420HC Stainless Steel vs. 440C Stainless Steel for Knife

440C stainless steel is commonly used for knife blades because it has the ability to withstand staining from many acidity foods and fruits due to its great strength and durability. This high chromium stainless steel exemplifies the perfect balance of resistance to deterioration and strength. 440C stainless steel takes a good edge and is easy to 440 Stainless Steel - Continental Steel & Tube Company

  • Common ApplicationsMachinability and FormabilityChemical CompositionBasic Properties of 440 Stainless SteelComparing Types of 440 Stainless SteelLearn MoreBesides being used for cutlery and razorblades, 440 stainless steel is also used for small applications such as dental and surgical instruments. Its high heat and corrosion resistance make it ideal for engine parts like rolling bearings and valve seats, and with superior hardness and abrasion resistance, its particularly well suited to manufacturing precision pivot pins and rollers.Stainless Steel 440A Sheet, SS 440A Hot Rolled Sheets Stainless Steel Grade 440A should be soaking at moderate temperatures before annealing. Conversely, for hardening, the substance must be gently heated to 760 degrees Celsius, then immersed at 1010 ° Celsius, and then cooled with air or oil. Our 440A Sheets are utilized in a wide variety of industrial purposes including turbine components

    440A vs 440C BladeForums

    Oct 14, 2011 · To be clear, 440A is a solid knife steel and in fact has several advantages over 440C; it is tougher, has a higher edge stability (much), and is more corrosion resistant. But in practice it tends to be used on cheap knives and gets low end heat treatment and thus the performance is often very low. 440A vs 440C vs other choices for knife - FinishingJun 12, 2009 · There is no catchall perfect steel. 440A is good for kitchen knives, but nfg for survival knives. The stain resistance and ease of sharping are the primary reasons they chose 440A. With the forever guarantee the company carries it's important they have an easily sharpened steel. AISI SS 440 Stainless Steel 440C 440A 440B Material Dec 14, 2019 · SS 440A, 440B and 440C stainless steel are AISI and ASTM standard high carbon high chromium martensitic stainless steel, SS440 has high strength, good hardness, corrosion resistance, wear resistance and high temperature dimensional stability. For AISI 440 stainless steel datasheet, heat treatment and equivalent chart, please see the tables below.

    Types 410, 420, 425 Mod, and 440A

    heat treatment is necessary. The stainless steel alloys shown in the table on Page 3 were heated as sheet samples for 60 minutes per inch of thickness at 1800°F (982°C) for Type 410 and at 1900°F (1038°C) for Types 420, 425 Modified, and 440A, and then air cooled to room temperature. The as-quenched structure of fresh martensite must be What is 440C Steel? Black Iron Canada440A:this is a hardenable stainless steel alloy, hardenable to a higher hardness than 420 series stainless steel (which are only hardenable to 52 HRC!). 440A has good corrosion resistance, and is used in less expensive bearings and in harder surgical tools (rare).
