Stainless steel is a versatile material which is widely used in various industries due to its good traits and highly unmatched characteristics. The steel has various grades in it that are used in the fabrication process of heat exchangers tubes. The grade 316L of Stainless steel is the standard molybdenum grade among the austenitic stainless steels. The presence of molybdenum in 316 provides overall resistive properties as compared with other SS grade 304. It offers good resistance to corrosive environment, pitting resistance to chloride environment and crevice corrosion resistance properties.

Basic Information

Generally, Heat Exchangers Tubes are a device which is used to transfer heat between the fluids. These exchangers are widely used in many industries. The material used in the fabrication of these tubes is stainless steel commonly. The 316L is popularly used in the manufacturing of exchanger’s tubes. It is known to be the lower carbon version of 316 grades which has its specialty in resisting to carbide precipitation.

Due to its good mechanical properties, it is commonly used in the manufacturing of heat exchanger tubes. The austenitic structure of this grade enhances its hardness and toughness even at the cryogenic temperatures. Furthermore, the grade offers good creep properties, higher stress to rupture and excellent tensile strength at high temperature.
