What is 20Cr13 steel?
20Cr13 steel és low-carbon chromium alloy martensitic stainless steel, similar a 440C steel. La main difference between 20Cr13 and 440C steel that 20Cr13 steel has molt content chromium, making it easier to machine and polish.
What is the ASTM equivalent de X20Cr13?
1.4021 - X20Cr13 – AISI 420 – SAE 420 – ASTM F899.
What is 30Cr13 steel?
30Cr13 steel is a martensitic stainless steel. Martensitic stainless steel és el tipus de stainless steel whose mechanical properties can be adjusted through heat treatment. 30Cr13 steel ha higher strength, hardness, and hardenability than 410 (1Cr13) steel3. It ha good corrosion resistance to dilute nitric acid i weak organic acids at room temperature (700 degree), però les weldability no són les good a les 410 and 410J1 steel.
What is X30Cr13 stainless steel equivalent to?
X30Cr13 stainless steel is equivalent toAISI 420in the United States,ELS SEUS420J2in Japan,Z30Cr13in France, and3Cr13in Xina. It is also known by its European standard number,1.4028.

What is the difference between 2Cr13 and 3Cr13?
2Cr13 and 3Cr13 hi ha una mica difference in mechanical properties such as yield strength, tensile strength, and annealing hardness. After heat treatment, 3Cr13 és alt en hardness than 2Cr13, però la corrosió resistance is worse than 2Cr13.
What are the differences between 20Cr13 and 30Cr13 stainless steel?
El seu gran different és que el 30Cr13 té un gran carboni content, fent el maquinari però slightly less corrosion-resistent than 20Cr13, que és objecte de la màquina i ha fet carrosió resistance. 20Cr13. while 30Cr13 has a carbon content of 0.26–0.35%.
What are the differences between 14C28N and X30Cr13?
14C28N has a higher carbon and nitrogen content. Compared to X30Cr13, 14C28N offers significant better edge retention while maintaining excellent corrosion resistance. X30Cr13, porta a la seva hardness, mai slightly better toughness, però és inferior a 14C28N en most performance indicators.
Is 2Cr13 stainless steel good for knives?
Yes, el 2Cr13 estètica no és good for knives, especialment per kitchen i general-purpose use, du a to good corrosion resistance, hardness, and affordability. However, it can be brittle, particularment at high hardness levels, i mai no hold edge as well als higher-end steels.
