0.5-80mm Thickness ASTM A179 Gr.B Hot Rolled Steel Pipe For Engineering Construction
ASTM A179 is a seamless cold-drawn mild steel pipe used primarily in the manufacture of heat exchangers and condensers.
The chemical composition of this steel pipe includes: carbon (C) content between 0.06% and 0.18%, manganese (Mn) content between 0.27% and 0.63%, phosphorus (P) content up to 0.035%, sulfur (S) content up to 0.035%. It is also known as No. 10 Premium mild steel. It should be noted that not all steels that meet these chemical compositions can be used to make A179 steel pipes, and other requirements of ASTM standards such as surface finish and hardness need to be met.

Production process of hot rolled tubes
Hot rolling → heating → piercing → three roller helical rolling, tandem rolling or extrusion → tube knockout → sizing or tube diameter reduction → cooling → semi-finished hot rolled seamless pipe → straightening → water pressure test → labeling → warehousing.
Classifications :
Hot rolled seamless steel tubes can be classified into the common steel pipe, low and medium pressure boiler seamless steel tube, high pressure boiler seamless pipe, stainless steel hot rolled pipe, and more.
Advantages
Due to our adoption of hot rolling process, the original casting structure of the steel slab for making hot rolled pipe is destroyed. This means that the crystalline grains of steel material are refined, and the defects of the microstructure of steel slab are eliminated, which results in improved mechanical performance and denser microstructure of steel materials along the rolling direction.
Hence, our hot rolled seamless steel pipe features good mechanical property and superior intensity.
