17-7PH Stainless Steel Round Bar AISI 631 UNS S17700 chemical
composition
Description
17-7PH Stainless Steel Round Bar Precipitation Hardening Alloy is a
semi-austenitic stainless steel which is austenitic in the annealed
condition, but martensitic in the hardened condition. 17-7PH
Stainless Steel Round Bar provides high strength and hardness,
excellent fatigue properties, good corrosion resistance and minimum
distortion upon heat treatment. 17-7PH Stainless Steel Round Bar is
easily formed in the annealed condition, then hardened to high
strength levels by simple heat treatments to Conditions RH 950 and
TH 1050. The exceptionally high strength of Condition CH 900 offers
many advantages where limited ductility and workability are
permissible.
All of 17-7PH Stainless Steel Round Bar AISI 631 UNS S17700 conform to Military standard, nuclear power. 100% Ultrasonic test
ASTM E2375 /SAE AMS 2154 /SEP 1923 /GB/T 4162 /EN 10228-3.

FAQ
Q: How do you control the quality?
A: We have professional inspectors to analyze the chemical
composition of raw materials and test the finished products in
strict accordance with the standards stipulated in the contract. In
this process, the inner and outer surfaces, the appearance of both
ends, bending, set length, outer diameter and Wall thickness will
be checked one by one. You can rest assured that all products you
receive from us are reliable.
Q: Do you accept customization?
A: Yes. If you have special requirements for products or packaging,
we can make them for you.
Q: Can you accept trial orders?
A: Our MOQ is usually 1 ton. However, if you want to place an order
as the start of our cooperation, we can accept smaller quantities
at the first time. Of course, after the start, we will have further
and longer cooperation.
Q: How do I get samples?
A: Free samples are available for your inspection and testing,
DHL/FedEx/UPS accounts can be used for sampling, and the courier
fee is borne by you.
