Product Description 316L IntroductionGrade 316L, the low carbon version of 316 and is immune from sensitization (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel.The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures. 316L Chemical composition Composition ranges for 316L stainless steel.Grade CMnSiPSCrMoNiN316LMin-----16.02.0010.0-Max0.032.00.750.0450.0318.03.0014.00.10 316L Mechanical PropertiesMechanical properties of 316L stainless steel.GradeTensile Str (MPa) minYield Str 0.2% Proof (MPa) minElong (% inElong (% in 50 mm) min50 mm) minHardnessRockwell B (HR B) maxBrinell (HB) max316L4851704095217 316L Physical PropertiesTypical physical properties for 316-grade stainless steels.GradeDensity (kg/Density (kg/m3)m3)Elastic Modulus (GPa)Mean Co-eff of Thermal Expansion (μm/m/°C)Thermal Conductivity (W/m.K)Specific Heat 0-100 °C (J/kg.K)Elec Resistivity (nΩ.m)0-100 °C0-315 °C0-538 °CAt 100 °CAt 500 °C316/L/H800019315.916.217.516.321.5500740 316L Grade SpecificationGradeUNSJISENAMSASTMBS316LUNS S31603SUS 316L1.4404 316S11316L CharacteristicCorrosion ResistanceExcellent in a range of atmospheric environments and many corrosive media - generally more resistant than 304. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60 °C. Considered resistant to potable water with up to about 1000 mg/L chlorides at ambient temperatures, reducing to about 500 mg/L at 60 °C.316 is usually regarded as the standard "marine grade stainless steel", but it is not resistant to warm seawater. In many marine environments, 316 does exhibit surface corrosion, usually visible as brown staining. This is particularly associated with crevices and rough surface finish.Heat ResistanceGood oxidation resistance in intermittent service to 870 °C and in continuous service to 925 °C. Continuous use of 316 in the 425-860 °C range is not recommended if subsequent aqueous corrosion resistance is important. Grade 316L is more resistant to carbide precipitation and can be used in the above temperature range. Grade 316H has higher strength at elevated temperatures and is sometimes used for structural and pressure-containing applications at temperatures above about 500 °C.Possible Alternative GradesPossible alternative grades to 316 stainless steel.GradeWhy it might be chosen instead of 316?317LHigher resistance to chlorides than 316L, but with similar resistance to stress corrosion cracking.TechnologyHeat TreatmentSolution Treatment (Annealing) - Heat to 1010-1120 °C and cool rapidly. These grades cannot be hardened by thermal treatment.WeldingExcellent weldability by all standard fusion and resistance methods, both with and without filler metals. Heavy welded sections in Grade 316 require post-weld annealing for maximum corrosion resistance. This is not required for 316L.316L stainless steel is not generally weldable using oxyacetylene welding methods.Machining316L stainless steel tends to work harden if machined too quickly. For this reason, low speeds and constant feed rates are recommended.316L stainless steel is also easier to machine compared to 316 stainless steel due to its lower carbon content.Hot and Cold Working316L stainless steel can be hot worked using the most common hot working techniques. Optimal hot working temperatures should be in the range 1150-1260 °C, and certainly should not be less than 930 °C. Post-work annealing should be carried out to induce maximum corrosion resistance.Most common cold working operations such as shearing, drawing, and stamping can be performed on 316L stainless steel. Post-work annealing should be carried out to remove internal stresses.Hardening and Work Hardening316L stainless steel does not harden in response to heat treatments. It can be hardened by cold working, which can also result in increased strength.Applications316L steel has a wide range of applications in the medical field, mainly used to manufacture various medical devices and implants.316L steel is a medical grade stainless steel that is highly corrosion resistant, high temperature resistant, and easy to clean and disinfect. Its main components include 18% chromium, 12% nickel, and 2.5% molybdenum, which make it excellent in corrosion resistance. In addition, 316L steel also has good biocompatibility and is suitable for manufacturing medical devices implanted in the human body, such as artificial joints and bone nails.In the medical industry, 316L steel is often used to manufacture the following medical devices and equipment: Surgical instruments: such as scalpels, forceps, tweezers, etc. These instruments need to have excellent corrosion resistance and mechanical properties to ensure safety and reliability during surgery.Implants: such as artificial joints, pacemakers, etc. These implants need to be compatible with human tissues to avoid causing rejection reactions.Biomedical materials: such as stents, artificial valves, etc. These materials need to have excellent biocompatibility to ensure that long-term use in the body will not cause adverse reactions.The excellent performance of 316L steel makes it indispensable in the medical field. Its acid resistance, oxidation resistance and temperature resistance enable it to maintain excellent stability even in extremely harsh use environments. In addition, 316L steel also has good mechanical properties and weldability, further expanding its application range in the medical field.
