347/347H,1.4550,1.4961 Stainless steel tube
Product Name : 347 stainless steel tube
Steel Grade : 300 series
Outer Diameter： 8-2500mm
Stainless steel 347 UNS S34700 has good mechanical properties, suitable for use in high temperature environment. SS 347 also has good intergranular corrosion resistance at chromium carbide precipitation temperatures between 800 and 1500 degrees Fahrenheit.SS 347 is similar to SS 321 in terms of intergranular corrosion, which is achieved by using niobium as a stabilizing element to maximize this property.SS347 can not be quenched by heat treatment, but can be improved by cold reduction.SS347h is an improvement of SS347 with a higher carbon content to provide better high temperature strength.

Advantage of Jianglin Seamless Pipe
All about the detail of seamless pipe production.
All of Jianglin raw seamless pipe raw billet are from famous mills like Walsin , Yongxing etc . And
We have advanced NDT equipments for the tests such as Eddy Current test, Ultrasonic test , Hydraulic test and so on . We have ISO 9001 and PED certificate , and the Third Party Inspection Certificates such as TUV , BV , Lloyd’s , SGS , etc , also can be provided according to customers’ requirements .
Each and every pipe will be safely packed into a professional export wooden box. after ordering, our logistics team will check and customize the box to fit into containers.

STAINLESS STEEL BRIGHT ANNEALED TUBE
Inner roughness Ra 0.4um
Specialized in oiled cold drawing, precision rolling & bright annealed, making the inner and outer pipe surface bright, the roughness can be reach Ra 0.4 um after our polishing process.
Bright annealing process make the tube inside and outside surface cleaner, meanwhile, this process can guarantee good mechanical property of nickel alloy and super alloy.
For precise stainless seamless tube, each and every tube will be packed into a respective plastic bag, and guarantee the delivery safety.
Quality control is our best advantage
We not only test the raw material chemical composition, but also the intergranular test to guarantee the stable structure.
All of our pipes and tubes will be straightened based on standards. TIR is highly guaranteed.
For precise tube and pipes, we not only stick to standards, but also accept customized tolerance preference.
X Ray test
For welded pipe, we invest greatly on X ray test lab, just want to guarantee all our product meet clients requirement
Surface roughness test
For inner side and outer side surface roughness, we will test it for clients and synchronize all the pictures.
For stainless steel tubes, we have a high requirement on tube line marking, tube package.
with best clients from all over the world
Exhibition all over the world
Package & Loading
With years of experience，we provide different packing and loading method， from basic packing， to wooden box，and we also provide nest packaging.
We commit to respond every inquiry within 10 hours on week days
