Maybe we hear a lot about AISI 440 steel. Do you know that it can be divided into three types? It contains 440A,440B,and 440C.
Classification of AISI 440 steel
Maybe we hear a lot about AISI 440 steel. It contains 440A,440B,and 440C. 440C is commonly used as making a knife. Otai special steel company provides 440 steel for our clients.
440C stainless steel is modern steel, known among all stainless steel alloys for its high corrosion resistance, abrasion resistance. It has good strength and hardness qualities, after heat treatment up to HRC60 hardness.
Application of AISI 440 steel
This steel can be used to make cutting tools, rolling bearings, valve seats, high-quality cutting tools. It is also used as surgical instruments, chisels, ball bearings . cutting tools such as barber blades, surgical blades, daggers, and blades are also made with 440 steel.
The grade of 440C is exactly the same as that of 440A and 440B.But it has a slightly higher carbon content. Although these three kinds of steel are the same grade of standard steel, in fact, 440C is more practical than A and B.
The 440C was the undisputed king of blade steel around the 1980s, a position that was not replaced by ats-34 until the 1990s. Even a novice blade maker can make a good blade with 440C if he can handle heat treatment and surface treatment well. And when well maintained, the blade of this material is excellent and durable.
Please note that 440A and 440B are alloy steels very similar to 440C and are often confused.But they are not suitable for the blade. The 440C is probably more suitable than any other alloy stainless steel for the cutting tool industry .and it is capable of a wide range of sizes and USES.
And now 440 steel families, there is a new type of modern steel known as 440V. Basically, this is an improvement of 440C steel. The steel has a similar hardness to the 440C. but it has greater corrosion resistance and machining capability.
