Which grade of stainless steel is better- 420 or 440? | Yahoo what is 420 modified steel? bladeforums

440 of any type is a higher grade of steel than 420. And there is a more complicated answer: It depends on what you want to do with it and what properties you want. All variants of 440 steel have higher carbon content than 420 which makes them hardenable to higher Rockwell hardness values which allows the blade to hold a better edge. What is "425 modified stainless"? | BladeForums what is 420 modified steel? bladeforums The COA that came with the knife says it's one of 100 made using a "vintage 1987 blade of 425 modified stainless steel."

Stainless Steel Grade 420J2 (UNS S42000)

Stainless steel grade 420J2 is known to possess good strength and reasonable impact resistant properties in hardened and tempered conditions when compared with 440 grades. The following sections will discuss in detail about stainless steel grade 420J2. Stainless Steel - Grade 420 (UNS S42000) Grade 420 stainless steel is a high-carbon steel with a minimum chromium content of 12%. Like any other stainless steel, grade 420 can also be hardened through heat treatment. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished, surface grounded or hardened. Speedy Metals Information for 420 Stainless Steel 420 stainless steel is a martensitic higher carbon version of types 410 and 416 stainless that can be hardened by heat treatment. It contains a minimum of 12 percent chromium, sufficient to give 420 corrosion resistance properties.
