Engineering Note: Weights shown reflect standard carbon steel (ASTM A105, density 7.85 g/cm³). For Stainless Steel (304L/316L, density 8.00 g/cm³) or Duplex 2205 (7.80 g/cm³), multiply nominal weight by the metallurgical density ratio. All Jayesh Forge production strictly maintains our 50 kg max piece limit.
