Low-alloy steel pipe model summary

Low alloy steel pipe, mostly used to transport a variety of higher temperature oil, oil and gas and corrosive salt water, low concentration of organic acids. Today we introduce you what models of low

Low-alloy heat-resistant steel welding process points

Alloy heat-resistant steels with a total alloy element mass fraction of 5% or less are collectively known as low-alloy heat-resistant steels, and their alloy series include Mo, Cr-Mo, Mo-V, Cr-Mo-V, M

Welding of low alloy heat resistant steel

The strength properties of carbon steels decline sharply with the increase in working temperature, and their ultimate working temperature is about 350°C. If they are used at higher temperatures, certa

How straight seam steel pipe is measured in length

According to the production process of LSAW steel pipe, we can be divided into two kinds of high-frequency LSAW steel pipe and submerged arc welding LSAW steel pipe, and we would like to know the form
