We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.
Knife blades specified as being “440” can usually be assumed to be the decrease hardness 440A grade. The metals which might be characterized as metal are a diverse class of materials which might be an integral part of trendy society. Steel is an alloy that is made by combining iron with carbon in addition to different elements that present it with unmatched strength.
Stainless metal knives are normally made out of ferritic or martensitic stainless steels. In order to make knives that have respectable edge retention, the martensitic and ferritic grades of chrome steel have to have a excessive sufficient carbon levels to have the ability to attain high hardness. Grades corresponding to 420 and 440 are regularly used for knife making. 440A is a relatively a low price, extremely corrosion resistant stainless steel.
Due to its alloying concept, this steel offers extraordinarily high put on resistance and excessive corrosion resistance. Grade 440C stainless steels are high carbon steels, which attain the best hardness, wear resistance and power of all chrome steel grades after warmth remedy. These properties make this grade appropriate for purposes corresponding to valve elements and ball bearings. Grade 440A and 440B stainless steels, however, have similar properties – aside from a slightly decrease share of carbon in grade 440A. There are additionally precipitation-hardening stainless steels that have glorious corrosion resistance and hardenability properties.
The Leader In Small-quantity Metals
- 420 sequence include several varieties with various carbon content between .15% and .forty% this metal grade is extensively used to make high end razor blades, surgical scalpels etc.
- Other alloying elements contribute to grain refinement which improve blade strength and edge toughness and likewise permit for a finer, sharper edge.
- The stability of carbon and chromium content give it a excessive diploma of corrosion resistance and likewise spectacular physical traits of power and edge holding.
- Edge retention in precise chopping tests exceeded blades made of the 420 and 440 collection of stainless steels.

Our stainless production range
For AISI 440 chrome steel datasheet, heat treatment and equal chart, please see the tables below. Grade 440C stainless steel is capable of attaining, after warmth remedy, the best energy, hardness and wear resistance of all of the stainless alloys. Small AISI 440C metal sections may be air cooled and fairly massive sections oil quenched for max by way of hardness. PH – A Chromium/Nickel/Aluminum, precipitation-hardening, stainless-steel. The alloy is used for high-power applications requiring resistance to salt-water corrosion.
For extra info on chrome steel, discuss with our associated article that describes the categories and grades of those metals. 1055 steel is right on the border between a medium and a high carbon metal, with a carbon content material between 0.50%-zero.60% and with manganese between zero.60%-0.90% as the only other component.
The following Powder Metallurgy steels comprise very excessive levels of Chromium, which at 18–20% produces a steel matrix that’s extremely corrosion resistant. Developed for knife blades requiring good corrosion resistance and very excessive hardness for wonderful wear resistance. Chromium, molybdenum, vanadium, and tungsten are added for excellent sharpness and edge retention. Hardens and tempers to HRC, where it best balances edge holding and toughness.
One software metal grade that’s used as a knife materials is A2. While it can not attain hardness as high as some other device steels, it has glorious toughness. However, A2 might be subject to rust if care just isn’t taken. D2 is an alternative choice that has better corrosion resistance and edge retention than A2; nevertheless, this is at the expense of toughness.
We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
