The low carbon content reduces susceptibility to carbide precipitation during welding. In the present paper a thorough review on welding of AISI 304L austenitic 1.1.1 Austenitic stainless steels Stainless Steel by various welding processes was made. From the review it is understood that AISI 304L austenitic Austenitic stainless steels are Austenitic Stainless Steels - ASM Internationalpass welding of heavy section (greater than about 2 mm) or when welds requiring a post-weld stress relief are anticipated. Lean Alloys Lean austenitic alloys constitute the largest portion of all stainless steel produced. These are principally 201, 301, and 304. Alloys with less than 20% chromium and 14% nickel fall into this unofficial category.
The 204 steels can have up to 18% chromium and 0.5% nickel where the 304 can have up to 20% Differences Between 304 and 316 Stainless SteelDifferences Between 304 and 316 Stainless Steel 304 Stainless Steel. Type 304 is a grade of Stainless Steel with its chromium-nickel content and low carbon, is the most versatile and widely used of the austenitic stainless steels. Its alloys are all modifications of the 18% chromium, 8% nickel
304L stainless steel contains low carbon content compared to 304. It does have more nickel, standing at upmost 12 percent. This type of stainless steel is known for its durability and its use in food processing equipment, kitchen appliances, and fittings, among others. GRAINGER APPROVED Forged 304 Stainless Steel Socket Stainless Steel Socket Weld Pipe Fittings Class 150 150 psi WOG at 150°F 316 stainless steel has a higher nickel content to provide better corrosion resistance than 304 stainless steel. For plumbing or welding applications with air, water, natural gas, or steam. Materials conform to ASTM-A-351. Dimensions conform to ANSI B16.5.
The most important thing to keep in mind is choosing the right electrode for the job, some of the most common electrodes recommended for welding stainless steel are 316, 308, 312, and 309. If you are not sure about which electrode to use for a particular grade of steel, make sure to ask a professional or the manufacturers recommendation. How To:MIG Welding Stainless SteelThe widely used stainless steel is the Type 304 stainless steel as they are also referred to as surgical stainless steel as it contains a maximum of 20% of chromium and 10% of nickel.
Stainless steel types 1.4301 and 1.4307 are also known as grades 304 and 304L respectively. Type 304 is the most versatile and widely used stainless steel. It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel. 304 L Stainless Steel Stainless Steels Welding Guide - Lincoln Electricmartensitic stainless steels. Steels with over 0.20% C often require a post weld heat treatment to soften and toughen the weld. 3.3 AUSTENITIC STAINLESS STEEL The austenitic stainless steels contain 16-26% Cr, 8-24% Ni + Mn, up to 0.40% C and small amounts of a few other elements such as Mo, Ti, Nb (Cb) and Ta. The balance between the Cr and Ni + Mn is normally
Jan 11, 2020 · Type 304 is the most widely used austenitic stainless steel. It is also known as "18/8" Weldability of Materials - Stainless Steel - TWIAustenitic stainless steels typically have a composition within the range 16-26% chromium (Cr) and 8-22% nickel (Ni). A commonly used alloy for welded fabrications is Type 304 which contains approximately 18%Cr and 10%Ni. These alloys can be readily welded using any of the arc welding processes (TIG, MIG, MMA and SA).

Welding Guidelines for Stainless Steel and Nickel AlloysGenerally, best practice is to use the filler metal designed for the higher alloyed of the two. For example, if joining 304L to 316L base metals, use 316L filler metal. When joining stainless steel to nickel base alloys always use nickel base filler metals.
May 24, 2019 · Welding methods. The test materials are SA387 GR22 CL2 plate and 304 stainless steel plates, with specifications of 400mm 150mm 10mm. The chemical compositions of the two materials are shown in the following table. In order to reduce the dilution of the welding seam and prevent the occurrence of cold crack and reheat crack, the welding method Welding of austenitic stainless steels for cryogenic LNG 304 L Stainless steel type AISI 304 L 9 Ni 9 % Ni Steel Storage tanks Figure 2:Typical applications of established base materials used for LNG 
304/304L STAINLESS STEEL Product Description Type 304 is a variation of the base AK Steel 18-8, with a higher chromium and lower carbon content. The lower carbon content minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. In some instances Type 304 can be used in the "as-welded" condition.
