Abstract

The invention belongs to the field of metallurgy and specifically relates to boron-containing ultrahigh-manganese steel. The boron-containing ultrahigh-manganese steel comprises the following chemical components: 1.1wt%-1.4wt% of C, 0.3wt%-1.0wt% of Si, 16wt%-19wt% of Mn, 5.0wt%-25.0wt% of Cr, 4.0wt%-6.0wt% of Ni, 0.001wt%-0.1wt% of B, not more than 0.04wt% of P, not more than 0.1wt% of S and the balance of Fe. According to the boron-containing ultrahigh-manganese steel provided by the invention, by adding the boron, carbide particles in a structure are refined and the distribution is more uniformly dispersed. Under the condition of low impact abrasive wear, the relative wear resistance of the ultrahigh-manganese steel with the boron content of 0.0040% achieves 1.98.

Description

A kind of ultra-high manganese steel of boracic
Technical field
The invention belongs to field of metallurgy, be specifically related to a kind of ultra-high manganese steel of boracic.
Background technology
Ultra-high manganese steel is as high-abrasive material, and at opposing thump, bear abrasive wear or the cutter skiving damage aspect of large pressure, the wear resistance of its excellence is that other materials is incomparable.This Work Hardening Characteristic of ultra-high manganese steel makes it be widely used in for a long time in the mechanized equipments such as metallurgy, mine, building materials, railway, electric power, coal.
Along with the development of modern industry, its wear-resistant accessory weighs several tons to tens tons, and net thickness is all at more than 10cm, and conventional ultra high manganese steel is difficult to meet application demand.Ultra-high manganese steel, under low shock load or low-stress, does not reach work hardening capacity, and the wear resistance of ultra-high manganese steel can not get good performance.Therefore, people add in ultra-high manganese steel micro-in done large quantifier elimination, to seek to improve further the mechanical property of ultra-high manganese steel, work hardening capacity and wear resistance.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of ultra-high manganese steel of boracic, overcome that existing ultra-high manganese steel exists under low shock load or low-stress, do not reach work hardening capacity, wear resistance can not get the defect better played.
In order to solve the problem, technical scheme provided by the invention:
A ultra-high manganese steel for boracic, is characterized in that the chemical composition of the ultra-high manganese steel of boracic is: C1.1 ~ 1.4wt%, Si0.3 ~ 1.0wt%, Mn16 ~ 19wt%, Cr5.0 ~ 25.0wt%, Ni4.0 ~ 6.0wt%, B0.001 ~ 0.1wt%, P≤0.04wt%, S≤0.1wt%, surplus is Fe.
A kind of ultra-high manganese steel of boracic, it is characterized in that the chemical composition of the ultra-high manganese steel of boracic is: C1.1 ~ 1.4wt%, Si0.3 ~ 1.0wt%, Mn16 ~ 19wt%, Cr5.0 ~ 25.0wt%, Ni4.0 ~ 6.0wt%, B0.012 ~ 0.23wt%, P≤0.04wt%, S≤0.1wt%, surplus is Fe.
The ultra-high manganese steel Boron contents of described boracic is 0.006wt%.
The ultra-high manganese steel Boron contents of described boracic is 0.003wt%.
The ultra-high manganese steel of a kind of boracic as claimed in claim 1 or 2 or 3 or 4, also containing rare earth element Ga in this steel, its content is 0.001 ~ 0.18wt%.
Advantageous Effects:
(1) boron add the carbide particle refinement made in tissue, and the even dispersion more that distributes.
(2) under low condition of impact abrasive, Boron contents is the ultra-high manganese steel of 0.0040%, and relative wear resistance reaches 1.98.
(3), when Boron contents is 0.0020%, after 1100 DEG C of water-tenacity treatment, over-all properties is better, and now HB=215, ak=191J/cm2, relative wear resistance is 1.46.
