What is 440C Stainless Steel?
440C stainless steel is a high-carbon martensitic stainless steel that offers a combination of high strength, hardness, wear resistance, and corrosion resistance. It is heat treatable and can be hardened to a Rockwell hardness of 60 HRC.
What is the composition of 440C stainless steel?
440C stainless steel typically contains the following elements:
Carbon: 0.95 - 1.20%
Chromium: 16.0 - 18.0%
Molybdenum: 0.75 - 1.00%
Nickel: Less than or equal to 1.00%
Silicon: Less than or equal to 1.00%
Manganese: Less than or equal to 1.00%
Phosphorus: Less than or equal to 0.040%
Sulfur: Less than or equal to 0.030%
What are the properties of 440C stainless steel?
440C stainless steel exhibits the following properties:
440C stainless steel can be heat treated to achieve high strength and hardness, making it suitable for demanding applications.
The high carbon content and martensitic structure of 440C stainless steel contribute to its good wear resistance.
The presence of chromium in 440C stainless steel provides it with good corrosion resistance.
440C stainless steel can be used at temperatures up to 570 degree (1058 degree F).
What are the applications of 440C stainless steel?
440C stainless steel is used in various applications, including:
440C stainless steel is commonly used for making knives and cutting tools due to its high strength, hardness, and wear resistance.
440C stainless steel is often used for molds and dies because of its high strength, hardness, and wear resistance.
440C stainless steel is frequently used for bearings due to its high strength, hardness, and wear resistance.
440C stainless steel can also be used in other applications that require high performance, such as springs, valves, and pumps.
How is 440C stainless steel heat treated?
440C stainless steel is typically heat treated in three stages:
The steel is heated to a high temperature (typically 1050 degree - 1150 degree ) and then slowly cooled to room temperature. This process softens the steel and makes it easier to machine.
The steel is heated to a high temperature (typically 1020 degree - 1080 degree ) and then quenched in oil or water. This process increases the steel's strength and hardness.
The steel is heated to a lower temperature (typically 175 degree - 375 degree ) and then cooled to room temperature. This process relieves some of the stresses introduced during hardening and improves the steel's toughness.
What are the advantages and disadvantages of 440C stainless steel?
Where can I buy 440C stainless steel?
440C stainless steel can be purchased from a variety of suppliers, including metal distributors, online retailers, and specialty steel suppliers.
