Stainless steel is mainly used in elevator car decoration, ceiling, car door and hall door, door pocket, floor display, control panel and handrail, etc; It is applied to the skirt and inner and outer cover plates of the escalator, steps, access end cover plates and the outer decorative packages of the escalator.

其中，304不銹鋼的用量，316不銹鋼主要用在海邊、高腐蝕場合和重載扶梯，430不銹鋼一般用于梯級，443在某些特定情況下可部分替代304不銹鋼。電梯用不銹鋼板牌號有：

Among them, 304 stainless steel is the most widely used, 316 stainless steel is mainly used in seaside, high corrosion occasions and heavy-duty escalators, 430 stainless steel is generally used for stairs, and 443 can partially replace 304 stainless steel in some specific cases. The grades of stainless steel plates for elevators are:

1、常規(guī)300系奧氏體不銹鋼牌號：06Cr19Ni10（S30408，304）、022Cr19Ni10（S30403，304L）、022Cr17Ni12Mo2（S31603，316L）；

1. Conventional 300 series austenitic stainless steel grades: 06cr19ni10 (s30408304), 022cr19ni10 (s30403304l), 022cr17ni12mo2 (s31603316l);

2、400系鐵素體不銹鋼牌號：10Cr17（S11710，430）、022Cr17NbTi（S11763，439）、022Cr18Ti（S11863，439）、019Cr21CuTi（S12182，SUS443J1）；

2. 400 series ferritic stainless steel grades: 10cr17 (s11710430), 022cr17nbti (s11763439), 022cr18ti (s11863439), 019cr21cuti (s12182, sus443j1);

3、更多12Cr17Mn7Ni2Cu2N（QN1701）、08Cr19Mn6Ni3Cu2N（QN1803）、05Cr19Mn6Ni4Cu2N（QN1804）、05Cr19Ni6Mn4MoCu2N（QN1906）等四個高強度含氮奧氏體QN系不銹鋼牌號。

3. More 12cr17mn7ni2cu2n (qn1701), 08cr19mn6ni3cu2n (qn1803), 05cr19mn6ni4cu2n (qn1804), 05cr19ni6mn4mocu2n (qn1906) and other four high-strength nitrogen-containing austenitic QN stainless steel grades.

一般情況下電梯使用厚度為0.8毫米的不銹鋼，以10層樓為估計，我國三種尺寸的電梯對不銹鋼需求約249千克-345千克之間。

Generally, Elevators use stainless steel with a thickness of 0.8 mm. It is estimated that the demand for stainless steel for elevators of three sizes in China is about 249 kg -345 kg based on 10 floors.

另外，不銹鋼板材經(jīng)過處理后，表面光滑、光亮適度，呈現(xiàn)銀灰色，具有金屬色澤。為使不銹鋼起到豐富裝飾的作用，達到美觀的效果，就必須對不銹鋼進行表面加工，加工工藝可分為拉絲、鏡面拋光、鍍色等。

In addition, after treatment, the surface of stainless steel plate is smooth, moderately bright, silver gray and metallic. In order to make stainless steel play a role of rich decoration and achieve beautiful results, it is necessary to carry out surface processing on stainless steel. The processing technology can be divided into wire drawing, mirror polishing, color plating, etc.

目前，這些工藝應(yīng)用于電梯中廳門、吊頂、轎廂面板，起到豐富多樣的裝飾效果，給人們?nèi)A麗的感覺

At present, these processes are applied to the elevator hall door, ceiling and car panel, playing a variety of decorative effects and giving people a magnificent and noble feeling

電梯用不銹鋼對于質(zhì)量方面來說要求相對較高，其主要體現(xiàn)在以下三個方面：

Stainless steel for elevator has relatively high requirements for quality, which is mainly reflected in the following three aspects:

是板型平整，

The first is flatness,

一般要求無翹曲，無腹波浪，邊波浪也要控制在1mm以內(nèi);

Generally, there is no warpage, no belly wave, and the edge wave should also be controlled within 1mm;

第二是尺寸精度，

The second is dimensional accuracy,

一般要求控制在1mm以內(nèi)，超差則對鈑金或拼裝易造成影響;

Generally, it is required to be controlled within 1mm. If it exceeds the tolerance, it is easy to affect the sheet metal or assembly;

第三是表面要求，

The third is the surface requirements,

砂紋異常、色差、劃傷、壓點等表面缺陷都是不允許存在的。

Abnormal sanding, color difference, scratch, pressure point and other surface defects are not allowed.
