Waht’s The Difference between 304and 316 Staubless Steel

When selecting a stainless steel that must endure corrosive environments,austenitic stainless steels are typically used. Possessing excellent mechanical properties, the high amounts of nickel and chromium in austenitic stainless steels also provide outstanding corrosion resistance.Two of the more commonly used grades of austenitic stainless steel are grades 304 and 316.

304 Stainless Steel

Grade 304 stainless-steel is commonly seemed because the maximum not unusualplace austenitic stainless-steel. It carries excessive nickel content material this is commonly among 8 and 10.5% with the aid of using weight and a excessive quantity of chromium at about 18 to 20%with the aid of using weight. Other foremost alloying factors consist of manganese, silicon, and carbon.The the rest of the chemical composition is more often than not iron.

The excessive quantities of chromium and nickel deliver 304 stainless steel first rate corrosion resistance. Common packages of 304 stainless-steel include:Appliances including fridges and dishwashers; Commercial meals processing equipment; Fasteners; Piping; Heat exchangers; Structures in environments that might corrode popular carbon steel.

316 Stainless Steel

Similar to 304, Grade 316 stainless-steel has excessive quantities of chromium and nickel. 316 additionally carries silicon, manganese, and carbon, with the bulk of the composition being iron. A primary distinction among 304 and 316 stainless-steel is the chemical composition, with 316 containing a considerable quantity of molybdenum; usually 2 to a few percentage with the aid of using weight vs only trace amounts found in 304. The better molybdenum content material outcomes in grade 316 owning expanded corrosion resistance.

316 stainless-steel is regularly taken into consideration one of the maximum appropriate picks whilst deciding on an austenitic stainless-steel for marine applications. Other not unusualplace programs of 316 stainless steel include:Chemical processing and garage equipment;Refinery equipment;Medical devices;Marine environments, specially people with chlorides present.

Here are some conditions where 304 stainless steel may be the better choice:

The application requires excellent formability. The better molybdenum content material in Grade 316 could have destructive results on formability.The application has cost concerns. Grade 304 is normally extra low cost than Grade 316.

Here are some conditions where 316 stainless steel may be the better choice:

The surroundings consists of a excessive quantity of corrosive elements.It could be positioned underwater or be uncovered to water consistently.In packages in which more strength and hardness are required.

And our produt stainless slide is made 304 material for outdoor playground slide.It has more features: 1.Corrosion Resistance; 2.Heat Resistance and Thermal Conductivity; 3.Low Temperature Strength;4.Good hot working performance in stamping and bending;5.Good machinability and weldability. 304 stainless steel has satisfactory weldability and processing performance in the process of welding. It is a good stainless steel sliding material.
