Merit. Variety of shapes and specifications.
By designing molds of different shapes, free-cutting steels with different cross-sectional shapes and tolerances of different specifications are cold-drawn. The angle can be at right angles or rounded.
High precision. High-quality carbide molds are used to ensure accurate and uniform tolerances.
The surface is smooth. The advanced cold extrusion process makes the surface of the easy-cutting steel product smooth and bright.
Mechanical properties. Tensile strength b (mpa) :(hot-rolled) 590 735;(High temperature tempered state after cold drawing) 590 785
Elongation δ5 ( hot rolled) 14;(Cold rolled) 17
Section shrinkage (hot-rolled) 20
Hardness. Hot rolled) 207HB; (cold drawn) 179 229HB
Delivery status. Delivered in hot-rolled or cold-drawn condition, the delivery status should be indicated in the contract. 15 is a free-cutting structural steel, good precision, easy to cut, greatly improve the service life of the tool, reduce the processing time.
It is S-P composite high-sulfur, low-silicon free-cutting steel. The machinability is significantly higher than that of Y12, and the production efficiency is 30 50% higher than that of Y12 steel, especially when tapping, the life of the tap is more than twice that of Y12.

There is only one standard for the density of the ceramic fiber module in the world, which is 220kg m, but in practical application, the density of the ceramic fiber module is set at 200-240kg m according to the furnace type, temperature, combustion medium, temperature rise requirements of the heat treatment furnace, because the ceramic fiber module is processed by the ceramic fiber blanket of the double-roller wire throwing process with today's more advanced technology, and the fiber length of the ceramic fiber blanket produced is between 80-130 mm. Therefore, the maximum density of the ceramic fiber module is 240kg m, beyond this density, the fiber will break a lot, and the fracture rate is as high as 48%. Therefore, after the actual verification of tens of thousands of industrial furnaces at home and abroad, the optimal density of ceramic fiber module is 220kg m. >>>More
The density of the stone mill is not large, which is determined by the network structure of the stone mill (the density of molecules in space is not large), so its density is not large, but because of its network structure (the molecules in the plane are closely arranged), its melting point is very high, even higher than that of diamond.
