OTAI SPECIAL STEEL is A8 steel stockholders and suppliers from china. more 16 years experience in AISI A8 tool steel round bar, flat bar and plate supply.
AISI A8 is a high quality Cold work tool steel, It belong to the high quality medium carbon high Cr, Mo, V alloy tool steel. Oil Quenched & Tempered Hardenss is 28-34 HRc. AISI A8 steel Annealing delivery hardenss less than 250HB. Cold work tool steel A8 an excellent choose for applications that require higher toughness than that of the high-carbon, high-chromium steels such as D2 tool steel & better wear resistance than that of shock-resisting steels such as S7 steel.
A8 tool steel properties as below
Form of Supply
AISI A8 tool steel, we can supply the round bar, steel flat bar, plate, hexagonal steel bar and steel square block. AISI A8 steel Round bar can be sawn to your required lengths as one offs or multiple cut pieces. A8 steel Rectangular pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar can be supplied, providing a quality precision finished bar to tight tolerances.
Tempering of A8 tool steel
Tempering of A8 steels is performed at 148-315°C (300-600°F), Double tempering is recommended for tempering temperatures of 900°F and higher.Soak well at the selected temperature and soak for at least one hour per 25mm of total thickness. Below only for reference.
Applications
A8 steels are mainly used for slitters, die shapes.
Typical applications include Punches, drift pins, pneumatic tools, chuck jaws, hammers, hot rolls, and hot and cold shear knives, etc.
