Stainless Steel 304 (1.4301) is the most widely used stainless steel grade in the world. This grade is used at least one third of all stainless steel products. This grade is written as 1.4301 or X5CrNi18-10 according to EN norm and it is written as UNS S30400 according to UNS norm. This grade can be also shown as 18-8 or 18-10 and these numbers indicate the chromium and nickel percentages of the material. This grade can be weld easily and machinability of this grade is good. For better corrosion resistance, 316 or 316L could be a good alternative and for better machinability 303 grade can be a good alternative.
304 grade stainless steel has a really good price/performance and because of its good price/performance, 304 grade used very widely in many different applications. It is a very widely used stainless steel grade and it is really easy to find this stainless steel grade in any shape and in any size. In daily life, most of the stainless steel products around us are produced with 304 (1.4301) stainless steel grade.
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.
SS304 stainless steel is an austenitic grade that can be severely deep drawn. This property has resulted in 304 being the dominant grade used in applications like sinks and saucepans.
SS304L is the low carbon version of 304. It is used in heavy gauge components for improved weldability. Some products such as plate and pipe may be available as “dual certified” material that meets the criteria for both 304 and 304L.
304H, a high carbon content variant, is also available for use at high temperatures.
