不锈钢表面ba是什么意思

㈠ 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

㈡ 不锈钢8K和BA有什么区别。从材料表面怎么分辨

不锈钢表面等级分为2B，BA，4K，8K。。。BA可以照到比较模糊的人像，8K像镜子一样也是不锈钢表面最高等级，可以代替镜子。

㈢ 不锈钢板材的表面NO3/4、NO。1、BA、HL、MP 分别代表什么含义

NO3：中间研磨表面，单面或者双面处理
NO4：普通研磨表面，单面或者双面出来
NO1：热轧，退火，除氧化皮

BA：冷轧、光亮退火
HL：冷轧、酸洗、平整、研磨
MP：机械抛光

㈣ 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.

㈤ 不锈钢镜面板BA和8K的区别

朋友，不锈钢的面有分几种的，有2B，BA，普通面，8K面，8K面就是镜面的意思，BA面只有软料才有的面，我知道不多，只能告诉你这些，希望有人可以全部讲解出来，我也想知道下，谢谢大家！
我想交不锈钢行业的朋友，我是做不锈钢销售的，QQ：526399329

㈥ 我要买不锈钢带，材质表面是冷轧2B、BA、TR、HL是什么意思

2B（雾面）：抄
冷轧后经热处理、酸洗，再以精轧加工使表面为适度之光亮者。由于表面光滑，易于再研磨，使表面更加光亮，用途广泛，如餐具、建材等。采用改善机械性能的表面处理后，几乎满足所有用途。
BA （亮面）：
经冷轧后施以光亮退火，并经过平整得到的产品。表面光泽度极好，有很高的反射率。如同镜面的表面。用于家电产品、镜子、厨房设备、装饰材料等。
TR （各种规定要求表面）
对退火和除氧化皮或者光亮退火后的产品进行冷加工，得到的机械性能远高于退火状态材料性能，表面的不同取决于加工量大小和材料合金成分
HL（毛丝面）:
经适当粒度抛光砂带的连续研磨生成研磨花纹的产品（细分 150-320号）。主要用于建筑装饰，电梯，建筑物的门、面板等。
这样说希望对你有所帮助！！！

㈦ 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。

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。

㈧ 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）。

㈨ 不锈钢BA表面是什么样的，与2B比较，外观、工艺和用途上有什么不同

BA表面 外观上比较亮 类似镜面效果

304 的BA 2B表面区别很大 430的区别小一些
工艺的话 BA走的是光亮退火版线
用途上区别不大权 主要看产品要求美观就用BA
以前洗衣机都用BA 现在都改2B了
