Product Description

ASTM SA179 S400 Black Coating Alloy Seamless Steel Pipe Wholesale DN200 STD Q345B Seamless cold drawn low-carbon steel pipes for heat exchangers and condensers
ASTM A179/A179M-90a (Reapproved 2001)

Cold drawn seamless low-carbon steel heat exchanger and condenser steel pipes

Scope of application: 1. This standard is applicable to the thinnest seamless steel pipes used in tubular heat exchangers, condensers, and similar heat transfer devices;

2. This standard is applicable to steel pipes ranging from 3.2 to 76.2mm.

General requirements: Unless otherwise specified in this standard, it shall also comply with the applicable clauses of ASTM A450/A450M.

Surface quality: No oxide scale, other surface quality shall comply with ASTM A450/A450M regulations.

Brand and chemical composition (%) C Mn P S

0.06-0.18 0.27-0.63 ≤ 0.035 ≤ 0.035

Note: It is not allowed to provide alloy grades that specifically require the addition of elements other than those mentioned above.

Heat treatment: After the final cold drawing, perform heat treatment at a temperature not lower than 650 ºC.

Hardness test: HRB ≤ 72, sampling requirement is to take any two steel pipes from each batch for Rockwell hardness test. The so-called batch refers to all steel pipes with the same nominal diameter and wall thickness produced from the same furnace without cutting. If it is a batch furnace, the batch only refers to steel pipes with the same furnace number, size, and heat treatment in the same furnace;
