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

不銹鋼中主要元素的作用

2019/7/5 16:53:15

不銹鋼作為較具附加值的特殊鋼產(chǎn)品,其應(yīng)用領(lǐng)域越來越廣泛,無論是在民用領(lǐng)域如裝飾、餐廚具、家電等;還是工業(yè)領(lǐng)域如石油化工、機械設(shè)備等均得到了廣泛的應(yīng)用,目前高質(zhì)量的不銹鋼產(chǎn)品市場前景依然看好。下面,就讓我們一起來了解認識一下生產(chǎn)不銹鋼所需的主要相關(guān)元素的功能:

鎳:鎳系不銹鋼最重要的核心元素,其能提高鋼的強度和韌性,提高淬透性.含量高時,可顯著改變鋼和合金的一些物理性能,提高鋼的抗腐蝕能力。

錳:能提高鋼的強度,能消弱和消除硫的不良影響,并能提高鋼的淬透性,含錳量很高的高合金鋼(高錳鋼)具有良好的耐磨性和其它的物理性能。

鉻:能提高鋼的淬透性和耐磨性,能改善鋼的抗腐蝕能力和抗氧化作用。

釩:能細化鋼的晶粒組織,提高鋼的強度,韌性和耐磨性。當它在高溫熔入奧氏體時,可增加鋼的淬透性;反之,當它在碳化物形態(tài)存在時,就會降低它的淬透性。

鉬:可明顯的提高鋼的淬透性和熱強性,防止回火脆性,提高剩磁和嬌頑力。

鈦:能細化鋼的晶粒組織,從而提高鋼的強度和韌性。在不銹鋼中,鈦能消除或減輕鋼的晶間腐蝕現(xiàn)象。

銅:它的突出作用是改善普通低合金鋼的抗大氣腐蝕性能,其在和磷配合使用時更為明顯。
