Our company is a valve manufacturer, and now our client is asking us to conduct microstructural tests and corrosion resistance tests on our test bars (made of duplex steel ASTM A995 4A), and to provide test reports. Laboratories requiring an ISO 17025 certificate: 1. Conduct microstructural tests on harmful phases and ferrite structures in accordance with ASTM E562, ASTM A923 Cl.2.5.1 & 2.5.2, and SPE 77/302 2014 standards, and issue reports thereon. 2. Conduct corrosion resistance tests on duplex steel in accordance with ASTM G48 Method A, SPE 77/302-2014, Cl2.4.3, and prepare a report thereon. Is it better to be in Shanghai or nearby cities? I hope everyone here can help provide relevant information. Thank you! My QQ number is 278163526, and my email address is 278163526@qq.com
