Harnessing the Strength and Machinability of X12CrMoS17 Steel Grade

X12CrMoS17 is a stainless steel grade that exhibits a combination of high strength and machinability. Its mechanical properties and chemical composition contribute to its overall performance.

Mechanical properties:
1. Tensile strength: X12CrMoS17 steel grade has a high tensile strength, typically ranging from 600 to 900 MPa. This property allows the steel to withstand various external forces without deformation or failure.
2. Yield strength: The yield strength of X12CrMoS17 steel grade is typically around 400 to 600 MPa. This property indicates the maximum stress that the steel can withstand before permanent deformation occurs.
3. Elongation: X12CrMoS17 steel grade typically exhibits an elongation of 10% – 25%. This property signifies the steel’s ability to deform and stretch before breaking.
4. Hardness: The hardness of X12CrMoS17 steel grade typically ranges from 200 to 250 HB. This property reflects the steel’s resistance to deformation and abrasion.

Chemical composition:
1. Carbon (C): X12CrMoS17 steel grade generally contains a carbon content ranging from 0.08% to 0.15%. Carbon contributes to the steel’s strength and hardness.
2. Chromium (Cr): With a typical content of 16% to 18%, chromium enhances the steel’s corrosion resistance and hardness.
3. Molybdenum (Mo): The molybdenum content in X12CrMoS17 steel grade is typically around 0.8% to 1.1%. It improves the steel’s high-temperature strength and resistance to corrosion.
4. Sulphur (S): X12CrMoS17 steel grade contains sulfur in the range of 0.15% to 0.35%. The presence of sulfur increases the machinability of the steel.
5. Silicon (Si): X12CrMoS17 steel grade generally contains a silicon content between 1% and 2%. Silicon improves the steel’s resistance to oxidation and enhances its mechanical properties.
6. Phosphorus (P): The phosphorus content in X12CrMoS17 steel grade is typically kept below 0.04%. Phosphorus can have detrimental effects on the steel’s properties, so its concentration is controlled.

Overall, the mechanical properties of high tensile strength, good yield strength, elongation, and hardness, combined with the chemical composition comprising carbon, chromium, molybdenum, sulfur, silicon, and controlled phosphorus content, makes X12CrMoS17 steel grade a suitable choice for applications requiring strength and machinability.
