1.3302 / S12-1-4 High Speed Steel
DIN 1.3302 / S12-1-4 high speed steel manufacturers and suppliers, supplied in round rods,square/flat bars,plates and sheets,produced as forged,rolled and cold drawn.
1.3302 tool steel is a Tungsten-Type high speed tool steel according to W-Nr standard,and S12-1-4 is as per DIN Germany standard.1.3302 is a high performance tool steel with durability and a good degree of toughness.The steel is used for special tools,such as tufting knives and loopers in the carpet industry as well as slot cutters or wood machining blades.Some steel bar applications using complicated tools require optimum dimensional stability at increased operational temperatures.
