Stainless Steel Pipe-Encyclopedia

304 and 316L stainless steel materials are the only health materials that can be implanted into human body, so for water supply pipes, stainless steel pipes are the most beneficial to health. In the immersion water test, all the indicators meet the requirements of the relevant national drinking water standards. Stainless steel pipeline has smooth inner wall, no fouling, no bacterial contamination, anti-bacterial, anti-seismic, anti-tension, high pressure and high temperature resistance, no need to worry about water quality, and can prevent secondary pollution of water.Thin wall stainless steel water supply pipe is recognized as one of the best pipes with comprehensive properties

304不銹鋼水管的加工工藝

2019/8/20 13:12:45

現(xiàn)如今,社會(huì)經(jīng)濟(jì)發(fā)展迅速,說(shuō)起304不銹鋼水管,我們大家應(yīng)該都不會(huì)覺(jué)得陌生,因?yàn)?04不銹鋼水管在我們的日常生活中應(yīng)用非常廣泛。我們都知道,304不銹鋼水管常常用于制作要求良好綜合性能(耐腐蝕和成型性)的設(shè)備和機(jī)件。下面就一起來(lái)看看304不銹鋼水管有哪些加工工藝吧。

1.熱處理工藝

304不銹鋼管的固溶處理溫度為1080-1100℃,冷卻方式為水冷或空冷。冷加工中間退火溫度多在850-970℃,保溫一定時(shí)間后水冷。經(jīng)固溶處理后鋼的組織為奧氏體組織,有時(shí)也存在少量鐵素體。

2 焊接

304不銹鋼管抑制焊接時(shí)的碳化物析出,可采用通用的方法進(jìn)行焊接。手工電弧焊,含碳0.04%-0.06%的薄截面尺寸的304不銹鋼可采用奧002焊條,焊后可不產(chǎn)生晶間腐蝕傾向,對(duì)于厚截面尺,要保持焊后的耐晶間腐蝕性能,需進(jìn)行焊后熱處理,若不熱處理,應(yīng)改為304L不銹鋼或穩(wěn)定型奧氏體不銹鋼。

3.冷成型性能

304不銹鋼薄板在應(yīng)用過(guò)程中,常常用于冷成型操作。其冷成型性能是衡量能否順利成型和成品率高低的重要技術(shù)指標(biāo)。影響304不銹鋼的冷成型因素較多,也很復(fù)雜。就其金屬學(xué)因素來(lái)講主要是鋼的成分,即鉻當(dāng)量和鎳當(dāng)量之比,其常規(guī)拉伸性能中的延伸率是一個(gè)重要的表征指標(biāo)。為了獲得良好的冷成型性能,應(yīng)控制鋼中的鉻當(dāng)量和鎳當(dāng)量的比值處于一個(gè)適當(dāng)?shù)姆秶?

4.應(yīng)用

食品用設(shè)備,一般化工設(shè)備,原子能工業(yè)用裝置部件等,均被廣泛應(yīng)用。適于深沖件和輸酸管道、容器等。車輛、汽車零件盒家用器具也都采用該鋼種。它是奧氏體不銹鋼中生產(chǎn)和用量最多的鋼,用于生產(chǎn)薄壁件、輸酸管道及結(jié)構(gòu)件等。也經(jīng)常作焊接鉻鎳不銹鋼和不銹鋼的芯材,非磁性部件以及低溫環(huán)境下使用的部件等。

以上就是304不銹鋼水管的主要加工工藝,不知道大家清楚了嗎?
