Working with B23 Grade 14 Centrifugal Cast
Is B23 Grade 14 easy to machine?
Cuts very easily with sharp, high-rake tools and flood lubricant; use low pressure to avoid smearing, and control lead swarf/dust exposure.
Can B23 Grade 14 be welded?
Not arc-weldable; repair is by re-tinning and re-pouring the lining, or by babbitt build-up with a low-temperature torch.
Can B23 Grade 14 be formed, bent or molded?
Used as a cast lining only — pour at roughly 380–430 °C onto a clean, fluxed and tinned steel back; avoid overheating to limit antimony segregation and dross.
What surface finishes work on B23 Grade 14?
Bore and burnish to final clearance; no anodizing or plating — the running surface is left as machined, and lead handling/health rules apply.

B23 Grade 14 Centrifugal Cast — frequently asked
What is B23 Grade 14 Centrifugal Cast used for?
B23 Grade 14 Centrifugal Cast is typically used for light-duty bushings, general machinery bearings, low-load sleeve bearing linings, chill-cast bearing linings, centrifugally cast bearing liners and re-lined bearing shells. In short: cheapest B23 lead babbitt; light-load bearing lining; very easy to bore.
What is the yield strength of B23 Grade 14 Centrifugal Cast?
B23 Grade 14 Centrifugal Cast has a typical yield strength of 32 MPa (4.64 ksi) and a tensile strength of 70 MPa (10.2 ksi) — stronger than 73% of solder & low-melting alloy grades. Strength varies by condition: see the 3 listed tempers.
Is B23 Grade 14 Centrifugal Cast easy to machine?
Yes — machinability is rated excellent (92/100, better than 99% of solder & low-melting alloy grades). Cuts very easily with sharp, high-rake tools and flood lubricant; use low pressure to avoid smearing, and control lead swarf/dust exposure.
Can B23 Grade 14 Centrifugal Cast be welded?
Not readily — weldability is rated not recommended (10/100). Not arc-weldable; repair is by re-tinning and re-pouring the lining, or by babbitt build-up with a low-temperature torch.
What surface finishes work on B23 Grade 14 Centrifugal Cast?
Bore and burnish to final clearance; no anodizing or plating — the running surface is left as machined, and lead handling/health rules apply.
Can B23 Grade 14 Centrifugal Cast be formed, bent or molded?
Used as a cast lining only — pour at roughly 380–430 °C onto a clean, fluxed and tinned steel back; avoid overheating to limit antimony segregation and dross.
What is the maximum service temperature of B23 Grade 14 Centrifugal Cast?
B23 Grade 14 Centrifugal Cast is rated for continuous use to about 120°C (248 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
