Abstract
The invention relates to alloy used for a die casting mold. The alloy is composed of, by mass, 10-28 parts of chromium, 10-22 parts of nickel, 0.5-11 parts of manganese, 0.01-0.07 part of molybdenum, 50-80 parts of iron, and the balance impurities which are inevitable in a machining process. According to the technical scheme, the alloy has the technical effects that the performance parameters of hardness and yield strength under the high temperature are improved greatly.
Description
Technical field
The present invention relates to a kind of alloy for die casting, particularly relate to a kind of alloy of the mould for die casting stainless steel body.
Background technology
Existing die casting, in particular for the die casting of valve body, usual employing H13 steel, because it is high temperature resistant, wear-resisting, withstand voltage, anti-fatigue performance is inadequate, thus it can only the valve body of die casting as lower in fusing points such as aluminium alloys (lower than 700 DEG C), and die casting can not have the stainless steel of higher melt.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide a kind of there is hardness under high temperature, the alloy for die casting that yield strength performance perameter improves greatly.
For achieving the above object, the invention provides following technical scheme: a kind of alloy for die casting, is made up of the element chemistry formed as follows by mass fraction:
The chromium of 10-28 part,
The nickel of 10-22 part,
The manganese of 0.5-11 part,
The molybdenum of 0.01-0.07 part,
The iron of 50-80 part,
Surplus is unescapable impurity in the course of processing.
The present invention is set to further: be made up of the element chemistry formed as follows by mass fraction:
The chromium of 16-24 part,
The nickel of 13-17 part,
The manganese of 2-6 part,
The molybdenum of 0.02-0.05 part,
The iron of 60-70 part,
Surplus is unescapable impurity in the course of processing.
The present invention is set to further: be made up of the element chemistry formed as follows by mass fraction:
The chromium of 18 parts,
The nickel of 16 parts,
The manganese of 5 parts,
The molybdenum of 0.04 part,
The iron of 60 parts,
Surplus is unescapable impurity in the course of processing.
The alloy for die casting of technical solution of the present invention, has hardness under high temperature, a technique effect that yield strength performance perameter improves greatly, can be used in the stainless steel body that die casting has higher melt.
Below by way of specific embodiment, technical solution of the present invention and beneficial effect thereof are further described.
