Type 316L(CF3M) is the low carbon version of 316 stainless. Again compared to 304/304L having the addition of molybdenum, the steel is popular for use in severe corrosion environments due to the materials immunity from boundary carbide precipitation (sensitisation) caused by welding.
Weld annealing is only required where the material is for use in high stress environments. 316L has an extensive variety of uses especially in highly corrosive applications.
Benefits of using type 316L stainless steel
Low carbon content eliminates carbon precipitation in the welding process
Can be used in severe corrosive environments
Improved anti-corrosion scope due to added molybdenum
Very similar to Grade 316 in chemical composition and mechanical properties
316 & 316L valves have common properties and are often stocked by Global Supply Line with dual certification, where it is determined that both have properties and composition which comply with both steel types.
All the time, Longzhu adheres to a quality policy of "Treating People with Sincerity, Seeking for Prosperity with Quality" and a principle of "Reputation First, Quality First", sets up an industry-leading modern quality inspection and test center, and tests outgoing products strictly with direct-reading spectrometer, fluorescent magnetic particle inspection, all-digital ultrasonic fault detectors, screen display hydraulic pressure universal testers, radiographic testing machine, coordinate Measuring Machine, molten steel thermocouple thermometer and other inspection devices. So far, Longzhu has obtained the CE certification of the EU and the ISO9001 Quality Management System certification relying on its reliable product quality.
