如何挑选上等的不锈钢材料

不锈钢材料性价比高,耐高温、耐酸、耐碱、耐腐蚀、抗静电的特点使不锈钢材料在工业生产各方面的到较高评价,被美誉为:世界上*佳的建筑材料之一。

不锈钢材料的选择主要从材质和粗细两方面着手。先说材质,目前市场上*好的不锈钢材料是316不锈钢材料、其次是304不锈钢材料。这两种材质的不锈钢材料具有优良的防腐性能。使用寿命可达20年。但在抗腐蚀性能上316钢丝要比304强得多,购买不锈钢材料的时候谨慎对待低价不锈钢材料。市面上低价不锈钢材料多的是。钢材型号大都不是304316的。

202不锈钢材料、302不锈钢材料或者高精不锈钢材料等,这类材质的不锈钢材料使用寿命不超过5年,一般3年不到就会出现生锈腐蚀,快的1年就生锈了,但这种不锈钢材料价格低廉。一些无良商家利用低价为诱饵,用其他牌号的劣质不锈钢材料以次充好,误导消费者。好多消费者经不住价格诱惑,或销售人员忽悠,结果面临刚装上12年就重新安装的窘境。

不锈钢材料的鉴别

不锈钢材料有201,201,301,302304,316等,*好在安装施工时,用不锈钢测试液测试一下,几分钟即可得到结果,根据测试液显示颜色可判定钢丝型号。316例外,这种型号可用M2钼测试液检测

1)明确是采用生拉不锈钢材料还是铅淬火钢丝;

2)提出不锈钢材料直径、强度级别(组别)及标准号(按表1.1选择)要求;

3)如有特殊的强度、直径允许误差等要求应提出(标准参数在第2及第3部分);

4)特殊包装及标志要求(1.4);

5)碳钢弹簧适合在*高长期温度121℃条件下工作,更工作温度应选用合金弹簧钢。

3特殊需求

不锈钢材料异形截面:方形、矩形、六角形等。

不锈钢材料退火处理:适合再进行大变形塑性加工,如压扁、轧成三角形等。

不锈钢材料稳定化处理:钢丝放出后会弹直,残余应力消除较好。

表面状态:标准状态为磷化后冷拉状态,其它特殊状态有镀锌、镀镍及无磷化等。

琴钢线:按ISO标准的DMDH级别,或按JISG3522标准交付。

合金弹簧钢丝:本资料仅包括碳钢,合金钢丝可按退火及冷拉状态供应。

特殊需**否能满足要在订购时确认。

不锈钢材料交付时采用盘卷包装,特殊包装(木箱、铁桶、托盘、线架)可协商。

所有弹簧钢丝涂以防锈油,不需要涂油时应在订购时申明。盘卷装钢丝绑扎后用塑料编织布或其它材料包装。
