Stainless Steel 440C Coil

Stainless Steel 440C Coil made primarily of iron, chromium, carbon and, to a lesser extent, molybdenum. It is part of the martensitic family of stainless steels known for their high strength, hardness and wear resistance. Stainless steel 440C coil is identified by its high carbon content, usually about 0.95-1.20%.

Chemical Composition of SS 440C coil

The composition of Stainless steel 440C coils  is crucial for understanding their properties and performance in various industrial applications.

Carbon0.95 to 1.20%Manganese (Maximum)1.00%
Phosphorus (Maximum)0.040%Sulfur (Maximum)0.030%
Silicon (Maximum)1.00%Chromium16.00 to 18.00%
Molybdenum (Maximum)0.75%IronBalance 

Thus, this table provides valuable insights into the chemical composition of these coils, highlighting their properties and suitability.

Mechanical Properties of Stainless steel 440C Coil

The table provides essential information for engineers and manufacturers to assess the integrity and durability of Stainless steel 440C coil  in demanding environments.

Yield Strength 0.2% Proof (Mpa)448
Tensile Strength (Mpa)75
Elongation (% in 50mm)14
Hardness (HB)269 max

Thus, this valuable data on the Stainless steel 440C coils’ strength, ductility, and resilience is crucial for ensuring the reliability and longevity.

Features of Stainless Steel 440C Coil

Some features of stainless steel 440C coil are:

  • High Hardness: Stainless steel 440C coil has very high hardness making it ideal for use where there’s need for wear resistance as well as edge retention.
  • Excellent Wear Resistance: Stainless steel 440C coil withstands abrasion and friction without significant loss in material through good wear resistance.
  • Good Corrosion Resistance: Stainless steel 440C coil shows good corrosion resistance, especially in mildly corrosive environments.
  • High Strength: SS 440C coil is characterized by high strength and toughness which gives provision to mechanical properties.
  • Edge Retention: The relative sharpness or dullness that remains after usage makes SS 440 coil suitable for cutting tools such as blades that require long-term sharpness, also known as edge retention.
  • Heat Resistance: This implies that at elevated temperatures; 440C stainless steel coil  retains most of its mechanical properties since heat does not affect all materials equally hence they have different heat resistivity levels.
  • Magnetic Properties: It can be an advantage when some applications require magnetic properties because stainless steel 440C coil  is magnetically labeled due to its nature.
  • Ease Of Machining: Even though stainless steel 440C coil  includes many elements, the right method plus tools can result in the fabrication of complex shapes or components using appropriate machining techniques.

Overall, stainless steel 440C offers a combination of unique attributes that make it suitable for use in various industries.

Application of Stainless Steel 440C Coil

The combination of different properties makes stainless steel 440C coil applicable in various industries and sectors. Some common applications include:

  • Cutlery: High-quality kitchen knives, chef knives and other cutlery items are made with 440C stainless steel coils.
  • Bearings and Ball Valves: Bearings, ball valves as well as other precision parts meant for use on machinery and equipment that are manufactured with stainless steel 440C coil.
  • Surgical Instruments: In the medical sector, surgical instruments such as scalpels, forceps or scissors are fabricated from stainless steel 440C coil.
  • Industrial Blades and Cutting Tools: Industrial blades, cutting tools and machine knives needed in various manufacturing processes are made using stainless steel 440C coil.
  • Aerospace Components: Turbine blades, bearings and structural elements among others need to be produced using SS 440C coil.
  • Oil and Gas Equipment: Drilling equipment valve components, among other things, like downhole tools for the oil & gas industry, where stainless steel 440C coil is used extensively in its manufacture.
  • Sporting Goods: For example, for hunting knives, fishing tools, outdoor gear, etc Stainless Steel 440C wire is used in these sports appliances.
  • Tooling and Die Making : Toolmaking in general involves making a wide variety of molds, dies as well as punches for use within manufacturing processes which can be constructed from Stainless Steel 440C coil .

SS 440C coils have multiple applications due to its versatility under extreme conditions needing high performance or durability.
