Working with B23 Grade 13 STATIC-CAST
Is B23 Grade 13 easy to machine?
Very easy to bore and scrape with sharp, high-rake tools and generous chip clearance; use light cuts and coolant to avoid smearing and heat build-up.
Can B23 Grade 13 be welded?
Not fusion-weldable in the structural sense; repairs are made by re-melting/re-pouring the lining or by lead-burning with matching filler at low heat.
Can B23 Grade 13 be formed, bent or molded?
Poured at roughly 420–480 °C into tinned, preheated shells; keep the melt stirred to avoid antimony-rich segregation and chill quickly for a fine structure.
What surface finishes work on B23 Grade 13?
Bore, then diamond-burnish or fine-scrape to the oil-film clearance; no plating or anodizing — protect stock from acidic oils and observe lead-handling/RoHS restrictions.

B23 Grade 13 STATIC-CAST — frequently asked
What is B23 Grade 13 STATIC-CAST used for?
B23 Grade 13 STATIC-CAST is typically used for industrial bearing shells, pump bearings and rolling mill bearings. In short: hardest low-tin lead babbitt; tin-lean substitute for Grade 7/8; free-machining bearing lining.
What is the yield strength of B23 Grade 13 STATIC-CAST?
B23 Grade 13 STATIC-CAST has a typical yield strength of 28 MPa (4.06 ksi) and a tensile strength of 62 MPa (8.99 ksi) — stronger than 51% of solder & low-melting alloy grades. Strength varies by condition: see the 2 listed tempers.
Is B23 Grade 13 STATIC-CAST easy to machine?
Yes — machinability is rated very good (80/100, better than 85% of solder & low-melting alloy grades). Very easy to bore and scrape with sharp, high-rake tools and generous chip clearance; use light cuts and coolant to avoid smearing and heat build-up.
Can B23 Grade 13 STATIC-CAST be welded?
Not readily — weldability is rated poor (15/100). Not fusion-weldable in the structural sense; repairs are made by re-melting/re-pouring the lining or by lead-burning with matching filler at low heat.
What surface finishes work on B23 Grade 13 STATIC-CAST?
Bore, then diamond-burnish or fine-scrape to the oil-film clearance; no plating or anodizing — protect stock from acidic oils and observe lead-handling/RoHS restrictions.
Can B23 Grade 13 STATIC-CAST be formed, bent or molded?
Poured at roughly 420–480 °C into tinned, preheated shells; keep the melt stirred to avoid antimony-rich segregation and chill quickly for a fine structure.
What is the maximum service temperature of B23 Grade 13 STATIC-CAST?
B23 Grade 13 STATIC-CAST is rated for continuous use to about 115°C (239 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
