Properties and Applications
SUSXM7
SUSXM7 Japan SUS series stainless austenitic stainless steel
Standard: Japan JIS standard
Features: addition of copper in 304 steel; improved cold workability. SUSXM7
used for cold heading and other parts.
SUSXM7 correspond GB 0Cr18Ni9Cu3, low-carbon, low nitrogen, sulfur, is deformed
steel 304, high copper content, easy molding, generally used for Allen, coach
screws, self-tapping screws and other higher degree of deformation of the
product. It is similar in chemical composition 302HQ specification, due to price
reasons, it is the emergence of an alternative identity 302HQ, but in actual
use, there are still differences, a penny stock, mainly in the magnetic stronger
than the real 302HQ processability quite different in terms of small diameter,
such as when processing glasses small screws best to use real Nippon 302HQ
material [1] material. Of course, if the requirements are not very demanding,
XM7 is a good choice. Chemical composition and SUS302HQ main difference SUSXM7
on some trace elements, but the main component of stainless steel wire from
view, their specifications are very similar, basically no difference. However,
in actual use, the magnetic and processing performance can be a judge, but this
requires experience, if you want to explicitly determine the best material to do
testing. Because almost XM7 and 302HQ main ingredient, so many manufacturers
will XM7 also called 302HQ.
SUS631
Japan SUS631 (17-7PH GB 0Cr17Ni7Al) is a precipitation hardening stainless
steel, high strength and hardness, fatigue, has good corrosion resistance and
formability, and when the temperature and little distortion, this steel good
performance, especially Application and aerospace fields, this particular alloy
is also suitable for other areas of high-strength, corrosion resistance
requirements. In the high temperature to 316 ¢J, the spring performance is still
good. SUS631 used in aerospace, chemical, petrochemical, paper and metal
processing industry.
