JIS G4051 Seamless Steel Pipes For Machine Structure

Introduction

JIS G4051 seamless steel pipe is a type of carbon steel seamless pipes for machine structure. There are JIS G4051 Gr S20C, Gr S45C and Gr 50C seamless steel pipe can be supplied by us. Gr S20C and Gr S45C is equivalent to 20# and 45#, which is belong to high quality carbon structure steel and the carbon content is higher than common carbon steel. Therefore JIS G4051 seamless steel pipes have good welding performance and mechanical properties, easy to cut and process.
