304不锈钢管件执行标准
随着经济的发展，技术的革新，时代的进步，物质生活水平的提高，不锈钢被越来越多的应用到人们的日常生活中来。现在就我国目前市面上应用比较多的不锈钢钢管执行标准做一下介绍： BS 4677-1984 Specification for arc welding of austenitic stainless steel pipework for carrying fluids 输送液体用奥氏体不锈钢管件
304不锈钢管件表面处理常见问题
304不锈钢管件表面着色处理：一、表面本色白化处理：不锈钢在加工过程中，经过卷板、扎边、焊接或者经过人工表面火烤加温处理，产生黑色氧化皮。这种坚硬的灰黑色氧化皮主要是NiCr2O4和NiF二种EO4成分，以**般采用氢氟酸和硝酸进行强腐蚀方法去除。但这种方法成本大，污染环境，对人体有害，腐蚀性较大，逐渐被淘汰。目前对氧化皮处理方法主要有二种： ⑴喷砂（丸）法：主要是采用喷微玻璃珠的方法，除去表面
