It additionally is often used for dental and surgical equipment. 1055 steel is true on the border between a medium and a excessive carbon steel, with a carbon content material between 0.50%-0.60% and with manganese between 0.60%-0.90% as the one other element. The carbon content material and lean alloy make this a shallow hardening steel with a quenched hardness between Rc depending on precise carbon content.


We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include 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 toughness and resistance
Temperature resistance
High workability, including machining, stamping, fabricating and welding
Smooth surface finish that can be easily clean

All steels comprise certain different components in managed amounts, like Manganese, Sulfur, Silicon, and Phosphorus. If nothing else is present, the steel is known as plain carbon steel. Steels used for knife blades are enhanced with additional parts and are called alloy steels. It is these additions that give different types of steel their particular properties. Alloy steels which have additions to make them corrosion-resistant are labeled stainless steels, and these are the steels most incessantly used in making knife blades.

IS 440c stainless steel good for knives?

440C should be annealed for maximum softness by thorough soaking at 1650°F for six hours followed by a furnace cool. This grade can be *cycle annealed by heating to 1600°F, holding two hours, cooling to 1300°F, and holding four hours. The steel may be cooled in air if desired.

Many bladesmiths, because of an incapability to work with it, call it an “inferior” steel. Most metallurgists contemplate 440C to be normal by which all different stainless steels are measured. In turn, some of the most celebrated knives all through fashionable historical past are made with this glorious materials. The added good thing using stainless steel is addition of chromium and different alloying components that improve corrosion resistance.

Stainless steel, first called “rustless steel,” is a combination of iron, chromium, carbon and a number of other different metals. Metallurgists have been seeking a greater steel for gun barrels to be able to over come issues brought on by fast overheating when the weapons have been fired shortly numerous times. In doing so, they accidently discovered the optimum material for knife blades, chrome steel.

  • The larger the carbon, the more put on resistant, yet decrease corrosion resistance.
  • The greater the chromium content material, the higher the corrosion resistance, however lower the damage resistance.
  • As a end result, 440C is a bit more expensive and takes a backseat to different steels.
  • The key to stainless-steel is the steadiness between carbon and chromium.

The key to stainless steel is the balance between carbon and chromium. The greater the carbon, the more put on resistant, but lower corrosion resistance. The greater the chromium content material, the higher the corrosion resistance, but lower the wear resistance. As a result, 440C is a little more costly and takes a backseat to different steels.

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.

One software steel grade that’s used as a knife material is A2. While it cannot attain hardness as excessive as another device steels, it has wonderful toughness. However, A2 could be topic to rust if care is not taken.

D2 is an alternative choice that has higher corrosion resistance and edge retention than A2; nonetheless, this is on the expense of toughness. M2 is a software steel that’s excellent at retaining a knife edge, but it can be too brittle for some functions. Tool steels are a very popular choice for making knives.

440C reveals finest corrosion resistance within the hardened situation. It has wonderful resistance to wear and abrasion and is magnetic in all circumstances. It develops the very best hardness of the stainless steels.

What is the best metal for a knife blade?

Grade 440C stainless steel is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance.
