Knife Blade Materials

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.

It has good ductility it the annealed condition however is able to being hardened as much as Rockwell hardness 50 HRC, the very best hardness of the 12% chromium grades. Due to its hardening properties, Alloy 420 is not often welded, although it is potential. Martensitic stainless steels are designed for high hardness and generally other properties are to a point compromised. Its finest corrosion resistance is achieved when the steel is hardened and floor floor or polished.

However, proper heat treating must be carried out on high carbon steels. Tool steels are a very popular selection for making knives. Tool steels are, for essentially the most part, carbon steels which have extra alloying components that enhance their mechanical properties. These alloying components often enhance the metal’s corrosion resistance as properly, although to not the extent of a stainless-steel. PH – A Chromium/Nickel/Aluminum, precipitation-hardening, chrome steel.

Hardens and tempers to HRC, where it finest balances edge holding and toughness. Due to its alloying concept, this steel offers extraordinarily excessive wear resistance and excessive corrosion resistance. Stainless steel is another sort of knife-making metallic. The added benefit of using stainless steel is addition of chromium and other alloying parts that enhance corrosion resistance. Stainless metal knives are normally made out of ferritic or martensitic stainless steels.

Technique For our stainless

• The following Powder Metallurgy steels include very high ranges of Chromium, which at 18–20% produces a steel matrix that’s extremely corrosion resistant.
• Edge retention in actual slicing tests exceeded blades made of the 420 and 440 series of stainless steels.
• Other alloying parts contribute to grain refinement which improve blade power and edge toughness and also enable for a finer, sharper edge.
• The steadiness of carbon and chromium content material give it a high degree of corrosion resistance and also impressive physical characteristics of energy and edge holding.

Our stainless production range

It obtains about fifty seven HRC after appropriate heat remedy. 420HC ( 420C ) is a better carbon content 420 stainless.

There are additionally precipitation-hardening stainless steels that have glorious corrosion resistance and hardenability properties. These are sometimes used in functions the place corrosion is a large concern. 420 collection include several varieties with varied carbon content between .15% and .40% this steel grade is broadly used to make high end razor blades, surgical scalpels etc.

The stability of carbon and chromium content give it a high degree of corrosion resistance and in addition spectacular physical characteristics of strength and edge holding. Edge retention in actual cutting exams exceeded blades made from the 420 and 440 collection of stainless steels. Other alloying elements contribute to grain refinement which increase blade power and edge toughness and in addition enable for a finer, sharper edge.

The following Powder Metallurgy steels contain very excessive levels of Chromium, which at 18–20% produces a metal matrix that is extremely corrosion resistant. Developed for knife blades requiring good corrosion resistance and really high hardness for excellent wear resistance. Chromium, molybdenum, vanadium, and tungsten are added for wonderful sharpness and edge retention.

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.
