440C stainless steel is a member of the 400 series of stainless steels. It has the highest carbon content among them. The standout properties of this type of steel are its hardness, mechanical strength and fatigue resistance. This combination of properties makes it useful in the production of cutting tools. Due to its high carbon content, it does not have outstanding corrosion resistance, but it can still be used for applications that require moderate corrosion resistance such as surgical instruments.
440C stainless steels typically have a composition of 78 – 83.1% iron, 16 – 18% chromium, 1 – 1.2% carbon, 1% (max) silicon, 1% (max) manganese, 0.8% molybdenum, 0.04% phosphorus and 0.02% sulphur. They have a martensitic grain structure, and they are primarily hardened through solid solution strengthening with chromium and precipitation hardening of molybdenum carbides

The material designated as “CuSn7ZnPb” is a type of bronze alloy commonly used for making bushings. It is very similar to the CuSn7ZnPb material you previously mentioned, and is generally known for its wear resistance, corrosion resistance, and machinability.
Characteristics of CuSn7ZnPb:Wear Resistance: High wear resistance due to the presence of tin.Corrosion Resistance: Good resistance to corrosion.Machinability: Good machinability due to the presence of lead.Strength: Moderate strength and hardness suitable for bushings and bearings.

Typical Composition:Copper (Cu): 83-87%Tin (Sn): 6-8%Zinc (Zn): 2-4%Lead (Pb): 1-3%
