both have the same structures, but super austenitic stainless steels contain high amount of alloys elements
"Stainless steel" refers to a group of steels with similar compositions so since there are different compositions, there is not just a single boiling point that would apply to all stainless steels. A reasonable estimate that should be close enough for most purposes and most types of stainless steels would be about 5400 °F (approx. 3000 °C)
For example, steels as S30400 or S30403.
There is no "best" steel for knives as all of them have their advantages and disadvantages. Generally though, high carbon stainless steels would be better then the lower alloy non stainless steels. They perform just as good, but they have added corrision resistance. This is especially true of stainless steels such as Cpm S30v which has similar corrision resistance to 440c (the most corrision resistant steel that's useable for knives), yet is is tougher. .
Many types of stainless steels are used in chemical industry; the most important characteristic is the resistance to corrosion.
There are many stainless steels. These alloys are formulated partly for corrosion resistance and partly for physical properties (shear strength, hardness, high-temperature strength, resistance to metal fatigue, etc.). All of them are resistant to corrosion by water and air. Some especially corrosion-resistant stainless steels (such as 316 stainless) are also resistant to highly corrosive acids such as hydrofluoric acid; most are not.
Austenitic is not a type of steel, it is a description for steel and many stainless steels can be austenitic. Austenitic steels means that they contain 7% or more chromium or nickel as their major alloy elements and they have the highest corrosion resistance but are not heat treatable.
Ferritic and austenitic stainless steels are not heat treatable since "heat treatable" is taken to mean that martensite may be made to form with relative ease upon quenching austenite from an elevated temperature. For ferritic stainless steels, austenite does not form upon heating, and, therefore, the austenite-to-martensite transformation is not possible. For austenitic stainless steels, the austenite phase field extends to such low temperatures that the martensitic transformation does not occur.
While stainless steel is an alloy of steel, the primary difference between stainless steel and other steels is that the stainless steels have a high percentage (about 10% or even more) of the element chromium in them.
to use of low carbon austenitic stainless steels and stabiliser stainless steel will minimise the risk of
Duplex stainless steel are extremely corrosion resistant, work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades.

There are several types of stainless steel. However, austenitic (stainless) steels have chromium and nickel (sometimes manganese and nitrogen). Yes, they have steel also. However, the amount of actual "steel" is somewhere below 20%.
The metallurgical transfer motion behaviour during quenching is influenced by cooling rate, carbon concentrration , alloying elemnts and stress
A105 is a spec found on some types of carbon steel round bars. The term "ferritic" would not apply.Ferritic stainless steels contain larger amounts of Cr which stabilizes the ferritic phase. Ferritic stainless steels are highly corrosion resistant, but far less durable than austenitic grades and cannot be hardened by heat treatment. They contain between 10.5% and 27% chromium and very little nickel, if any. Typical applications may include appliances, automotive and architectural trim (i.e., decorative purposes), as the cheapest stainless steels are found in this family (type 409).
Aluminum is higher expansion - about 23 ppm/C, whereas steels range from 12ppm/C for alloy steel and carbon steel, 17 ppm/C for stainless 300 austenitic series, and 11 ppm/C for stainless 400 martensitic series
The major differences between 202 and 304 stainless steels are in the nickel and chromium contents. 202 has 16-18% chromium and 0.5-4.0% nickel, whilst 304 has 18-20% chromium and 8-10.5% nickel. There are other minor differences in the amount of carbon (0.08% in 304 and 0.12% in 202), manganese (2% in 304 and 5.5-7.5% in 202), as well as slight differences in the silicon, phosphorus and molybdenum contents. Both are austenitic steels and are essentially non-magnetic, but will become temporarily magnetic by working them. The manganese helps preserve the austenitic phase in the steels, as does the nickel. I can see an attraction in some people for using the 202 steel as it contains less nickel, and there is concern amongst some folk that they are sensitive to nickel.
It depends on the type of stainless steel you are referring to. Austenite and ferritic stainless is not heat treatable in which case carbon steel could be made far harder. However..martensitic stainless steels are heat treatable in which case they could be made harder depending on the alloy contents. Generally the more carbon a steel contains, the harder it can be made. Chromium; a key ingrediant in stainless steels, can also increase hardenability.
