Abstract
The invention discloses a metal alloy material. Calculated according to percentage by weight, the metal alloy material consists of the following components: 0.40 to 1.00 percent of carbon, 0.60 to 2.00 percent of silicon, 2.00 to 4.00 percent of manganese, 0.10 to 0.50 percent of chromium, 0.08 to 0.60 percent of titanium, 0.01 to 0.20 percent of rare earth and the balance of iron. The hardness of the slowly cooled metal alloy material is high, and is nearly twice as high as the hardness of 42CrMo steel or 35CrMnSi steel or other ordinary medium-carbon alloy structural steel, moreover, the wear-resistant property of the metal alloy material is high, a slowly cooled part made of the metal alloy material has higher hardness, better wear-resistant property and higher strength, the service life of the part is increased by three to five times in comparison with the service life of a part made of 42CrMo steel or 35CrMnSi steel or other ordinary medium-carbon alloy structural steel, consequently, the part replacement frequency is greatly decreased, the production efficiency is increased, and the production cost is reduced.
Description
Technical field
the present invention relates to a kind of metal alloy compositions.
Background technology
The hardness of common medium carbon structural alloy steel after slow cooling such as
42CrMo steel or 35CrMnSi steel are lower; Its HRC value can only reach 20～30 usually; And wear resisting property is low, when being used to make a few thing inclement condition, requires that higher hardness is arranged, preferably during the component of wear resistance and higher-strength; Work-ing life is short partially, influences production efficiency and production cost.
Summary of the invention
technical problem to be solved by this invention is to provide that a kind of hardness is higher, wear resisting property good, the metal alloy compositions of long service life, thereby overcomes the problem that prior art exists.
are for solving the problems of the technologies described above technical scheme of the present invention: a kind of metal alloy compositions.This material calculates according to weight percent, is composed of the following components: carbon 0.40～1.00%, and silicon 0.60～2.00%, manganese 2.00～4.00%, chromium 0.10～0.50%, titanium 0.08～0.60%, rare earth 0.01～0.20%, all the other are iron.
above-mentioned metal alloy compositions, the weight percent of each component is reasonable to be: carbon 0.60～0.85%, silicon 0.90～1.80%; Manganese 2.20～3.20%, chromium 0.15～0.30%, titanium 0.10～0.40%; Rare earth 0.05～0.15%, all the other are iron.
aforesaid metal alloy compositions, the weight percent of each component better is: carbon 0.70～0.80%, silicon 1.20～1.60%, manganese 2.40～3.00%, chromium 0.20～0.30%, titanium 0.20～0.30%, rare earth 0.05～0.09%, all the other are iron.
beneficial effect of the present invention: compared with prior art; The hardness of the present invention after slow cooling is higher; Its HRC value can reach 50～60, improve nearly one times than the hardness (the HRC value is 20～30) after the common medium carbon structural alloy steel slow cooling such as 42CrMo steel or 35CrMnSi steel, and its wear resisting property is good; Cost is low, can be used for making the component that require to have higher hardness and wear resistance after cutting pick body and other slow cooling of coalcutter.The component that use the present invention to make have higher hardness and wear resisting property, higher intensity preferably after slow cooling; The component of common medium carbon structural alloy steel such as work-ing life comparable employing 42CrMo steel or 35CrMnSi steel etc. improve 3～5 times; Significantly reduced the replacing frequency of component; Improve production efficiency, reduced production cost.
are further described the present invention below in conjunction with embodiment.
