09CuPCrNi-A weather-resistant steel plate is one of weather-resistant steel (that is, atmospheric corrosion-resistant steel), used in sulfur-containing flue gas, air preheater, economizer, boiler air preheater, to prevent the vicinity of acid dew point, etc. Commonly used is low temperature weathering steel, which has a strong ability to resist low temperature corrosion. This type of steel 42crmo4+qt alloy steel plate equivalent has a protective effect against corrosion.

SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. 42crmo4+qt alloy steel plate equivalent, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
