In the situation of continuously rising prices of nickel, the stainless steel line containing low nickel content, low and stable prices offer attractive indeed. And Inox 201 is an appropriate choice, grade stainless steel is gaining more and more market, where stainless steel 304 and 301 stainless steel are mainly selected.
Inox 201 low and stable prices is due to use to replace the nickel Magan. This makes for much Inox 201 Inox 304 similar nature and have been superficially like Inox 304.
As a result, the stainless steel is a steel containing 11% chromium, precisely because it has created for itself stainless steel membrane protects against corrosion. Nickel also known as the key to bringing stability to the austenitic phase and excellent machining capabilities for Inox.
Inox 304 minimum nickel content of 8%. In forming Austenitc elements, there are many elements that can replace the nickel to create resistance to corrosion. Example: Chrom (this is the main element creating corrosion resistant stainless steel), manganese (also contributes to stable austenitic phase), Nitrogen also contributes to increased rigidity, Copper (Cu) also contributed to stable austenitic phase.
In Inox 201, people use Magan as key elements to replace nickel in a 2: 1. We can see under chemical composition as follows:
Inox 201 + 4.5% nickel and 7.1% manganese
Inox 304 + 8.1% nickel and 1% manganese
With ingredients like these have contributed to the cost of the raw material of stainless steel 201 down very low. This is the first advantage of 201.
Reliability and processing capabilities
Specific weight lower but Inox 201 Inox 201 reliability of greater than 10% compared with 304 Stainless Steel
Due to the elongation ability compared with 304 stainless steel, stainless steel should demonstrate similar characteristics as 304 during bending, shaping and laminated. But to some extent it still malleable stainless steel 304 and the flattening is more energy saving Inox 201 (this is due to the effects of manganese on Inox elements 201, 201 stainless steel hard work than Inox 304)
Resistance to corrosion
When comparing the chemical composition (TPHH) of 201 stainless steel and 304 stainless steel, we find chromium content of Inox 201 Inox 304 lower by about 2%. Because of this, 201 stainless steel corrosion resistant 304 stainless steel lower.
Pitting resistance is determined primarily by two elements chromium and Sulfur (S). Chrom help increase resistance to corrosion, whereas Sulfur reduces corrosion resistance. In the 2 Inox TPHH have the same ingredients Sulfur. So resistance to pitting of stainless steel 201 is lower than the 304 stainless steel.
304: 304 Stainless Steel
4Ni: 201 stainless steel (Inox 201 contains only about 4% nickel)
The results shown above after one test in 575 hours of salt water spray. Because of this, we see the Inox 201 is inconsistent with the maritime industry.
Applications of Stainless Steel 201
+ Kitchen equipment such as pan, pot => fit
+ Washer, Dishwasher => Not fit, so the possibility exists crevice corrosion)
+ Food Processing Equipment => Not recommended for areas with pH <3.
+ Chemical industry, oil and gas, nuclear energy => Can not
+ Decoration => fit
+ In the exterior location => Inappropriate, if used, must be maintained regularly.
