Material 16Mo3 is the commonly used alloy grade specified in EN 10028 and EN17175 standard. WLD steel supply and stock the 16Mo3 seamless steel pipe in various sizes and specifications, delivered by heat treatment normalized or normalizing + tempering, which is a common material in the boiler system. WLD steel not only do we have all kinds of sizes and other material, but we also have all kinds of sizes that are hard to find.
