BAfinish 是指内BA面层的不锈钢容,面层有2B和BA的区别,冷扎--退火酸洗--平整 2B
冷扎--光亮退火--平整 BA
主要区别在于退火,2B是退火、酸洗,表面有一定程度氧化,较暗;BA光亮退火,表面不氧化,较亮。
B. 不锈钢BA处理是什么意思
不锈钢BA处理是来:BA(Bright Annealing), 光亮自退火处理,指不锈钢冷轧板经光亮退火处理,再经平整后的一种表面状态。
一、304不锈钢带钢BA处理后:

E. 不锈钢食品管BA表面是什么意思
不锈钢BA管――BrightAnnealedtube(真空光亮退火管),它是气氛保护热处理(BrightAnnealed)的简称,又叫:不锈钢BA管,洁净管,光亮退火管,无缝管. BA表面的定义来自于美国标准ASTM A480 和欧盟标准EN10088。见下列英文解释。
The most common definitions of these surface finishes are provided by ASTM A480 and EN 10088. In both cases it is the cold rolled manufacturing method that is specified rather than specific, measurable characteristics about the surface. We have used ASTM A480 as an example:
ASTM A480:
No. 2D - A smooth, non-reflective cold-rolled annealed and pickled or descaled finish. This non-directional finish is favourable for the retention of lubricants in deep drawing applications.
No. 2B - A smooth, moderately reflective cold-rolled annealed and pickled or descaled finish typically proced by imparting a final light cold-rolled pass using [large diameter] polished rolls. This general-purpose finish is more readily polished than No 1 or 2D finishes. Proct with 2B finish is normally supplied in the annealed plus lightly cold-rolled condition unless a tensile-rolled [harder and stronger] proct is specified.
Bright Annealed [BA] Finish- A smooth, bright, reflective finish typically proced by cold rolling followed by annealing in a protective atmosphere so as to prevent oxidation and scaling ring annealing.
2B
2B is the most widely used stainless steel surface finish. It is especially common in instrial, chemical and food processing applications such as process vessels and tanks. It is also used in some architectural applications that will not be closely examined for uniformity of finish such as downpipes and gutters.
When specifying this finish think about these attributes:
2B is the most economical finish
It is highly corrosion resistant because it has been chemically pickled and is smooth
Over broad areas and between batches etc., it is not uniform and may not match in appearance
It has been proced in the mill and can't be matched after fabrication
It if often protected by plastic films until final cleanup and commissioning
2D
2D is used around the world in applications where its low reflectivity is important. The largest application is in roofing materials. The surface is rougher than 2B and retains lubricants better making it appealing for deep drawring. 2D surfaces are not designed for appearance so the limitations on matching of weld and other surface damage is not as critical. Railcars are a typical example where thicker sheet and ongoing abrasive damage make the rougher 2D a suitable finish.
When specifying this finish think about these attributes:
2D is not commonly available in Australia
It is highly corrosion resistant because it has been chemically pickled and is relatively smooth
Over broad areas and between batches etc., it is not uniform and may not match
It has been proced in the mill and can't be matched after fabrication。
Bright Annealed (BA)
The classic use of a BA finish is domestic: the interior of a dishwasher or clothes washing machine. In the clothes washer, it also provides a smooth, non-abrasive surface for the clothes to slide around. The mirror like surface is also used in road mirrors where a precise image is not required.
When specifying this finish think about these attributes:
BA is common in some grades and thicknesses, but not all
It is highly corrosion resistant because it is very smooth
Different batches may not match
It is has been proced in the mill and can't be exactly matched after fabrication although a mechanical mirror polish can be close.
F. 不锈钢抛光管 EP BA AP 级代表什么程度
AP、BA光亮退火光洁来度<0.6um,源EP电解抛光光洁度<0.2um。
1、EP:电解研磨处理
通过电化学抛光,可以极大的提高表面形态及及结构,使表层面积得到极大的程度的减少。表面是一层封闭的、厚厚的氧化铬膜。能量接近合金的正常水平,同事介质数量也会降为最少。
微电子、光电子和生物制药等行业对传输敏感或腐蚀性介质的高纯、洁净管道系统一般都采用光亮烧钝(BA)、电解抛光(EP)产品。
2、BA:光亮固溶处理或称光亮退火;
在加氢或真空状态高温热处理,一方面消除内应力,另一方面在管道表面形成一层钝化膜,以改善形态结构,减少能量水平,但不会提高表面粗糙度。
3、AP:酸洗管
管道经过酸洗或钝化,不会提高表面粗糙度,单可以去除残存的颗粒,降低能量水平,但不会减少介层数量。
(6)不锈钢ba中的ba指什么扩展阅读:
不锈钢抛光亮度等级
目测法,将抛光后零件 表面的光亮度分为5级:
1级:表面有白色氧化膜,无光亮度;
2级:略有光亮,看不清轮廓;
3级:光亮度较好,能看出轮廓;
4级:表面光亮 ,较清晰地看出轮廓 (相当于电化学抛光的表面质量);
5级:镜面般光亮。
G. 不锈钢2B和BA面分别代表什么意思求解
不锈钢2B和BA面分别代表:
冷扎--退火酸洗--平整
2B
冷扎--光亮退火--平整
BA
主要区别在于退火,2B是退火、酸洗,表面有一定程度氧化,较暗;
BA光亮退火,表面不氧化,较亮
H. 什么是ba卫生级不锈钢管
ba卫生级不锈钢管是指那些工艺精度要求高、管壁光洁度高和需要进行脱脂去油处理。 这种管主要应用于生物制药、高纯气体、电子洁净车间和其它有超高纯要求的气体管道系统中。
I. 不锈钢级别中EP级、BA级、AP级、MP级都是什么意思,分别用在什么地方
AP:酸洗管(Anneal treatment & Passivation) /(Acid pickling)
MP: 机械研磨处理或称机械抛光 (Mechanical Polish)
BA:光辉烧钝处理或称光辉退火 (Bright Anneal treatment)/(Bright Annealing)
这里有回我知道的管道答材质处理流程,参考一下!
EP:光亮退火--->无损检测--->化学抛光---->电抛光;
BA:光亮退火--->无损检测--->一次清洗; l$ n" o# r$ U& a( ~
CP/AP:热处理--->无损检测--->化学抛光;
J. 不锈钢的2B 、BA是什么意思
L4不锈钢是广州联众的产品,相当于国标202不锈钢。
2B是指不锈钢的表面,版代表雾面,也叫2B雾面,照不出人影权的。2B面的不锈钢都是软态的,也就是硬度HV(维氏硬度)在150-200度。依次排序为2B面,哑光面,光亮面,BA面,6K,8K。BA以后就属于镜面了(包括BA)。
