Abstract
The invention relates to a gray cast iron alloy which comprises the following components by weight percent: 3.35-3.38% of carbon, 1.8-2.0% of silicon, 0.45-0.57% of manganese, 0.05-0.1% of chromium, 0.2-0.3% of molybdenum, 0.05-0.2% of vanadium, 0.5-0.8% of copper, 0.001-0.1% of niobium, 0.008-0.012% of titanium, 0.005-0.012% of nitrogen, less than 0.15% of phosphor and sulfur, less than 0.01% of aluminum and the balance of iron and inevitable impurities.
Description
Technical field
The present invention relates to the cast iron alloy material field, refer to specifically a kind of grey cast iron alloy with highly anti-fatigue intensity.
Background technology
Grey cast iron is because cost is relatively low, functional, so the wide range of using.But the compositing range of existing known grey cast iron is quite wide, yet as replenishing of existing performance, what need raising is fatigue strength, and the purposes of the existing grey cast iron of expansion.
Summary of the invention
The purpose of this invention is to provide a kind of grey cast iron, it has good processing characteristics and internal structure is arranged, and this cast iron alloy is compared the fatigue resistance with advantage with existing standard.
The present invention is achieved by the following technical solutions:
A kind of grey cast iron alloy, its composition of percentage composition comprises by weight: the carbon of 3.35-3.38%, the silicon of 1.8-2.0%, the manganese of 0.45-0.57%, the chromium of 0.05-0.1%, the molybdenum of 0.2-0.3%, the vanadium of 0.05-0.2%, the copper of 0.5-0.8%, 0.001-0.1% niobium, the titanium of 0.008-0.012%, the nitrogen of 0.005-0.012%, p and s less than 0.15%, the aluminium less than 0.01%, surplus is iron and inevitable impurity.
Described alloy is when refining, and chromium, titanium, v element will add at first, and then adds iron and carbon, is other element more afterwards.
The invention has the beneficial effects as follows,
By technical scheme of the present invention, have good processing characteristics and internal structure when realizing the fatigue resistance of this cast iron alloy.
Embodiment
Below describe technical scheme of the present invention in detail by embodiment.
In the following description, all per-cents of each element in the concrete grey cast iron alloy are weight percentage.
Alloy body in technical scheme of the present invention mainly is to form the grey cast iron with pearlitic texture, its carbon content is 3.35-3.38%, certain carbon content outside this scope also can realize the grey pearlitic texture, but when carbon content during in the scope of the technical program, pearlitic density is very low, the fracture of cast iron is white in color, when carbon content is higher than the scope of the technical program, pearlitic content can increase, but it is inhomogeneous that pearlitic texture can become, although can be by increasing other element such as chromium, copper, niobium, titanium, molybdenum etc., but the amount that needs adding is greater than the amount of the technical program, although can realize pearlitic even structure, can change the performance of cast iron and increase production cost.
The chromium that adds 0.05-01%, its effect is to form the stability structure with perlite/carbide, can realize the refined pearl-like body structure, although can be by adding better refined pearl-like body structure of more chromium, the chromium of 0.05-0.1% cooperates the formation optimum structure with other element.
The molybdenum that adds 0.2-0.3%, the vanadium of 0.05-0.2%, the titanium of 0.008-0.012%, the niobium of 0.001-0.1%, it has the nuclear core of refined pearl-like body structure and flake graphite structure, and molybdenum also has the effect of high temperatures pearlitic texture simultaneously.
The content of aluminium is lower than 0.01%, adds the manganese of 0.45-0.57% as the stablizer of pearlitic texture; The copper of 0.5-0.8% promotes perlite to form and stable and control pearlitic texture; The content of nitrogen is 0.005-0.012%, has the flake graphite of compression and promotes perlite to form; P and s in the alloy body is less than 0.15%, and surplus is iron and inevitable impurity.
Claims (2)
1. grey cast iron alloy, it is characterized in that: its composition of percentage composition comprises by weight: the carbon of 3.35-3.38%, the silicon of 1.8-2.0%, the manganese of 0.45-0.57%, the chromium of 0.05-0.1%, the molybdenum of 0.2-0.3%, the vanadium of 0.05-0.%, the copper of 0.5-0.8%, 0.001-0.1% niobium, the titanium of 0.008-0.012%, the nitrogen of 0.005-0.012%, p and s less than 0.15%, the aluminium less than 0.01%, surplus is iron and inevitable impurity.
2. a kind of grey cast iron alloy according to claim 1 is characterized in that: described alloy is when refining, and chromium, titanium, v element will add at first, and then adds iron and carbon, is other element more afterwards.
