A27 Steel Chemical Composition Required 5 test pours to obtain correct composition 5 test heats = 663 pounds of steel 14 Heats total = 1848 lbs melted Composition Equivalent to Mild Steel 0.192% Carbon (C) 0.974% Manganese (Mn) 0.794% Silicon (Si)
Personal Protective Equipment • Hard hat with shield • Safety glasses • Aluminized jacket • Aluminized apron • Aluminized spats • (cover legs and ankles) • Aluminized gloves • Steel toed shoes
PPE Required For Grinding • Hard hat with shield • Ear plugs • Safety glasses • Flame resistant jacket • Steel toed shoes
Coordinate Measurement Machine Inspected prototype Made positioning fixture Visited “Stainless Foundry and Engineering” for consulting Measured each casting for tolerances
Measurement Points • Centerline – center hole to center hole • Distance between • hole and center • line • Degree of angle • from center of • hole to centerline
Tensile Bar Testing Made keel blocks Machined tensile bars Pulled tensile bars tests Tensile strength Yield strength Elongation Results All parts met specification
