zone during welding and a lower susceptibility to intergranular corrosion.
AISI 304 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 304 is the AISI designation for this material. S30400 is the UNS number. Additionally, the British Standard (BS) designation is 304S15. And the AFNOR (French) designation is Z7Cn18 09.1.4301 (AISI 304), S30400 Datasheet METALCOR304. UNS. S30400. Description. 1.4301 / AISI 304 is the standard austenitic chromium nickel stainless steel. Special properties. High corrosion resistance. Easy formability. Not resistant to intergranular AISI 304 vs 304L Stainless Steel Properties (UNS S30403 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 content is 0.03%. The main purpose is to prevent carbide precipitation and improve weldability and corrosion resistance.
Mechanical Properties of AISI 304 & AISI 316 Stainless steels are divided into 5 familiesaustenitic, ferritic, martensitic, duplex (a mix of ferritic and austenitic) and PH precipitation hardening (martensitic, semi austenitic or austenitic).Mechanical properties and deformation mechanisms of Balusamy, T. et al.

Sci. 74 , 332344 (2013).Stainless Steel Grade 304Background Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics.
In this research, investigation of mechanical properties and microstructure on Pulsatile Current Gas Tungsten Arc Welding (PC GTAW) was carried out. AISI 304L was chosen as a base material with autogenous welding and butt joint configuration. The dimension of the base material was 120 x 50 mm and the thickness of 3 mm.Evolutions of mechanical properties of AISI 304L stainless The evolutions of microstructure and mechanical properties during shear punch testing (SPT) of an AISI 304L metastable austenitic stainless steel were studied at deformation temperatures ranging from 0 °C to 550 °C and strain rates in the range of 10 3 s 1 to 1 s 1.Based on the X ray diffraction (XRD) phase analysis and metallographic observations, it was inferred that by increasing the North American StainlessAISI 304 .
