Abstract
The invention discloses a highly corrosion-resistant and abrasion-resistant alloy steel in a thiamine mother liquor. The alloy steel comprises the following chemical compositions in percentage by weight: 0.03% of carbon (C), 20% of chromium (Cr), 20% of nickel (Ni), 5% of molybdenum (Mo), 2% of copper (Cu), less than or equal to 2% of silicon (Si), less than or equal to 2% of manganese (Mn), less than or equal to 0.2% of nitrogen (N), less than or equal to 0.3% of rare earth (Ti and Re), and the balance of ferrum (Fe). The highly corrosion-resistant and abrasion-resistant alloy steel in the thiamine mother liquor, provided by the invention, has very high corrosion resistance and abrasion resistance to liquid or granules of dilute sulfuric acid and the thiamine mother liquor, and is suitable for being used as a pump body material and an overflow material of a pump. Compared with the prior art, the cost of the highly corrosion-resistant and abrasion-resistant alloy steel can be reduced about 20%, and the service life of the alloy steel is longer than 4 years.
Description
Technical field
The present invention relates to a kind of steel alloy, relate in particular to the steel alloy of highly corrosion resistant and abrasion in a kind of thiamines mother liquor.
Background technology
In coal chemical enterprise, the liquid or the granule that contain thiamines mother liquor need to transmit in pipeline, and are transported to appointed place through devices such as pump valves.Because this material has extremely strong corrodibility, the devices such as pump valve used generally just need to change using about six months.
Summary of the invention
The present invention has overcome shortcoming of the prior art, and the steel alloy of highly corrosion resistant and abrasion in a kind of thiamines mother liquor is provided.
In order to solve the technical problem of above-mentioned existence, the present invention is achieved by the following technical solutions: the steel alloy of highly corrosion resistant and abrasion in a kind of thiamines mother liquor, and the chemical composition of described steel alloy and mass percent thereof are: carbon (C): 0.03%, chromium (Cr): 20%, nickel (Ni): 20%, molybdenum (Mo): 5%, copper (Cu): 2%, silicon (Si) :≤2, manganese (Mn) :≤2, nitrogen (N) :≤0.2, rare earth (Ti, Re) :≤0.3, surplus is iron (Fe).The beneficial effect that in a kind of thiamines mother liquor provided by the invention, the steel alloy of highly corrosion resistant and abrasion has is:
The steel alloy of highly corrosion resistant and abrasion in a kind of thiamines mother liquor provided by the invention, has extremely strong erosion resistance and resistance to abrasion for dilute sulphuric acid with containing liquid or the granule of thiamines mother liquor, is applicable to the material for flow as pump housing material and pump.The present invention can reduce costs 20% left and right with respect to prior art, and be more than 4 years its work-ing life.
