St Lawrence Steel - Shafting and Bar Products - Flexite®

Flexite is a tough, shock and fatigue resisting Chrome-Nickel-Moly alloy steel hot rolled, quenched and tempered bar. In the delivered quenched and tempered condition, it has the highest combination of tensile strength and ductility while maintaining comparably good machinability. Higher hardnesses attainable from 421-555 BHN. Flexite is quenched and tempered, stress relieved and machine straightened prior to shipment. This process insures proper grain structure alignment, removal of longitudinal stress factors and confines hardness range to within 2% variance in any bar or plate section. Most air-cooled alloy products, except tool steel, cannot meet these qualifications. As light reduction in hardness from surface to core is more desirable than “air hardened through hardness” since this provides much higher ductility and resistance to shock.
