ASME SA871 Type III Grade 65 Introduction
ASME SA871 Type III Grade 65 is a weather resistant steel produced by alloying copper, chromium and nickel. In addition, ASME SA871 Type III Grade 65 has added phosphorous, which makes the material best suited for gas flue applications and for aesthetic facias. The material is not recommended in heavy load bearing applications – in this case Corten B or S355J2W should be considered.
The top layer of the material reacts with atmospheric elements to form a rust coloured protective layer, which not only makes the steel virtually maintenance free but also provides a pleasing and consistent finish.
According to A6/A6M Standard requirement, Structural steel impacts test sampling method according to A673/673M. Steel should be used in fine grain production process.
