As per heat treatment of AISI 309 pipes, we could do solution treatment, annealed treatment as per the requirement of the clients

As per material of AISI 309 pipes, our raw material has been melted by  EAF+VOD-ESR methods

We produce AISI 309 seamless pipes and weled pipes as per the standard of ASTM B729 and ASTM B464

In order to control the quality of 309 seamless pipes and weled pipes, we will do Positive material identification (PMI),Visual inspection,Dimensional inspection.Laser micrometer inspection,Destructive testing( includes tensile, hardness, bending, flattening, flare and metallurgical tests),ultrasonic testing and pressure testing,Liquid Penetrate testing as per the requirement of the clients

Our AISI 309 pipes are packed wooden crates lined with wax craft paper, tri-wall clay-coated reinforced cases

Our AISI 309 seamless pipe and weled pipes are widely used in many industry :bearing industry, power-generation including steam and gas-turbine, wind energy, mining and construction equipment, oil & gas, petrochemical, defense, rail transportation, and a wide variety of general industrial applications and so on


We could supply AISI 309 pipe material certificate as per En10204-3.1 or EN10204-3.2 by third parts(like TUV,DNV,GL,and so on)
