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.

420 Modified Annealed Stainless Steel Type 420 Stainless Steel, a modification of 410, has a better carbon content to extend hardness, enhance strength and give better put on resistance. This type maintains its greatest corrosion resistance within the heat treated condition. Several metal alloys have carbon amount shut or above three%. As ordinary these steels may be hardened to extremely excessive ranges, 65-67HRC. The following Powder Metallurgy steels include very high ranges of Chromium, which at 18–20% produces a metal matrix that’s extremely corrosion resistant.

It is much like Type 410, however has more energy and hardness. It can be hardened via heat treatment, which brings good ductility for steel fabricators as well as wonderful polishability. The steel grade 1.4021(also called ASTM 420 and SS2303) is a high tensile power martensitic stainless steel with good corrosion properties.

The HC stands for “high carbon” and it may be dropped at the next hardness than common 420 and should not be mistaken for it. Buck Knives and Gerber Knives use 420HC extensively.420A (420J1) and 420B ( 420J2 ) are economical, highly corrosion resistant stainless-steel grades. Knife producers use this materials in budget knives, additionally in diving knives as a result of its excessive resistance to corrosion. 440A is a relatively a low value, highly corrosion resistant stainless-steel. It could be very resistant to corrosion and is one of the commonest stainless alloys used for knife making.

Our stainless production range

• 420 sequence contain a number of types with numerous carbon content material between .15% and .40% this metal grade is broadly used to make excessive finish razor blades, surgical scalpels and so on.
• It obtains about fifty seven HRC after suitable heat treatment.
• 420HC ( 420C ) is a higher carbon content 420 stainless.
• The HC stands for “high carbon” and it can be brought to a better hardness than regular 420 and shouldn’t be mistaken for it.

Stainless Steel Properties

Must be cast and warmth treated at very excessive and actual temperatures. Can be used at very excessive hardness, corresponding to RC sixty four-66. Not alleged to be brittle, however high alloy steels usually are. Although typically used for aerospace bearings and other critical applications, its wonderful put on resistance and corrosion resistance makes it a superior choice for use in cutlery functions.

The as soon as ubiquitous American Buck Model one hundred ten Folding Hunter was made of 440C earlier than 1981. Knife blades specified as being “440” can typically be assumed to be the lower hardness 440A grade. BG-42 Slightly higher in carbon, chrome and moly than ATS-34.

This kind of stainless maintains its best corrosion resistance in the heat handled condition. 420 chrome steel is a martensitic higher carbon model of varieties 410 and 416 stainless that may be hardened by heat treatment. It incorporates a minimal of 12 percent chromium, enough to provide 420 corrosion resistance properties. The 420j2 stainless steel is a well-liked alternative for knife manufacturers. 420j2 stainless steel contains medium high quality carbon content material.

Stainless Steel Grades And Families: Explained

Similar to 4140, 6150 is a troublesome steel with good impact resistance that can be hardened to the mid-50s on the HRC scale. While a good material for swords or hatchets, it’s lower than best for most knives due to its restricted attainable hardness . Tolerates lower than ideal temperature management in forging and heat treating (As does 5160). Probably does not maintain an edge in addition to 1095, but is tough, and straightforward to sharpen. Type 420 Stainless Steel, also referred to as “surgical metal”, is an usually used high-carbon martensitic chrome steel.

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.
