Overview of 316L Stainless Steel:
316L stainless steel belongs to the American century austenitic stainless steel series products, is a classic stainless steel composition modification alloy, in order to improve the corrosion resistance and the development of a type of ultra-low carbon stainless steel, with excellent seawater corrosion resistance, grain boundary corrosion resistance and high temperature mechanical properties, is currently widely used austenitic stainless steel. 316L austenitic stainless steel is widely used in petroleum, chemical and nuclear power fields due to its excellent corrosion resistance and comprehensive mechanical properties.
Chemical Composition of 316L Stainless Steel:
Difference Between 304 Stainless Steel and 316L Stainless Steel:
What is the difference between 304 stainless steel and 316 stainless steel.
1. The chemical composition is different: 304 does not have platinum, while 316 has platinum.
2. Different corrosion resistance: 304 contains only 9% of nickel elements, while 316 contains 12% of nickel elements, so the corrosion resistance of 304 is worse.
3. Different performance: 304 has better corrosion resistance, acid resistance, alkali resistance, etc., while 316 has better chloride corrosion resistance and heat resistance due to the addition of platinum elements.
4. The scope of application is different: 304 is widely used to make pots and pans, etc., while 316 is widely used in the food industry, medical industry, watch industry, etc.
5. **Different: Since 316 belongs to food grade and has better corrosion resistance, 316's ** will be more expensive than 304.
Effect of Surface Treatment on the Properties of 316L Stainless Steel Powder Injection Molding:
1) The surface of the 316L powder was successfully coated with PEG-EP, and the compatibility between PEG-EP and polyoxymethylene was good.
2) The dispersion between the 316L powder with different mass fractions of PEG-EP surface treatment is more uniform, and the affinity and wettability between the 316L powder and the binder are improved, so that the rheological properties and mechanical properties of the 316L powder injection molding green body are improved, and the mass fraction of 0The 662% PEG-EP component had the best comprehensive performance.
3) For 316L powder injection molding sintered specimens with different mass fractions of PEG-EP surface treatment, the mass fraction of PEG-EP was increased from 0 to 0At 662%, the sintering activity of the 316L powder sintered specimen was significantly improved, the grain structure was refined, and the mechanical properties and hardness were increased by 159 MPa and 17 HV, respectivelyWhen the PEG-EP mass fraction increases to 0At 990%, the grain size becomes larger and the comprehensive mechanical properties decrease.
