Alloy 6150 Steel Suppliers - ThomasNetAlloy steel 6150 is used in the production of forged components of medium and large cross section, requiring high tensile strength and toughness, for automotive engineering and gear and engine construction, such as forged crankshafts, steering knuckles, connecting rods, spindles, intermediate gears, pump and gear shafts.
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. This grade has the highest hardness - 50HRC - among all the stainless steel grades with 12% chromium.

Small sections can be air cooled and larger sections oil quenched for maximum through hardness. Pre hardened and tempered 420 will also respond readily to nitriding achieving a typical surface hardness of over Rc65.
Grade 440C stainless steel is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance. Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys.
* It is very durable. Its low hardness makes it unlikely that a 420J2 blade will break, unless its design is structurally unsound. In short, it is a poor overall blade steel, that has little business being used for knives, outside of a dive knife. MOST, but not all, knives made from it are of inferior quality.

General Properties. Alloy 410 is the basic, general purpose martensitic stainless steel that is used for highly stressed parts and provides good corrosion resistance plus high strength and hardness.
content than Alloy 410 which is designed to optimize strength and hardness characteristics. It has good ductility it the annealed condition but is capable of being hardened up to Rockwell hardness 50 HRC, the highest hardness of the 12% chromium grades. Due to its hardening properties, Alloy 420 is not often welded, although it is possible.

He doesn't list the hardness of the carbon steel models, but I would guess in the 54-56 range. The carbon steel might not be as hard as the stainless, but in my experience it sharpens to a finer edge. Like Jacknife says, they're so inexpensive you can buy a couple of each and see which you prefer.

Alloy Steel 4150, also sold under the name AISI/SAE 4150, is a high-carbon alloy that includes chromium, manganese, and molybdenum. This tough steel alloy offers uniform strength, wear resistance, and great hardness. It is important to note that Alloy Steel 4150 must be heat-treated to be suitable for machining.
420HC is the predominate steel used by Buck on their knives made in the US. Paul Bos, IMO the Dean of heat treaters, worked out the best heat treatment for this steel years ago for Buck, with a Rockwell hardness in the upper 50's. I've found it to be a very good steel for most people.
Alloy steels are designated by AISI four-digit numbers. They comprise different kinds of steels having compositions exceeding the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va set for carbon steels. AISI 4150 alloy steel is a higher carbon variation of chromium, manganese, molybdenum 4100 low buy hardness s420j0

Stainless steels are called as high-alloy steels. Due to the presence of large amounts of chromium in the range of 4 to 30%, they have high corrosion resistance than other steels. Stainless steels are classified into martensitic, ferritic and austenitic based on their crystalline structure. However buy hardness s420j0
