Abstract
The invention relates to heat-resistant steel for an automobile exhaust pipe. The heat-resistant steel is characterized by comprising the following components by weight percent: 0.05% to 0.25% of C, less than 1.0% of Si, 1.6% to 2.0% of Mn, less than or equal to 0.06% of P, less than or equal to 0.05% of S, less than or equal to 0.2% of Cu, less than or equal to 0.10% of As, 1.2% to 2.0% of Cr, 10.0% to 20.0% of Ni, 10.5% to 15.0% of Mo and the balance of Fe and impurities. The heat-resistant steel is capable of resisting a high temperature reaching 1000 DEG C, thereby being better in high-temperature performance. The alloy metallographic structure of the heat-resistant steel is stabilized even under the condition that the temperature is changed sharply. Thus, the applicable life of the exhaust pipe is ensured.
Description
Technical field
The present invention relates to the effective high temperature steel of a kind of auto exhaust.
Background technology
At present, material one stainless steel of automobile exhaust pipe is main, in winter, and the large automobile of more corresponding quantity dischargeds, in long-distance running, the temperature of vapor pipe is high especially, is easy to cause flame-out of engine, and in winter, because the vapor pipe of excessive temperature is again in the environment as for very low temperature, temperature moment decline, is easy to make vapor pipe to receive damage, and the life-span impact of corresponding vapor pipe is very large.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide the technical scheme of the effective high temperature steel of a kind of auto exhaust.
The described effective high temperature steel of a kind of auto exhaust, is characterized in that each components based on weight percentage of this high temperature steel is: C:0.05%-0.25%; Si:< 1.0%; Mn:1.6%-2.0%; P :≤0.06%; S :≤0.05%; Cu :≤0.2%; As :≤0.10%; Cr:1.2%-2.0%; Ni:10.0%-20.0%; Mo:10.5%-15.0%; All the other are Fe and impurity.
The described effective high temperature steel of a kind of auto exhaust, is characterized in that the described various components based on weight percentage of high temperature steel are: C:0.08%-0.22%; Si:< 0.8%; Mn:1.7%-1.9%; P :≤0.05%; S :≤0.04%; Cu :≤0.15%; As :≤0.09%; Cr:1.4%-1.9%; Ni:13.0%-27.0%; Mo:11.5%-14.0%; All the other are Fe and impurity.
The described effective high temperature steel of a kind of auto exhaust, is characterized in that described each components based on weight percentage of high temperature steel is: C:0.10%-0.20%; Si:< 0.7%; Mn:1.75%-1.85%; P :≤0.045%; S :≤0.035%; Cu :≤0.10%; As :≤0.08%; Cr:1.6%-1.8%; Ni:15.0%-25.0%; Mo:12%-13.0%; All the other are Fe and impurity.
