Abstract
The invention relates to the technical field of special-shaped steel tubes, and in particular relates to a special-shaped steel tube with corrosion resistance and a preparation method thereof. The special-shaped steel tube comprises the following chemical compositions in percentage by weight: 0.5-1% of carbon, 0.5-1% of nitrogen, 10-15% of chromium, 0.15-2% of silicon, 20-32% of manganese, 0.5-1.6% of phosphorus and the balance of iron and impurities. The special-shaped steel tube with corrosion resistance provided by the invention not only has excellent corrosion resistance, but also has very high yielding limit and tensile strength and an elongation at break of more than 90%.
Description
Technical field
The present invention relates to chapped pipe technical field, especially relate to a kind of erosion resistance chapped pipe and preparation method thereof.
Background technology
Shaped steel is one of large kinds of steel four (type, line, plate, pipe), is a kind of widely used steel.Along with improving constantly of China's industrialized level in recent years, China produces the level of rolled section steel than significantly being promoted last century.More and more concern the shaped steel of national economy and progressively realize production domesticization as large H-shaped steel, high ferro heavy rail etc., even some has also reached international most advanced level.But we also find simultaneously, in the production and research and development of a lot of middle-size and small-size deformed steels, the level of the deformed steel manufacturer of China is compared or has very large poor certificate with the producer of a lot of countries in Europe.Particularly, in the control of dimensional precision, the treatment of details of section form, good multi-product does not also reach their level far away.In recent years, a lot of private producers, after recognizing this gap, study hard, study external advanced technologies and knowhow, actual in conjunction with the production of oneself, through constantly groping, well multi-field, have made gratifying achievement.But the problem of its corrosion-resistant remains present stage need to face a major issue.
Summary of the invention
