Abstract
The invention discloses a large-caliber bushing ring flange. The large-caliber bushing ring flange is formed by compositing chromium, manganese and zinc, wherein the chromium takes up 30%-40% of the mass percentage of the large-caliber bushing ring flange, the manganese takes up 18%-22% of the mass percentage of the large-caliber bushing ring flange, and the zinc takes up 43%-48% of the mass percentage of the large-caliber bushing ring flange; the large-caliber bushing ring flange is 2.5 cm thick with the diameter of 10 cm. In this way, the large-caliber bushing ring flange can bear different degrees of pressure, so that the quality of the product is improved, and the use rate of the product is increased.
Description
Technical field
The present invention relates to flange field, particularly relate to flange with heavy caliber bushing ring.
Background technique
In 304 stainless steels, of paramount importance element is Ni, Cr, but is not limited only to again this two elements.Concrete requirement is specified by product standard.As long as the common judgement situation of industry thinks that Ni content is greater than 8%, Cr content and is greater than 18%, just 304 stainless steels can be thought.This is also why this kind of stainless steel can be called 18/8 stainless reason in the industry.In fact, relevant product standard has the regulation be perfectly clear to 304 stainless steels, and these product standards have some differences for difform stainless steel.。
Summary of the invention
The technical problem that the present invention mainly solves is to provide one, can improve processibility and the toughness of flange, has good good combination property.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide flange with heavy caliber bushing ring, comprise: chromium, manganese, zinc combines, and wherein, the mass percent that described chromium accounts for described flange with heavy caliber bushing ring is 30%-40%, the mass percent that described manganese accounts for described flange with heavy caliber bushing ring is 18%-22%, and the mass percent that described zinc accounts for described flange with heavy caliber bushing ring is 43%-48%; The thick 2.5cm of described flange with heavy caliber bushing ring, diameter is 10cm.
In a preferred embodiment of the present invention, the mass percent that described chromium accounts for described flange with heavy caliber bushing ring is 35%.
In a preferred embodiment of the present invention, the mass percent that described manganese accounts for described flange with heavy caliber bushing ring is 20%.
In a preferred embodiment of the present invention, the mass percent that described zinc accounts for described flange with heavy caliber bushing ring is 45%.
The invention has the beneficial effects as follows: the present invention can bear pressure in various degree, improve quality and the utilization rate of product.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Flange with heavy caliber bushing ring, comprise: chromium, manganese, zinc combines, wherein, the mass percent that described chromium accounts for described flange with heavy caliber bushing ring is 30%-40%, and the mass percent that described manganese accounts for described flange with heavy caliber bushing ring is 18%-22%, and the mass percent that described zinc accounts for described flange with heavy caliber bushing ring is 43%-48%; The thick 2.5cm of described flange with heavy caliber bushing ring, diameter is 10cm;
In another embodiment, the mass percent that described chromium accounts for described flange with heavy caliber bushing ring is 35%.
In another embodiment, the mass percent that described manganese accounts for described flange with heavy caliber bushing ring is 20%.
In another embodiment, the mass percent that described zinc accounts for described flange with heavy caliber bushing ring is 45%.
Be different from prior art.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
