304/304Lstainless steel
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.
321 stainless steel plate
About 321 stainless steel
321 stainless steel belongs to austenitic stainless steel, its performance is very similar to the 304, but due to the addition of the metal titanium, it has a better intergranular corrosion resistance and high temperature strength. The addition of titanium, making it effective control of the formation of chromium carbide.
Excellent high-temperature stress of 321 stainless steel with a breaking (Stress Rupture) properties and high temperature creep resistance (Creep Resistance) stress mechanical properties are superior to 304 stainless steel.
310/310S stainless steel plate
310/310S stainless steel
310 stainless steel austenitic chromium nickel stainless steel has good oxidation resistance, corrosion resistance, because the higher percentage of chromium and nickel, 310 has much better creep strength, can continuously work under high temperature, good heat resistance.
310S stainless steel is austenitic chromium nickel stainless steel, has a good 310S stainless steel oxidation resistance, resistance Corrosive.
Because of the high percentage of chromium and nickel, which has a much better creep strength, can continue to work at high temperature, with good heat resistance.
Due to the high content of nickel (Ni), chromium (Cr), good oxidation resistance, corrosion resistance, acid and alkali resistance, high temperature resistance, high temperature resistant steel pipe is used in the manufacture of electric furnace tubes and other occasions.
The only differences for 310 310S stainless steel is the 310 stainless steel does not contain sulfur elements.What’s more,the carbon content of 310S is much lower than 310.
