Abstract

The invention discloses copper-manganese alloy steel. The copper-manganese alloy steel is prepared from the following ingredients in percentage by mass: 75-90% of iron, 10-15% of manganese, 1-3.5% of copper, 0.05-0.8% of phosphorus and the balance of unavoidable impurities, wherein the total content of the unavoidable impurities is not higher than 1.5%. The copper-manganese alloy steel disclosed by the invention has relatively high corrosion resistance and also has good deep drawability and abrasion resistance.

Description

A kind of cupromanganese steel

Technical field

The present invention relates to metal material field, particularly relate to a kind of cupromanganese steel.

Background technology

Society, rapid economic development, world economy has been stepped into the rapid growth of a new round, but resource consumes in a large number, make the price of metal also soar, for the development of world economy has brought negative impact, because use cheapness and the good alloy of performance to become a kind of trend.Wearing and tearing are many industrial sector ubiquities such as metallurgy, mine, machinery, electric power, coal, oil, traffic, military project and become a major reason that causes equipment failure or material damage, are also to cause one of problem that financial loss is maximum.Because the wear-resisting and shock resistance of the materials such as existing steel alloy is all not ideal enough, the financial loss that causes fret wear to cause is quite surprising.

Summary of the invention

The technical problem that the present invention mainly solves is to provide a kind of cupromanganese steel, has higher erosion resistance, has too good deep drawability and fastness to rubbing.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:

Provide a kind of cupromanganese steel to be grouped into by the one-tenth of following massfraction: iron: 75-90%; Manganese: 10-15%; Copper: 1-3.5%; Phosphorus: 0.05-0.8%; All the other are inevitable impurity, total amount≤1.5%.

In a more excellent example of the present invention, described cupromanganese steel is grouped into by the one-tenth of following massfraction: iron: 85-90%; Manganese: 10-12%; Copper: 1-3.5%; Phosphorus: 0.05-0.8%; Carbon: 0.5-0.8%; Silicon: 0.1-0.4%; Chromium: 0.1-0.3%.

In a more excellent example of the present invention, described cupromanganese steel is grouped into by the one-tenth of following massfraction: iron: 75-85%; Manganese: 12-15%; Copper: 2-3.5%; Phosphorus: 0.05-0.8%; Carbon: 0.5-0.8%; Silicon: 0.1-0.4%; Chromium: 0.1-0.3%.

The invention has the beneficial effects as follows: the invention provides a kind of cupromanganese steel, be grouped into by the one-tenth of following massfraction: iron: 75-90%; Manganese: 10-15%; Copper: 1-3.5%; Phosphorus: 0.05-0.8%; All the other are inevitable impurity, total amount≤1.5%, and this cupromanganese steel provided by the invention, have higher erosion resistance, has too good deep drawability and fastness to rubbing.

Embodiment

Below by specific embodiment, the present invention is conducted further description.

Embodiment 1: iron: 85-90%; Manganese: 10-12%; Copper: 1-3.5%; Phosphorus: 0.05-0.8%; Carbon: 0.5-0.8%; Silicon: 0.1-0.4%; Chromium: 0.1-0.3%.

Embodiment 2: iron: 75-85%; Manganese: 12-15%; Copper: 2-3.5%; Phosphorus: 0.05-0.8%; Carbon: 0.5-0.8%; Silicon: 0.1-0.4%; Chromium: 0.1-0.3%.

Embodiment 3: iron: 80-85%; Manganese: 10-15%; Copper: 2-3.5%; Phosphorus: 0.05-0.8%; Carbon: 0.5-0.8%; Silicon: 0.1-0.4%; Chromium: 0.1-0.3%.

The cupromanganese steel of the different components in three embodiment of the present invention, be grouped into by the one-tenth of following massfraction: iron: 75-90%; Manganese: 10-15%; Copper: 1-3.5%; Phosphorus: 0.05-0.8%; All the other are inevitable impurity, total amount≤1.5%, and this cupromanganese steel, have higher erosion resistance, has too good deep drawability and fastness to rubbing.

The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
