SUS630 ( 17-4PH ) Cold Rolled Stainless Steel Strip In Coil And Sheet Plate
Material SUS630 ( 17-4PH ) is a martensitic precipitation hardening stainless steel that provides an outstanding
combination of high strength, good corrosion resistance, good mechanical properities at temperatures up to
316℃, good toughness in both base metal and welds, and short time, low temperature heat treatments that
minimize warpage and scaling.
17-4PH stainless is widely used in the aerospace, chemical, petrochemical, food processing, paper and
general metalworking industries.

Standard Heat Treatments
As supplied from the Mill in Condition A, 17-4 PH Stainless Steel can be heat treated at a variety
of temperatures to develop a wide range of properties. Eight standard heat treatments have been developed.
The following chart outlines the times and temperatures required.
This alloy exhibits useful mechanical properties in Condition A.
Condition A material has been used successfully in numerous applications.
The hardness and tensile properties fall within the range of those for Conditions H 1100 and H 1150.
However, in critical applications, the alloy is used in the precipitation-hardened condition, rather than Condition A.
Heat treating to the hardened condition, especially at the higher end of the temperature range, stress relieves the
structure and may provide more reliable resistance to stress corrosion cracking than in Condition A.
