Type S— is a highly alloyed austenitic stainless steel used for high temperature application. The excessive chromium and nickel content material give the steel wonderful oxidation resistance as well as high strength at excessive temperature. This grade can be very ductile, and has good weldability enabling its widespread usage in many applications. Due to the addition of molybdenum, grade 316 chrome steel is more corrosion resistant than similar alloys, such as 304 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.
Characteristics of Stainless Steel Sheet and Plate:
High corrosion resistance
High strength
High toughness and impact resistance
Temperature resistance
High workability, including machining, stamping, fabricating and welding
Smooth surface finish that can be easily clean
Stainless steel is made by adding 12% or extra chromium to the alloy. It is somewhat harder to work with and sharpen, but it has the advantage of corrosion resistance. Because of this, it will maintain an edge longer in moist situations. The time period surgical stainless-steel is meaningless, as a result of there is a couple of stainless steel used for surgical devices.
- This sort of stainless maintains its best corrosion resistance in the heat treated situation.
- 420 stainless steel is a martensitic larger carbon model of varieties 410 and 416 stainless that may be hardened by heat therapy.
- It has good ductility in the annealed situation however is able to being hardened as much as 50 RHC.
- Alro shares 420 Stainless Steel – a modification of 410 with the next carbon content material to increase hardness, enhance power and give higher put on resistance.
- It contains a minimum of 12 p.c chromium, adequate to provide 420 corrosion resistance properties.
What is the purest stainless steel?
Try the magnet test. If the magnet sticks it cannot be 316 and might be 304. If the magnet doesn’t stick it could be either 316 or cold worked 304, so heat the piece to about 800 °C, let air-cool and try again with magnet. If it sticks now its 304 SST.

Knife blades specified as being “440” can usually be assumed to be the lower hardness 440A grade. Under hardened situations, grade 420 steels are resistant to fresh water, alkalis, air, meals and mild acids. The steel grades with a clean surface finish have excellent performance. The corrosion resistance properties of grade 420 will are likely to fall beneath annealed circumstances. The corrosion resistance of grade 420 is decrease than that of the grade 430 Ferritic alloys with 17% chromium, grade 410 steels and other austenitic grades.
What is the hardest steel?
Heat Treatment Annealing – Grade 420 stainless steels can be heated at temperatures from 840 to 900°C, followed by slow furnace cooling at 600°C and then air-cooling. Process Anneal – Grade 420 can be annealed at 735 to 785°C and air-cooled.
The following Powder Metallurgy steels include very high 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 put on resistance.
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.
A cobalt-chromium-tungsten alloy named Talonite is similar to Stellite. Both alloys cannot be heat-treated and are non-magnetic. Titanium is thought primarily for making light-weight, high-power fasteners for aerospace use, however it is also used for knife blades. Titanium is favored for salt water diving due to its glorious corrosion resistance. Like Stellite and Talonite, titanium has a low Rockwell C hardness, however it has good wear resistance and requires diamond hones to sharpen.
420 series include several sorts with varied carbon content material between .15% and .forty% this steel grade is extensively used to make high finish razor blades, surgical scalpels and so forth. It obtains about fifty seven HRC after appropriate warmth treatment. The HC stands for “high carbon” and it may be dropped at a better hardness than common 420 and should not be mistaken for it. Buck Knives and Gerber Knives use 420HC extensively.420A and 420B are economical, highly corrosion resistant chrome steel grades.
