Excellent Corrosion Resistance of Stainless Steel-316L Stainless Steel

Dear viewers, today we are going to talk about an amazing material - 316L stainless steel. Did you know? This ordinary-looking material has amazing corrosion resistance! 316L stainless steel as a low carbon series of 316 steel, in addition to the same characteristics with 316 steel, its resistance to grain boundary corrosion is excellent, let's take a look at it!

First, let's understand the background of 316L stainless steel. It is a kind of austenitic stainless steel, due to the addition of Mo elements, so that its corrosion resistance, and high temperature strength has been greatly improved, high temperature resistance can reach 1200-1300 degrees, can be used in harsh conditions. This is a widely used in aviation, medical, chemical, food and other fields of materials, has excellent corrosion resistance and high temperature resistance. It was born from the extreme pursuit of material performance. The corrosion resistance of stainless steel mainly depends on the chromium it contains. 316L stainless steel has a high chromium content of 16%, which can effectively resist the erosion of acids and alkalis. In addition, it also contains a high level of nickel, which enhances the corrosion resistance of the material, making its service life longer than ordinary stainless steel.

Processing technology: SLM laser metal powder melting


Material properties

1、Corrosion resistance. In the pulp and paper production process has good corrosion resistance. And 316L stainless steel is also resistant to marine and aggressive industrial atmospheres.

2, heat resistance. In the intermittent use below 1600 degrees and in the continuous use below 1700 degrees, 316L stainless steel has good oxidation resistance.

In the range of 800-1575 degrees, the stainless steel has good heat resistance. 316L stainless steel has better resistance to carbide precipitation than 316 stainless steel.

The characteristics exhibited by 316L steel are as follows:

1) Cold rolled products have a good and beautiful appearance; 

2) Excellent corrosion resistance, especially pitting resistance, due to the addition of Mo; 

3) Excellent high temperature strength ;

4) excellent work-hardening properties (weak magnetism after processing) ;

5) solid solution state non-magnetic; 

6) relative to 304 stainless steel, the price is higher. 

316L is molybdenum-containing stainless steel species, its performance is better than 310 and 304 stainless steel, so it is recognized by the market.

Application Scenario

You may ask, 316L stainless steel of these advantages in daily use can be reflected? Of course it can! In real life, we can often see this material being used in medical equipment, food processing equipment and chemical equipment. For example, in the medical field, some implanted equipment such as pacemakers, artificial joints, etc. often need to be exposed to bodily fluids, but 316L stainless steel plate is able to maintain stability in this environment, ensuring the health and safety of patients.

In addition, in the field of food processing, 316L stainless steel plate made of equipment can resist corrosion of acid and alkali substances in food, to ensure food hygiene and safety. In the chemical industry, equipment made of this material can withstand the erosion of various chemical substances, providing a reliable guarantee for production. Commonly used in pulp and paper equipment heat exchangers, dyeing equipment, film processing equipment, pipelines, coastal area building exterior materials, as well as high-grade watch bracelets, cases and so on. Equipment for ocean engineering, production equipment for chemicals, dyes, paper, oxalic acid, fertilizers, etc.; photographic, food industry, coastal area facilities, ropes, etc. .

In addition to this, 316L stainless steel has a wide range of applications in CNC machining because of its good corrosion resistance, mechanical properties and weldability. 316L stainless steel in CNC machining is used in applications such as parts manufacturing, chemical equipment, medical equipment, food processing equipment, and aerospace. In CNC machining, it is necessary to use the proper tools, cutting parameters and processes, while ensuring proper cutting lubricants and cooling systems to improve machining efficiency and tool life.
