JIS G3454 STPG 370 Carbon Steel Pipes

STPG370 is a low-carbon steel pipe material commonly used in some low-pressure pipeline systems.

standard:JIS

Surface :1. Galvanized 2. Black and Color Painting

introduction

JIS G3454 Grade STPG 370 Tubes are low-cost Low Carbon Steel Tubes with max 025 % carbon content with combination of 030-090 % manganese easy to form and shape .
The minimum yield strength of the pipes is 216MPa and the minimum tensile strength is 373MPa. There are different schedules to the pipes such as the JIS G3454 Stpg370 Sch40 Pipe depending on the wall thickness and outer diameter. The material has carbon, silicon, manganese, phosphorus and sulfur.
STPG370 Carbon Steel Seamless Pipe has a wide range of applications. First, it is often used in water piping systems. Because STPG370 low-carbon round pipe has good processability and corrosion resistance, it is suitable for urban water supply, farmland irrigation and other fields.
