Standard API grade sucker rods are available in several steel grades each with its own set of properties and field of application:
Grade C: For light to medium load applications in wells that are sufficiently protected against corrosion.
Minimum yield: 414 MPa (60,000 psi)
Tensile range: 621-793 MPa (90,000-115,000 psi)
Grade K: For light to medium load applications in corrosive environments. However, to prolong service life, we recommend to sufficiently protect against corrosion.
Minimum yield: 414 MPa (60,000 psi)
Tensile range: 621-793 MPa (90,000-115,000 psi)
Grade D: For medium to heavy load applications in wells that are sufficiently protected against corrosion.
Minimum yield: 586 MPa (115,000 psi)
Tensile range: 793-965 MPa (115,000-140,000 psi)
Grade D special: Combines the properties of grade K and grade D carbon sucker rods. For medium to heavy load applications in corrosive environments. However, to prolong service life, we recommend to sufficiently protect against corrosion.
Minimum yield: 586 MPa (115,000 psi)
Tensile range: 793-965 MPa (115,000-140,000 psi)
