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304和316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1、2年就重新安装的窘境。
不锈钢材料的鉴别
不锈钢材料有201,201,301,302，304,316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(见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DM、DH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。
