Tool steel not stainless

Messaggio da Aldebaran »

Here, I'll explain 'properties' that a good razor or knife should also have regard to the type of steel usato.Elenchero' of the various types of steel commonly used for the forging of such instruments.
Property 'of steels and benefits:

Resistance to wear:

And 'capacity' to withstand abrasion, to influence and 'the amount' and the distribution of carbon within the steel.

Strength: It 'capacity' to suffer the weight of a load without deformation so permanente.Negli steel, strength and 'closely related to hardness.
Also note that the Rockwell hardness, and 'based on a measurement method that values the hardness of steel matrix, and is not based on quantita'di carbides and their distribution in the steel. This' allows us to understand why 'sometimes a steel "hard" will wear more' more easily than steel '"soft".

Hardness: E 'capacity' to withstand an impact without damage and chipping.

Resistance to stains: E 'capacity' to withstand ruggine.Gli stainless steels have better corrosion resistance than non-stainless, as the former have a higher percentage of free chromium than the latter.

Typically a steel razor but 'you wear more' easily than non-stainless, also because ', the former have a higher percentage of chromium atoms to free those carboniorispetto seconds.

Capacity 'of a cutting tool to hold the wire depends on all the characteristics listed above.

Capacity 'to better take the thread: Generally a razor coarse thread takes more' difficult of a fine-grained, the addition of vanadium improves this ability '.

Steels reach a good compromise on the features listed above:
Are Ats-34 (used by Mastro Livi) and S60V.

Given that already 'in another thread I treated alloys steels and their influence on the characteristics of the latter, will discuss' hours of various types of steel, classifying and explaining the peculiarities'.

Non-stainless steels:

Carbon steels can be hardened more 'easily than steel thanks to their better conductivity' termica.Inoltre can be hardened more 'times, even with differential temper, to give them a better equalization of carbon between the heart and the area and get him good strength and elasticity 'on the back and increased rigidity' on the coast.
As already 'mentioned, not a razor steel rusts, to varying degrees, much more' easily than steel.
In the system of the Convention AISI 10XX and the 'carbon steel alloy to some other element, for example, 50XX are chromium-carbon.

The SAE classification system, steels whose name starts with a letter (such as W2 and A2) are tool steels.
There 's a reference system, called ASMche based classification of steels according to their carbon content in percentage.
For example, the 1095 has a carbon content close to 0.95% in the matrix, and so on.


Q2: It 'a semi-steel with chromium content rather high, 12%, excellent wear resistance, hardness, we can forge good knives. [/ B]

Composition: http://translate.googleusercontent.com/ ... B74d0Lqotg


M2: It 's a high-speed steel'. Hardening takes very high temperatures, and 'slightly higher than the D2 with regard to wear resistance and hardness, but rusts easily.
Nerocagliostro confirms that its chemical structure and 'similar to Sheffield Steel.

Composition: http://translate.googleusercontent.com/ ... _Lekamk7g- kjtA38OAw

A2: A very good steel that you can 'toughen air, and' more 'hard M2 and D2, but with minor wear ressitenza. It can' be good for fighting knives.

Composition: http://translate.googleusercontent.com/ ... Zr9IoUWwxQ

O1: E 'a workable steel, holds well but the wire rusts very quickly. [/ B]

Composition: http://translate.googleusercontent.com/ ... NiIrApFKwA

W-2: The W-2 and W-1 differ only by the fact that the former has 0.2% vanadium content compared to the first that has this element.

Composition: http://translate.googleusercontent.com/ ... vGc_XB8WHQ


10XX Series: 1095,1084,1070,1060,1050 The steels are going well for cutlery, the 1095 and 'more' popular for knives, the 1050-1060 is used for swords.
Steels are rust easily and usually have the normal characteristics are without infamy and without praise.

0.170-6,50-100 B: are chromium-vanadio.Per rather, the number after the hyphen indicates the chromium content, the letter after the hyphen indicates the content of vanadium.

L-6: It 's a hard steel wire that holds well, but rusts easily, such as O1 and' without infamy and without praise is tempered easily.

5160: It 's a very hard steel, for large blades that need more' durezza.E 'a spring steel with addition of chromium to provide a better hardenability.' It has good wear resistance.

Composition:

52100: It has 1% carbon, compared with 0.60% of 5160.Raggiunge a good compromise between toughness' and wear resistance. It's good for the forging of hunting knives.

CPM10V: E 'to choose when you want to get maximum wear resistance has the hardness of D2.

CPM3V: Incredibly hard, good resistance to wear and stains.

Composition:

INFI: It has 0.50% carbon and contains azoto.Il result 'a stainless steel, not too resistant to stains.

Wascowear: steel with high vanadium content, out of production. [/ B]
