304 304L belongs to austenitic stainless steel, it is the most widely used in the 300 series materials. On the whole, the 304 304L has very similar characteristics, the only difference lies in the level of carbon content, so there will be a little difference more or less in the application filed, but the overall application is the same.
304L has lower carbon content and better corrosion resistance. But 304 of the strength is higher than 304L, so 304 has a higher strength than 304L.From the application: 304 can be widely used in various departments, various fields. 304L is mainly used in welding and other fields.
Details for 304 material:304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processing performance, high toughness characteristics, widely used in industrial and furniture decoration industry and food industry.
Details for 304L material:304L steel as a low C in the general state, its corrosion resistance and 304 similar, but after welding or stress after its excellent corrosion resistance to the grain boundary. In the case without heat treatment, can remain good corrosion resistance, generally use 400 or less (non-magnetic, temperature -196 degrees Celsius to 800 degrees Celsius). Widely used to produce good overall performance requirements (corrosion resistance and formability) of equipment and parts.

Applications
Applications for 304 material
Because 304 with good processing properties, high toughness characteristics, widely used in industrial and furniture industry and the medical industry food etc filed.What’s more 304 stainless is Suitable for food processing, storage and transportation,Plate type heat exchanger, corrugated pipe, household appliances (1, 2 kinds of tableware, kitchen cabinet, indoor pipeline, water heater, boiler, bath), auto parts (windshield wiper, muffler, mold), medical appliances, building materials, chemical, food industry, agriculture, marine parts etc..304 stainless steel is a nationally recognized food grade stainless steel.
Applications for 304L material
Usually 304L material with the same usage with 304 material.It’s the best choice for building material,decoration material and food industrial.But 304L with lower carbon content,so 304L is widely used in welding filed.
The Different Standards
Stainless Steel Strip
Stainless steel strip is simply an extension of an ultra thin stainless steel plate. A narrow and long steel plate produced mainly in order to meet the needs of industrial production of various metals or mechanical products in different industrial sectors.Actually,stainless steel is produced by stainless steel coil.Usually use the slitting machine to process it into strip,with the same usage with stainless steel coil.
309/309S stainless steel coil
309/309S stainless steel
309S is cutting stainless steel containing sulfur, the main requirements for cutting and surface finish high occasions. Widely used in important areas boilers, energy (nuclear power, thermal power, fuel cells), industrial furnaces, incinerators, furnaces, chemical, petrochemical, and other.
The only difference is that 309 stainless steel does not contain sulfur, and now basically produce steel 309S material. Both can be summed up as the same material.,have the same purpose.To some extent, the carbon content of 309S is lower than 309.
316/316L stainless steel coil
About 316 material:316 stainless steel by adding Mo element, the corrosion resistance, and high temperature strength has greatly improved, high temperature can reach 1200-1300 degrees, can be used in severe conditions.Corrosion resistance is better than 304 stainless steel, in pulp and paper production process has good corrosion resistance. And 316 stainless steel is also resistant to erosion of marine and corrosive industrial atmosphere. About 316L material: 316L stainless steel has a carbon content of less than 316, which is commonly used in pulp and paper equipment heat exchangers, dyeing equipment, film washing equipment, pipelines, coastal areas outside the building materials. Corrosion resistance is better than 316 material. Chemical Composition and Mechanical Property
