04不锈钢管是根据美国ASTM尺度消费出来的不锈钢的一个商标。304不锈钢管相当于我国的0Cr19Ni9 (0Cr18Ni9)不锈钢管。304露铬19%,露镍9%。

04 stainless steel pipe is a grade of stainless steel produced in accordance with American ASTM standard. The 304 stainless steel pipe is equivalent to the 0Cr19Ni9 (0Cr18Ni9) stainless steel pipe in our country. 304 chromium containing 19%, containing nickel 9%.

304不锈钢管作为不锈耐热钢运用最普遍,食物用装备,一样平常化工设备,原子能产业用装备。

304 stainless steel tube is the most widely used stainless steel, food equipment, general chemical equipment, atomic energy industrial equipment.

304 不锈钢管是一种通用性的不锈钢管,它普遍天用于建造要求优越综合机能(耐侵蚀和成型性)的装备和机件。

304 stainless steel pipe is a kind of universal stainless steel pipe, it is widely used in the manufacture of equipment and machinery requiring good comprehensive performance (corrosion resistance and formability).

304不锈钢管是获得最普遍运用的不锈钢、耐热钢。用于食物消费装备、昔通化工装备、核能等.

304 stainless steel pipe is the most widely used stainless steel and heat resistant steel. It is used for food production equipment, chemical equipment, nuclear energy and so on.

正在氛围中或化学侵蚀介质中可以或许反抗侵蚀的一种下合金钢,不锈钢是具有雅观的外面和耐侵蚀机能好,没必要经由镀色等外面处置惩罚,而施展不锈钢所固有的外面机能,运用于多方面的钢铁的一种,一般称为不锈钢。代表性能的有13铬钢,18-8铬镍钢等下合金钢。

A kind of high alloy steel which can resist corrosion in air or chemical corrosion medium. Stainless steel is a kind of stainless steel, which has beautiful surface and corrosion resistance and does not have to be treated by plating color. The representative properties include 13 chromium steel, 18-8 chromium nickel steel and other high alloy steels.

从金相学角度剖析,由于不锈钢含有铬而使外面构成很薄的铬膜,这个膜断绝开取钢内侵入的氧气起耐侵蚀的感化。为了连结不锈钢所固有的耐腐蚀性,钢必需含有12%以上的铬。

From the metallographic point of view, because the stainless steel contains chromium, it causes the surface to form a thin chromium film. The membrane separates from the oxygen intruded in the steel and is resistant to corrosion. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium.

321不锈钢管用无缝钢管(GB3087-1999)是用于制造种种构造低中压汽锅过热蒸汽管、滚水管及机车汽锅用过热蒸汽管、大烟管、 小烟管和拱砖管用的优良碳素结构钢热轧和热拔(轧)无缝钢管。

321 seamless steel pipe (GB3087-1999) for stainless steel pipe is used to make hot and cold (rolled) seamless steel tubes of superheated steam pipes, boiling water pipes and locomotive boilers for all kinds of low medium pressure boiler, superheated steam pipes, large smoke pipes, small smoke pipes and arch brick pipes.

321不锈钢管:重要用来制造高压及其以上压力的蒸汽锅炉管道等用的优良碳素结构钢、合金结构钢和不锈耐热钢无缝钢管、这些锅炉管经党处于下温文高压下工做、管子正在高温烟气和水蒸汽的感化下还会发作氧化和侵蚀,因而要求钢管有下的耐久强度、下的抗氧化机能,并具有优越的构造稳定性,液压支柱管。

321 stainless steel pipe: high quality carbon structural steel, alloy structural steel and stainless steel seamless steel pipe used for the production of high pressure and above pressure steam boiler pipes. These boiler tubes work under high temperature and high pressure, and the pipes will also be oxidized and corroded under the high temperature smoke and steam. It is required that the steel pipe has high endurance strength, high oxidation resistance and good structural stability.

321不锈钢管接纳钢号有:

321 stainless steel tube is made of steel number:

优良碳素结构钢钢号有20G、20MnG、25MnG;304不锈钢管。

The quality carbon structural steel No. 20G, 20MnG, 25MnG; 304 stainless steel pipe.

合金结构钢钢号15MoG、20MoG、12CrMoG、15CrMoG、12Cr2MoG、 12CrMoVG、12Cr3MoVSiTiB等;有锈耐热钢常用1Cr18Ni9、1Cr18Ni11Nb高压锅炉管除包管化学成分和机械性能中,要逐根做水

Alloy structure steel steel number 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.; rust resistant steel is commonly used in 1Cr18Ni9 and 1Cr18Ni11Nb high pressure boiler tubes to ensure chemical composition and mechanical properties, to make water by root.

压实验,要作扩口、压扁实验。

Pressure test, to make expansion, flatting test.

321不锈钢管以热处理状况交货。另外,对制品钢管显微构造、晶粒度、脱碳层也有一定要供。地质钻探及石油钻控用无缝钢管;为探明地下岩层构造、地下水、石油、天然气及矿产资源状况,应用钻机打井。

321 stainless steel pipe is delivered in heat treatment. In addition, the microstructure, grain size and decarburization layer of finished steel pipe also have certain requirements. Seamless steel pipes for geological drilling and oil drilling control; drilling rigs are used to drill wells in order to explore underground rock structure, groundwater, petroleum, natural gas and mineral resources.
