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.

The as soon as ubiquitous American Buck Model a hundred and ten Folding Hunter was made of 440C earlier than 1981. Knife blades specified as being “440” can usually be assumed to be the lower hardness 440A grade.

1055 steel is correct on the border between a medium and a high carbon metal, with a carbon content between 0.50%-zero.60% and with manganese between zero.60%-0.90% as the one different part. The carbon content and lean alloy make this a shallow hardening steel with a quenched hardness between Rc relying on precise carbon content.

Type 304, the commonest grade of stainless-steel with 18% chromium, is immune to approximately 870 °C (1,600 °F). Other gases, similar to sulfur dioxide, hydrogen sulfide, carbon monoxide, chlorine, also attack stainless steel.

Our stainless production range

• Edge retention in precise cutting checks exceeded blades made of the 420 and 440 collection of stainless steels.
• Other alloying components contribute to grain refinement which increase blade power and edge toughness and likewise allow for a finer, sharper edge.
• The steadiness of carbon and chromium content give it a excessive diploma of corrosion resistance and also impressive physical characteristics of energy and edge holding.

Series—austentic Chromium-molybdenum Alloys

Knife producers use this materials in budget knives, also in diving knives because of its excessive resistance to corrosion. Another wear resistant materials is Stellite, a cobalt alloy with about 30% chromium, 3% or much less iron and 1 to 3% of other parts. Since it accommodates so little iron, it is technically not steel but a cobalt-chromium alloy. Stellite tests at a low Rockwell C hardness, about 38 to 40, nevertheless it accommodates tougher carbides that do the chopping and retain the edge. Stellite will tie or beat CPM-440V for edge-retention, but it is very tough to sharpen.

This steel in its unhardened or tempered state is simple to form by forging or grinding. It can then be warmth-handled to hardnesses appropriate for knives. High carbon steel takes a wonderful edge, nevertheless it has no corrosion resistance. The following Powder Metallurgy steels include very high levels of Chromium, which at 18–20% produces a metal matrix that is highly corrosion resistant.

Like Stellite and Talonite, titanium has a low Rockwell C hardness, however it has good put on resistance and requires diamond hones to sharpen. Most knives right now are created from some form of stainless steel. Stainless steel is made by adding 12% or more chromium to the alloy.

420 sequence include a number of sorts with varied carbon content between .15% and .40% this steel grade is broadly used to make excessive finish razor blades, surgical scalpels etc. It obtains about 57 HRC after appropriate heat remedy. 420HC ( 420C ) is a higher carbon content material 420 stainless. The HC stands for “excessive carbon” and it may be delivered to a higher hardness than common 420 and shouldn’t be mistaken for it. Buck Knives and Gerber Knives use 420HC extensively.420A (420J1) and 420B ( 420J2 ) are economical, extremely corrosion resistant stainless-steel grades.

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.
