Steel 70ХЛ
Designation
Description
70ХЛ steel is used: for the manufacture of shaped castings of wear resistant mining parts and mining equipment.
Note
Steel chromium wear-resistant.
The steel has a high resistance to wear when exposed to high pressures or shock loads.
Standards
Chemical composition
Fe is the basis.
According to TU 4112-78269737-001-2005, deviations in the content of carbon and silicon in the range of +0.10% of each are allowed, according to the remaining elements - according to Table 5 of GOST 977. The list of other impurity elements and their mass fraction in the steel are indicated in the drawings castings. If there are no such indications in the drawing, then the control of the chemical composition is carried out only according to the elements specified in TU or GOST 977.
