APPLICATIONS/ ADVANTAGES | B7 studs are best suited for use in temperatures between 300° - 400° C. |
MATERIAL | Bolts shall be made from a grade B7 alloy which conforms to the following chemical composition requirements-- |
Carbon: 0.37-0.49%; Manganese: 0.65-1.10%; Phosphorus: 0.035% max; Sulfur: 0.040% max; Silicon: 0.15-0.35% ; Chromium: 0.75-1.20% ;Molybdenum: 0.15-0.25% | |
HEAT TREATMENT | Immediately after rolling or forging, the studs are cooled to a temperature below the cooling transformation stage. Parts are then hardened by heating to a temperature of 870°C and oil quenched then it is reheated to a minimum tempering temperature of 593°C and cooled in still air. |
HARDNESS | Rockwell C35 maximum |
YIELD STRENGTH | Studs 2.5” in diameter and smaller: 105,000 psi. minimum |
TENSILE STRENGTH | Studs 2.5” in diameter and smaller: 125,000 psi. minimum |
ELONGATION IN 4D | 16% minimum |
REDUCTION OF AREA | 50% minimum |
PLATING | Studs are typically provided plain without a secondary finish or as per requirement |
