![]() The alloy finds use in a variety of commercial applications and is one of the widely used stainless steel grades. Not only because of its incredible welding characteristics. Offering excellent welding and forming properties, the alloy is also reasonably machinable. 304 Stainless Steel is the ideal grade to use for any of your form or welding projects. L is short for Low carbon and the maximum carbon. AISI 304L stainless steel is an ultra-low carbon version of SS 304 (Carbon content: 0.08 ). Grade 304 is very ductile when in an annealed condition. This article will introduce the differences between 304 and 304L stainless steel (304 vs 304L) from chemical composition, mechanical properties, corrosion resistance and weldability. It is a chromium-nickel austenitic stainless steel with relatively low carbon content and somewhat higher chromium and nickel than AISI types 301 and 302. It is used in heavy gauge components for improved weldability. Stainless Steel 304 is the most widely used stainless steel grade. 304L Stainless Steel Type 304L is the low carbon version of Stainless steel 304. This property has resulted in 304 being the dominant grade used in applications like sinks and saucepans. Before annealing, the surface should be carefully cleaned, and to prevent the formation of an oxide layer during the annealing process, vacuum, hydrogen or inert gas protection must be used. ![]() Type 304 stainless steel is an austenitic stainless steel alloy which contains 18% chrome and 8% nickel. Stainless steel 304 is an austenitic grade that can be severely deep drawn. Type 304 stainless steel annealing temperature range is 1010-1065 C (1850-1950 F),1040 C (1900 F) is recommended and then rapidly cooled. Type 304L is the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge components (over about 6mm). A combination of low yield strength and high elongation allows for the forming of complex shapes, although it should be noted that the material hardens rapidly. Stainless steel 304 is an austenitic grade of stainless steel that contains high nickel content, typically somewhere between 8 and 10.5 percent by weight and a. The alloy also benefits from very good drawability. Keep in mind, not all 304 stainless is created equal, as some have a. Weldability and forming properties of Type 304 are excellent whilst machinability is reasonable. Stainless Steel 304 is the most versatile and widely used of all the stainless steels. ![]() The alloy has a lower carbon content which minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. Below is a chemical breakdown of 304 steel: <0. Type 304 stainless steel is an austenitic alloy containing 18% chrome and 8% nickel. Type 304 steel is part of the 3xx stainless steels or those alloys which are blended with chromium and nickel. Offering excellent corrosion resistance at an affordable price point, Alloy 304 is the worlds most widely used stainless steel type.
