فولاد ضد زنگ 440c عضوی از سری 400 فولادهای زنگ نزن است. در بین آنها بیشترین میزان کربن را دارد. از ویژگی های برجسته این نوع فولاد می توان به سختی، استحکام مکانیکی و مقاومت در برابر خستگی آن اشاره کرد.
The primary difference between the two steels is their chemical composition. 420HC is a high-carbon stainless steel that contains between 0.4% and 0.5% carbon, while 440C is a high-chromium stainless steel that contains between 0.95% and 1.2% carbon. The higher carbon content of 440C steel makes it harder and more abrasion-resistant, while …
Physical Property of 440, 440A, 440B, 440C, X90CrMoV18 high carbon martensitic stainless steel. Physical Properties for X90CrMoV18, 1.4112. softening annealing at a temperature of 780 - 840℃ with cooling in air or furnace. Hardening at 1000 - 1080 ℃ with cooling in water or oil. Tempering at a tempering of 100 - 200℃.
Reheat the metal to 400 - 800°F. This will leave you with a hardness in the range of Rockwell C55 - 56. Don't go over 800°F at this step, as studies show a decrease in toughness and corrosion resistance caused by higher-temperature tempering. Hold for at least two hours, plus 1 hour per inch of thickness over 2 inches.

Stainless steel is classified in three categories: martensitic, austenitic and ferritic. Martensitic – This very hard form of steel with a crystallite structure has three levels: 400A, 400B and 400C. The compound makeup of the favored 440C is generally 79.2% iron, 17% chromium, 1.1% carbon, 1% manganese, 1% silicon and .7% molybdenum.
Such as 440A, 440B, and 440C, which all have the same composition except they have different carbon contents. Each has ~17% chromium and an optional Mo addition along with 0.7% carbon (440A), 0.85% carbon (440B), or 1.05% carbon (440C). From what Microtech has told us I think the carbon change in M390MK is smaller than this example, …
AISI grade 440C stainless steel is pre-heated at 760°C (1400°F). Temperature can be increased up to 1038-1204°C (1900-2200°F). It should not be heated below 927°C (1700°F). It is then slowly cooled at room temperature and fully annealed. ASTM Grade Steel 440C is slightly cold workable using common practices.

It is thus odd to see people refer to 440C as some kind of low end/sub steel and S30V as some kind of high end steel when the differences are on the order of ~10%. Just imagine talking about differences in general in that way. Have you tried D2, that has an extremely coarse carbide structure inherently.

The Chinese steels are similar to AUS-8 and 440C. 8Cr13Mov was actually a poorly made attempt to replicate 440C steel. 440C is defined by a range of carbon content, not a single specific composition or maker. The range of carbon content in 8Cr13Mov is lower than that of 440C, so tends to have wear resistance more equivalent to AUS-8.

Possible alternative grades to 440 stainless steels Grade Reasons for choosing 440C 440A/B Slightly softer and more corrosion resistant grade needed
The answer to this question depends on the application. The main difference between 440A and 440C stainless steel is that 440A has a lower carbon content than 440C. This makes 440A more corrosion resistant, but it is also less hardenable. As a result, 440A is typically used in applications where corrosion resistance is more important than ...

4,437. Nov 3, 2015. #4. Böker is a reputable company, and can be expected to not screw around and lie. Like Knarfeg said, China has different designations for their steels. 440C has two common designations, either 9Cr or 10Cr, because 440C has a range of carbon levels, and it falls in the ranges of both designations.
It's because 440C is a tried, true, and proven standard that is here to stay. It's interesting to note that no one steel has come and wiped 440C off the field, replaced every application of 440C in industry, manufacturing, or the military industrial field. 440C, that old, boring high chromium, hardenable, wear-resistant martensitic steel is ...
Now it's your turn. Posted. I'd back up Brett on this- 440C is a far from optimal material for swordsmithing. 5160, L6, 1084 are all much better and far easier to forge, grind and heat treat. Recommended hot forming temp for 440C is about 1100C or about 2000F, and hardening temp about 1900F. Deep cherry will be far too cool, you likely need it ...
There are also many other steel companies that sell "standard" or lesser known steel grades like Aichi (AUS-8, AUS-10), Ahonest Changjiang (8Cr13MoV, 9Cr18MoV, 7Cr17), or Latrobe (BG42, 440C, D2). Steel Processors and Suppliers. The steel companies typically want to sell steel in large quantities to large customers.
440C. UNS #S44004. 440C stainless is a high-carbon chromium steel designed to provide stainless properties with maximum hardness. When heat-treated, it attains the highest hardness of any stainless steel at approximately Rockwell C 60. It has been used primarily as a bearing steel and is used in the hardened plus tempered condition.
440C should be annealed for maximum softness by thorough soaking at 1650°F for six hours followed by a furnace cool. This grade can be *cycle annealed by heating to 1600°F, holding two hours, cooling to 1300°F, and holding four hours. The steel may be cooled in air if desired. *Cycle (isothermal) annealing is most practical for applications ...
