Three Questions About Steel Pipe Surface Conditions
1. How is Decarburization Caused in Steel Pipes? Decarburization occurs when the oxidation rate on the steel pipe surface is slower than the carbon diffusion rate. Both oxidation and carbon diffusion occur intensely at temperatures above the A1 transformation point. Decarburization can be control...Read more -
Comprehensive Performance and Precautions of IPN8710 Corrosion-Resistant Steel Pipe
IPN8710 corrosion-resistant steel pipe is essential for extremely dark, humid, and corrosive environments.
