Abstract
The invention discloses a special wear-resistant steel tube for a baby stroller. The special wear-resistant steel tube is prepared from the following components in percentage by mass: 0.8-1.0% of C, 4-4.5% of Cr, 1.4-1.6% of Mn, 3.5-3.8% of Si, 0.4-0.5% of Cu, 0.4-0.6% of Ni, 0.02-0.03% of Re, less than or equal to 0.04% of S, less than or equal to 0.04% of P and the balance of Fe. The wear-resistant stele tube disclosed by the invention is reasonable in formula, the shrinkage porosity and shrinkage cavities of the produced steel tube are reduced, the steel tube is good in mechanical property, good in wear resistance and toughness, the hardness is 44-48HRC, the impact value is greater than or equal to 18J/cm<2>, and the service life is prolonged by 1.5-2 times; and the integral safety performance of the baby stroller is improved.
Description
Technical field
The present invention relates to doll carriage technical field, be specifically related to a kind of wear-resistant steel pipe being exclusively used in doll carriage.
Background technology
Doll carriage is baby's " vehicles ", and needing people and assist to push or haul the car just can walked, doll carriage, is baby's favorite doll carriage stroll vehicles, requisite when mother goes shopping with baby especially.But according to the growth of baby, use, doll carriage can be divided into many types again, as: twin babies go-cart, high view doll carriage, sunshade doll carriage etc.Be mainly standard according to weight-carrying capacity, general test standard is nine to ten five kilograms, and general perambulator approximately can use 3 to five years.
High-abrasive material is the core of field of new, plays important promotion and supporting role to the development of new and high technology, and in global new material research field, high-abrasive material accounts for 85%.Along with the arrival of information society, the development of special, wear-resistant material to new and high technology plays important promotion and supporting role, be 21st century information, biology, the energy, environmental protection, the high-tech sector such as space critical material, becoming the emphasis of countries in the world field of new researchdevelopment, is also the focus of Strategic Competition in the high technology development of countries in the world.
In prior art, doll carriage is not enough by steel pipe mechanical performance, haves much room for improvement.
Summary of the invention
For the problems referred to above, the invention provides a kind of wear-resistant steel pipe being exclusively used in doll carriage, good mechanical property, improve the safety performance of go-cart.
In order to solve the problem, technical scheme provided by the invention is:
Be exclusively used in a wear-resistant steel pipe for doll carriage, each composition and mass percent thereof are: C:0.8-1.0%, Cr:4-4.5%, Mn:1.4-1.6%, Si:3.5-3.8%, Cu:0.4-0.5%, Ni:0.4-0.6%, Re:0.02-0.03%, S :≤0.04%, P :≤0.04%; Surplus is Fe.
Preferably, each composition and mass percent thereof are: C:0.85-1.0%, Cr:4.2-4.5%, Mn:1.45-1.6%, Si:3.6-3.8%, Cu:0.42-0.5%, Ni:0.45-0.6%, Re:0.02-0.03%, S :≤0.04%, P :≤0.04%; Surplus is Fe.
Preferably, each composition and mass percent thereof are: C:0.85%, Cr:4.4%, Mn:1.45%, Si:3.6%, Cu:0.48%, Ni:0.45%, Re:0.028%, S:0.04%, P:0.02%; Surplus is Fe.
Preferably, each composition and mass percent thereof are: C:0.95%, Cr:4.2%, Mn:1.55%, Si:3.7%, Cu:0.42%, Ni:0.55%, Re:0.025%, S:0.02%, P:0.04%; Surplus is Fe.
Compared with prior art, beneficial effect of the present invention is:
Wear-resistant steel pipe of the present invention, formulation selection is reasonable, and the shrinkage porosite of the steel pipe produced, shrinkage cavity produce and reduce, and good mechanical property, hardness: 44-48HRC, wear resistance is good, good toughness, impact value>=18J/cm
2, work-ing life improves 1.5-2 times, improves the general safety performance of doll carriage.
