T10 Tool Steel Properties T10 steel is a Chinese most common carbon tool steel with moderate toughness and low production cost. Tool Steel. The carbon tool steel usually is used to make sample measuring tools and cutting tools with small size and low-speed. And also is a good raw material for sample dies. It is the steel produced by adding proper alloy elements at the base of carbon steel to get higher properties.
Compare with carbon tool steel, its hardness, toughness and wear-resistance are raise. And its hardenability and hot hardness are raised dramatically.
And the steel grades are more, all kinds of characters can satisfy all kinds of needs of tools. So it was used to make measuring tools, molds and blade tools with big size, complex shape and high requirement of performance.
The carbon content of alloy tool steel is higher, many grades of them are high carbon steel. But the hot-work die steel is called medium carbon steel due to its high toughness and thermal conductivity.
The elements are added are wolfram, molybdenum, chromium, vanadium, manganese, silicon and so much more. Different levels for alloy steel because of the different total amount of alloy elements.
At the present time, most of the alloy tool steel is low alloy tool steel. The heat treatment of alloy tool steel usually uses the way of quenching and low-temperature tempering. But hot-work die steel needs great toughness, so must take the processing of hardening and tempering.
Vanadium, Columbium and Titanium are strengthening elements that are added to steel singly or in combination. In very small quantities they can have a very significant effect hence they are termed micro-alloys. Typical amounts are 0. The end result is superior formability and surface quality. Aluminum is used primarily as a deoxidizing agent in steelmaking, combining with oxygen in the steel to form aluminum oxides which can float out in the slag.
Typically 0. Aluminum acts as a grain refiner during hot rolling by combining with Nitrogen to produce aluminum-nitride precipitates. In downstream processing aluminum-nitride precipitates can be controlled to affect coil properties.
Nitrogen can enter steel as an impurity or as an intentional addition. Typically the residual levels are below 0. Boron is most commonly added to steel to increase its hardenability but in low carbon steels it can be added to tie up Nitrogen and help reduce the Yield Point Elongation thus minimizing coil breaks. At the same time, when processed appropriately, the product will have excellent formability.
For this purpose it is added in amounts up to approximately 0. As a residual in steel it is usually less than 0. D2 tool steel properties combine minimal distortion in heat treatment, high toughness and wear resistance at the expense of grindability and machinability compared to other grades. Its deep hardening ability helps it to resist chipping and cracking.
These characteristics along with price make D2 tool steel a high performance choice for applications requiring maximum dimensional stability in heat treatment, toughess, and wear resistance for longer life in long run, high production die applications. These applications include knife blades, thread rolling dies, lamination dies, blanking dies, forming dies, trimming dies, stamping dies, coining dies, drawing dies, extrusion dies, punches, punch plates, shear and slitter blades, gauges, knurling tools, rolls, mandrels and machine parts.
It combines excellent shock and abrasion resistance with good red hardness making it ideal for use in die casting. Most commonly used in plastic molds and die casting, its ability to withstand rapid cooling from high working temperatures also make it a prime choice for use in extrusion dies.
While designed to be a versatile hot work grade, H13 tool steel has been useful in cold work applications as well, particularly when extra toughness is desired but wear resistance is not important. Other applications include: trimming dies, extrusion dies, forging dies, die casting, forming punches, hot shear blades and mold dies. O1 tool steel is an oil hardening, cold work general purpose steel with easy machining properties and low hardening temperatures compared to other grades.
O1 provides good wear resistance and toughness sufficient for standard tool and die applications making it a suitable choice for tooling with good tool life and econimcal production. In situations that require greater size stability during hardening, A2 should be considered.
Some common applications include: bending dies, trimmer dies, perforators, broaches, blanking dies, forming dies, gages, cutting dies, bushings, forming rolls, knives, drawing dies, and embossing dies.
