Characteristics
1. A kind of cold work tool steel in widespread use, belonging to ledeburitic steel of high-carbon and high-chromium.
2. With quite good hardenability and abrasion resistance, but small quenching distortion.
3. With not good impact toughness, be liable to fracture and form inhomogenous eutectic carbides.
Application
1. Commonly used for manufacturing cold work moulds of excellent abrasion resistance with light shock loads, punch heads, cold cutting scissors, drill bushes, gauges, wire drawing dies, stamping dies, wire drawing sheets, drawing dies, thread rolling dies, etc.
2. Making cutting tools which is used for machining material of low hardness.
3. Used as plastic mould with good abrasion resistance and long service life.
