Abstract

The invention relates to stainless steel. The stainless steel comprises, by weight, 0.04%-0.06% of carbon, 0.1%-0.12% of silicon, 0.05% of phosphorus or less, 7%-12% of manganese, 4%-8% of nickel, 6%-7% of chromium, 1%-3% of copper, 0.3%-0.5% of nitrogen, 0.03%-0.07% of titanium, and the balance ferrum. According to the stainless steel provided by the invention, higher hardness can be achieved through constituent combination, and thus the stainless steel has higher shock resistance.

Description

A kind of rustless steel
Technical field
The present invention relates to a kind of rustless steel, more particularly to a kind of high-hardness stainless steel.
Background technology
At present the blade of some domestic appliances, such as hay mover, its working environment complexity, are striking stone, wait firm During object, its blade will be damaged.
The content of the invention
The technical problem to be solved in the present invention is:Propose a kind of rustless steel of high rigidity.
The present invention is that the technical scheme for solving above-mentioned technical problem proposition is:A kind of rustless steel, by following weight material is compared Composition:Carbon 0.04% to 0.06%, silicon 0.1% to 0.12%, phosphorus 0.05% or less, manganese 7% to 12%, nickel 4% to 8%, chromium 6% to 7%, Copper 1% to 3%, nitrogen 0.3% to 0.5%, titanium 0.03% to 0.07%, balance of ferrum.
The rustless steel that the present invention is provided, it is into subassembly, there is provided more excellent hardness, so as to more shock resistance.
Specific embodiment
Embodiment
