This alloy is a High Speed, tungsten type tool steel. It is a deep hardening alloy capable of Rockwell C 64 hardness.
Applications: Generally used as cutting tools, broaches and cold extrusion punches, turning and milling cutters for roughing work.
Heat to 820-850°C, cool slowly in furnace to 550°C then air. This will produce the maximum Brinell Hardness of 265.
Stress relieving to remove machining stresses should be carried out by heating to 600-650oC, holding for one hour at heat, followed by aircooling. This operation is performed to reduce distortion during heat treatment.

Frequently Asked Question:
1 Q: What's the payment term?
A:T/T 30% for downpayment,then T/T balance on the actual weight of ready for shipment products on the basis of the Seller's account.
2 Q: How to ensure your products is qualified?
A: The Quantity and weight of product are certified by the seller’s Inspection Certificate and the quality is certified by the Mill Taste Certificate agreed form.
Q: How to confirm the Acceptance of Goods and Quality Control?
A:Once the manufacturing of a batch is complete, two samples will be acquired at random by the buyer’s representatives for testing at independent
labs. One sample will be sent to a lab in Seller’s country and the other sample to a lab in buyer’s country.
